This application is a continuation application of U.S. patent application Ser. No. 14/009,193, filed Oct. 1, 2013, which is a 371 of International Application No. PCT/EP2012/056806 filed Apr. 13, 2012 which claims priority to U.S. Provisional Patent Application No. 61/475,863 filed Apr. 15, 2011, to which the contents of all are incorporated herein by reference.
FIELD OF TECHNOLOGYThe present disclosure relates generally to the use of nematode-antagonistic biocontrol agents, and more particularly, to combinations of at least one nematode-antagonistic biocontrol agent and one or more defined agents. Methods of using these may include, for example, methods in agriculture to improve the growing characteristics of a plant. Methods for using such combinations may also include, control of damage by pests, such as insect, nematode and pathogen, especially in the agricultural field.
BACKGROUNDA variety of different active ingredients, agents and combinations are described in the literature for, inter alia, improving plant growth; however, such known uses do not always satisfy the needs of agricultural practice in many incidents and aspects. There is a continuing need to provide improved combinations, which may provide better, for example, biological properties, e.g., synergistic properties, especially for controlling pests. Further, biological properties of known combinations are not always entirely satisfactory in the areas of pest control, phytotoxicity, and environmental and worker exposure, for example. In particular, in the instance a pest has become, or risks becoming resistant to the known compositions or active ingredients, improved methods of control or prevention are sought.
One such pest known to damage crops is the nematode. There are many types of nematode pests, one such nematode is the soybean cyst nematode (SCN), Heterodera glycines Ichinohe. SCN causes substantial losses in soybean production. Yield suppression attributed to H. glycines alone resulted in an estimated $750 million in losses to U.S. soybean producers annually from 2003 to 2005 (Wrather, J. A., and Koenning, S. R., Estimates of disease effects on soybean yields in the United States 2003 to 2005, J. Nematol. 38:173-180, 2006).
In light of the methods currently used to control pests, for example, nematode pests, applicants believe there remains a further need for increased pest control. Applicants also desire to reduce the rate at which pests acquire an increasing tolerance to both pest resistant crop plants and pesticides. Applicants also desire to extend the useful life of both pest resistant crop plants and pesticides. Various aspects of the instant disclosure may be directed to at least one of the above mentioned, or additional, problems.
SUMMARYBy way of summary, the present technology includes combinations of at least one nematode-antagonistic biocontrol agent and one or more defined agents.

Each combination according to the invention is especially advantageous for the treatment of plant propagation material. Examples of specific combinations encompassed by the invention include, but are not limited to:
Further examples of specific combinations encompassed by the invention include, but are not limited to:
In a preferred embodiment, the combination is in the form of a composition, which further comprises (III) one or more customary formulation auxiliaries. In a preferred embodiment, each combination is a composition that is in the form of a pre-mix formulated composition.
Combinations may demonstrate synergistic activity compared to the activity of the individual ingredients in the combination. There may be more than one agent, independently of each combination, from (II). The disclosure, therefore, makes available an improvement over the art.
Controlling, preventing or protecting and its inflections, within the context of the present invention, mean reducing any undesired effect, such as infestation or attack, and damage by a pest on a plant, part of the plant or plant propagation material to such a level that an improvement is demonstrated.
Each combination according to the invention may have advantageous properties for protecting plants against, for example, (i) pathogenic, such as phytopathogenic, especially fungi, attack or infestation, which result in disease and damage to the plant and/or (ii) insect or nematode attack or damage; particularly in the instance of plants, the present invention can control or prevent the pest damage on a seed, or parts of plant, plant organs and/or plants Further, a combination according to the invention, in the absence of pathogenic or insect and/or nematode pressure, may improve the growth of a plant.
Such properties are for example the synergistically enhanced actions of combinations compared to the individual ingredients of the combination (e.g. (I), and (II)), resulting in, for example, lower pathogenic pest damage, lower rates of application, or a longer duration of action. In the instance of agriculture, the enhanced actions may show an improvement in the growing characteristics of a plant by, for example, higher than expected control of the pest damage, or higher than expected yield, stand establishment, germination, etc.
The improvement in the growing (or growth) characteristics of a plant can manifest in a number of different ways, but will typically result in a better product of the plant. It can, for example, manifest in improving the yield and/or vigour of the plant or quality of the harvested product from the plant, which improvement may not be connected to the control of pests, such as fungi, insects and nematodes.
As used herein the phrase “improving the yield” of a plant relates to an increase in the yield of a product of the plant by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the subject method. It is preferred that the yield be increased by at least about 0.5%, more preferred that the increase be at least about 1%, even more preferred is about 2%, and yet more preferred is about 4%, or more. Yield can be expressed in terms of an amount by weight or volume of a product of the plant on some basis. The basis can be expressed in terms of time, growing area, weight of plants produced, amount of a raw material used, or the like.
As used herein the phrase “improving the vigour” of a plant relates to an increase or improvement of the vigour rating, or the stand (the number of plants per unit of area), or the plant height, or the plant canopy, or the visual appearance (such as greener leaf colour), or the root rating, or emergence, or protein content, or increased tittering, or bigger leaf blade, or less dead basal leaves, or stronger tillers, or less fertilizer needed, or less seeds needed, or more productive tillers, or earlier flowering, or early grain maturity, or less plant verse (lodging), or increased shoot growth, or earlier germination, or any combination of these factors, or any other advantages familiar to a person skilled in the art, by a measurable or noticeable amount over the same factor of the plant produced under the same conditions, but without the application of the subject method.
When it is said that the present method is capable of “improving the yield and/or vigour” of a plant, the present method results in an increase in either the yield, as described above, or the vigor of the plant, as described above, or both the yield and the vigor of the plant.
In an embodiment, application to a plant, or propagation material thereof, a combination of nematode-antagonistic biocontrol agent and any one of thiamethoxam or cyantraniliprole provides improved yield and/or vigour. The application of the combination helps counter possible negative field conditions which expose plants to various stress factors, such as drought and floods
Accordingly, the present disclosure also provides a method of improving the growing characteristics of a plant, which comprises applying to the plant, part of plant, and/or plant propagation material, the ingredients of the combination, as defined in the first aspect, in any desired sequence or simultaneously, especially in the absence of pathogenic or pests pressure.
Combinations of the disclosure can be used in the agricultural sector and related fields of use for controlling or preventing damage by pests, such as insect, nematode and pathogen.
Combinations according to the present disclosure, especially those containing (II) one or more pesticidal agents selected, independently from each other, from (B), (C), and (D), may be effective against pest control, such as control of pests selected from Nematoda, Insecta and Arachnida. In that instance, the combination can also be applied on the pest to control or prevent pest damage and protect the desired material (e.g. plant and part of plant) from pest damage.
Particular pests controlled by the compositions of the present technology include those from the class Nematoda, for example, the species of Tylenchus spp., Atylenchus spp., Anguina spp., Rotylenchus spp., Criconema spp., Tylenchulus spp., Paratylenchus spp., Aphenlenchus spp., Bursaphelenchus spp., Paralongidorus spp., Trichodorus spp., Meloidogyne spp. (for example, Meloidogyne incoginita and Meloidogyne javanica), Heterodera spp. (for example, Heterodera glycines, Heterodera schachtii, Heterodora avenae and Heterodora trifolii), Globodera spp. (for example, Globodera rostochiensis), Radopholus spp. (for example, Radopholus similes), Rotylenchulus spp., Pratylenchus spp. (for example, Pratylenchus neglectans and Pratylenchus penetrans), Aphelenchoides spp., Helicotylenchus spp., Hoplolaimus spp., Paratrichodorus spp., Longidorus spp., Nacobbus spp., Subanguina spp. Belonolaimus spp., Criconemella spp., Criconemoides spp. Ditylenchus spp., Dolichodorus spp., Hemicriconemoides spp., Hemicycliophora spp., Hirschmaniella spp., Hypsoperine spp., Macroposthonia spp., Melinius spp., Punctodera spp., Quinisulcius spp., Scutellonema spp., Xiphinema spp., and Tylenchorhynchus spp.
In the instance a combination contains (II) (F) Harpin, such a combination is also effective for improving the growth of a plant through, for example, activating the natural defence mechanism in the host plant, referred to as systemic acquired resistance (SAR) and/or nematode control, such as Meloidogyne spp. (for example, Heterodera spp. (for example, Heterodera glycines, Heterodera schachtii, Heterodora avenae and Heterodora trifolii).
Isoflavones are plant chemicals which occur largely in members of the Leguminosae plant family and two such examples are those defined in (II) (E). They are based on a simple diphenolic ring structure as described for example by Carlson et al (1980) Journal of Chromotography, 198, 193-197 and U.S. Pat. No. 7,033,621, the contents of which are incorporated by reference. Examples of isoflavones include, but are not limited to, genistein, biochanin A, formononetin, daidzein, glycitein, hesperetin, naringenin, chalcone, coumarin, Ambiol (2-methyl-4-[dimethylaminomethyl]-5-hydroxybenzimidazole), ascorbate and pratensein and the salts and esters thereof. The present invention contemplates the use of both naturally-occurring and synthetic isoflavone compounds.
In the instance a combination contains (II) one or more agents (E), such a combination is also effective for improving the growth of a plant through, for example, better availability of nutrients to the plant, such as water, and sulfates, nitrates, phosphates and metals, by improving the uptake by the roots.
The combinations according to the invention offers opportunities to manage resistance in pests, for example, Plutella spp. as well as to proactively manage insecticide resistance in various pests.
In the instance a combination contains (II) one or more agents (F) and/or (G), such a combination may also be effective for enhancing the plants' traits. Examples of enhanced plant traits include, but are not limited to, increased stem girth, change in leaf color, early flowering, synchronization in flowering, decrease in the lodging, control of the canopy size of a plant, delaying or eliminating tie-up of crops, increase in the disease resistance, enhancing the water utilization/improving the water use efficiency, including but not limited to decreasing the watering and/or less frequent watering (demonstrated by less wilting of the plant, the ability of the plant to rejuvenate following a suspension in watering), higher yield, higher quality/healthier plant appearance, greater transportability, decreasing the insect damage, and smaller plant canopies. Synchronized flowering is indicated by blooms materializing within 0.5 to 1 days of one another throughout the entire crop. Such a combination is particularly well suited for use for plants and propagation material thereof which are transplanted.
In an embodiment, further agent(s), such as active ingredient(s), can be used with each combination according to the present invention. Therefore, each of the combinations of the present invention may be mixed with, for example, one or more other known pesticides, such as other fungicides, insecticides, nematicides, etc. The use of additional agents, such as other active ingredients, can be for reasons, for example, broader spectrum control (e.g. wider variety of pests, diseases, etc), lower rates, synergy and economy. A skilled person would understand that a single pesticidal active ingredient may have activity in more than one area of pest control, for example, a pesticide may have fungicide, insecticide and nematicide activity. Specifically, aldicarb is known for insecticide, acaricide and nematicide activity, while metam is known for insecticide, herbicide, fungicide and nematicide activity, and thiabendazole and captan can provide nematicide and fungicide activity.
Combinations of the disclosure can be formulated for a particular use. Preferably, each combination is formulated for protecting cultivated plants or their propagation materials. Accordingly, each combination of the invention can be applied to the plant in a conventional manner, such as foliar spray. Advantageously, each of the combinations are formulated for plant propagation material, such as seed, treatment applications for improving the growth of a plant derived from the treated material (or seed), for example, by controlling or preventing damage by pests and/or pathogens, which are found in agriculture and forestry, and can particularly damage the plant in the early stages of its development.
Further, the present invention also envisages soil application of the combinations of the invention to control the soil-dwelling pests and/or soil-borne pathogens. Methods of applying to the soil can be via any suitable method, which ensures that the combination penetrates the soil, for example, nursery tray application, in furrow application, soil drenching, soil injection, drip irrigation, application through sprinklers or central pivot, incorporation into soil (broad cast or in band) are such methods.
The benefits from the invention can also be achieved either by (i) treating plant propagation material with a combination or (ii) applying to the locus where control is desired, generally the planting site, the combination, or both (i) and (ii). Indeed, the benefits from the invention can also be achieved by treating plant propagation material with one or more of the ingredients of the combination, and then applying to the locus where control is desired with the other ingredient(s) of the combination.
The term “plant propagation material” is understood to denote all the generative parts of the plant, such as seeds, which can be used for the multiplication of the latter and vegetative plant materials such as cuttings and tubers (for example, potatoes). Accordingly, as used herein, part of a plant includes propagation material. There may be mentioned, e.g., the seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes, parts of plants. Germinated plants and young plants, which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion.
Parts of plant and plant organs that grow at later point in time are any sections of a plant that develop from a plant propagation material, such as a seed. Parts of plant, plant organs, and plants can also benefit from the pest damage protection achieved by the application of each combination on to the plant propagation material. In an embodiment, certain parts of a plant and certain plant organs that grow at later point in time can also be considered as plant propagation material, which can themselves be applied (or treated) with the combination; and consequently, the plant, further parts of the plant and further plant organs that develop from the treated parts of plant and treated plant organs can also benefit from the pest damage protection achieved by the application of each combinations on to the certain parts of plant and certain plant organs.
Methods for applying or treating pesticidal active ingredients and mixtures thereof on to plant propagation material, especially seeds, are known in the art, and include dressing, coating, pelleting and soaking application methods of the propagation material. Such methods are also applicable to the combinations according to the invention. In a preferred embodiment, the combination is applied or treated on to the plant propagation material by a method such that the germination is not induced; generally seed soaking induces germination because the moisture content of the resulting seed is too high. Accordingly, examples of suitable methods for applying (or treating) a plant propagation material, such as a seed, is seed dressing, seed coating or seed pelleting and alike.
It is preferred that the plant propagation material is a seed.
Although it is believed that the present method can be applied to a seed in any physiological state, it is preferred that the seed be in a sufficiently durable state that it incurs no damage during the treatment process. Typically, the seed would be a seed that had been harvested from the field; removed from the plant; and separated from any cob, stalk, outer husk, and surrounding pulp or other non-seed plant material. The seed would preferably also be biologically stable to the extent that the treatment would cause no biological damage to the seed. It is believed that the treatment can be applied to the seed at any time between harvest of the seed and sowing of the seed or during the sowing process (seed directed applications). The seed may also be primed either before or after the treatment.
Even distribution of the ingredients in the combination and adherence thereof to the seeds is desired during propagation material treatment. Treatment could vary from a thin film (dressing) of the formulation containing the combination, for example, a mixture of active ingredient(s), on a plant propagation material, such as a seed, where the original size and/or shape are recognizable to an intermediary state (such as a coating) and then to a thicker film (such as pelleting with many layers of different materials (such as carriers, for example, clays; different formulations, such as of other active ingredients; polymers; and colourants) where the original shape and/or size of the seed is no longer recognisable.
An aspect of the present invention includes application of the combinations onto the plant propagation material in a targeted fashion, including positioning the ingredients in the combination onto the entire plant propagation material or on only parts thereof, including on only a single side or a portion of a single side. One of ordinary skill in the art would understand these application methods from the description provided in EP954213B1 and WO06/112700.
The combinations described herein can also be used to enhance the growth of a plant through treating, or applying, a combination according to the present on to a “pill” or a suitable substrate and placing, or sowing, the treated pill, or substrate, next to a plant propagation material. Such techniques are known in the art, particularly in EP1124414, WO07/67042, and WO07/67044.
Application of the combinations described herein onto plant propagation material also includes protecting the plant propagation material treated with the combination of the present invention by placing one or more pesticide-containing particles next to a pesticide-treated seed, wherein the amount of pesticide is such that the pesticide-treated seed and the pesticide-containing particles together contain an Effective Dose of the pesticide and the pesticide dose contained in the pesticide-treated seed is less than or equal to the Maximal Non-Phytotoxic Dose of the pesticide. Such techniques are known in the art, particularly in WO2005/120226.
Application of the combinations onto the seed also includes controlled release coatings on the seeds, wherein the ingredients of the combinations are incorporated into materials that release the ingredients over time. Examples of controlled release seed treatment technologies are generally known in the art and include polymer films, waxes, or other seed coatings, wherein the ingredients may be incorporated into the controlled release material or applied between layers of materials, or both.
Seed can be treated by applying thereto the insecticidal compound (I) and at least one agent (II) in any desired sequence or simultaneously.
The seed treatment occurs to an unsown seed, and the term “unsown seed” is meant to include seed at any period between the harvest of the seed and the sowing of the seed in the ground for the purpose of germination and growth of the plant.
Treatment to an unsown seed is not meant to include those practices in which the active ingredient is applied to the soil but would include any application practice that would target the seed during the planting process.
Preferably, the treatment occurs before sowing of the seed so that the sown seed has been pre-treated with the combination. In particular, seed coating or seed pelleting are preferred in the treatment of the combinations according to the invention. As a result of the treatment, the ingredients in each combination are adhered on to the seed and therefore available for pest control.
The treated seeds can be stored, handled, sowed and tilled in the same manner as any other active ingredient treated seed.
Each combination according to the present invention is suitable for plants of the crops: cereals, such as wheat, barley, rye, oats, rice or sorghum; maize (fodder maize and sugar maize/sweet and field corn); beet, such as sugar or fodder beet; fruit, for example pomaceous fruit, stone fruit, tree nut or soft fruit, such as apples, pears, plums, peaches, bananas, almonds, walnuts, pistachios, cherries or berries, for example strawberries, raspberries or blackberries; leguminous crops, such as beans, lentils, peas or soya; oil crops, such as oilseed rape, mustard, poppies, olives, sunflowers, coconut, castor, cocoa or ground nuts; cucurbits, such as pumpkins, marrow, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, iceberg, carrots, onions, tomatoes, paprika, potatoes or bell peppers; Lauraceae, such as avocado, Cinnamonium or camphor; and also tobacco, nuts, coffee, eggplants, sugarcane, tea, pepper, grapevines, hops, the plantain family including bananas, latex plants, lawn, turf, fodder grass, and ornamentals, such as petunias, geranium/pelargoniums, pansies and impatiens; and shrubs, broad-leaved trees and evergreens, such as conifers. In particular, the combination is suitable for coffee, citrus, stone fruits (especially apple, pears, plums, peaches), tree nuts (especially almonds and pistachios), and vegetable crops. In particular, cotton, soya, cereals, maize, vegetables, and bananas.
Each of the combinations according to the present invention are particularly suitable for use in maize, cereals (including rice), oil seed rape/canola, soybean, cotton, sugar beet, sunflower, potato, beans, sorghum, peas, peanuts, bananas, as well as vegetables such as cale crops, and fruiting vegetables.
The term “crops” is to be understood as including also crop plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.
Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins from Bacillus cereus or Bacillus popilliae; or insecticidal proteins from Bacillus thuringiensis, such as δ-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases.
In the context of the present invention there are to be understood by δ-endotoxins, for example Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for example Vip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G-recognition sequence is inserted into a Cry3A toxin (see WO 03/018810).
Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP0374753A, WO 93/07278, WO 95/34656, EP0427529A, EP451878A and WO 03/052073.
The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP0367474A, EP0401979A and WO 90/13651.
The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera).
Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGard Rootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGard Plus® (maize variety that expresses a Cry1Ab and a Cry3Bb1 toxin); Starlink® (maize variety that expresses a Cry9C toxin); Herculex I® (maize variety that expresses a Cry1Fa2 toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses a Cry1Ac toxin); Bollgard II® (cotton variety that expresses a Cry1Ac and a Cry2Ab toxin); VipCot® (cotton variety that expresses a Vip3A and a Cry1Ab toxin); NewLeaf® (potato variety that expresses a Cry3A toxin); NatureGard®, Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

The rates of application (use) of a combination vary, for example, according to type of use, type of crop, the specific agent (II) in the combination, type of plant propagation material (if appropriate), but is such that the active ingredients in the combination is an effective amount to provide the desired enhanced action (such as disease or pest control) and can be determined by trials and routine experimentation known to one of ordinary skill in the art.
Generally for foliar or soil treatments, application rates can vary from 0.05 to 3 kg per hectare (g/ha) of ingredients.
Generally for seed treatments, application rates can vary from 0.5 to 1000 g/100 kg of seeds of ingredients. In an embodiment, compound (I) is applied at a rate of 0.01 to 2, preferably 0.03 to 1.5, mg ai/seed, depending on the crop. Whereas the rates of application of the agents indicated in (A), (B), (C), (D) and (E) can vary depending on the specific agent and type of crop. Such rates would be readily available to a skilled person.
The methods according to the invention for controlling pests of the abovementioned type is carried out in a manner known per se to those skilled in the art, depending on the intended aims and prevailing circumstances, that is to say by spraying, wetting, atomizing, dusting, brushing on, seed dressing, scattering or pouring of the composition. In the case of spore forming bacteria and fungi, the application rates with respect to plant propagation material (e.g. seed treatment) preferably range from about 1×105 to 1×1012 (or more) spores/seeds. Preferably, the spore concentration is about 1×106 to about 1×1011 spores/seed. Similar application rates may also be used for agents indicated in (D). For example, Bacillus species may be present in the range of about 1×105 to 1×1012 (or more) colony forming units CFU)/seeds. In another example, the cell concentration is in the range of about 1×106 to about 1×1011 CFU/seed.
The plant propagation material treated by each combination of the present disclosure may be, therefore, resistant to pest damage; accordingly, the present invention also provides a pest resistant plant propagation material which is treated with each combination and consequently at least the ingredients thereof are adhered on the propagation material, such as seed.
The seed treatment combinations and compositions can also comprise or may be applied together and/or sequentially with further active compounds. These further useful active compounds can be fertilizers or micronutrient donors (such as Mo, Zn and/or Co) or other preparations that influence plant growth, such as inoculants (e.g. a strain of nitrogen-fixing bacteria), plant inducers (e.g. nod factors such as disclosed in US2005187107).
In a preferred embodiment of the invention, soybean seeds and transgenic soybean seeds are treated with a combination of the present invention. In addition, the soybean seeds may be inoculated with an appropriate strain of nitrogen-fixing bacteria for the purpose of promoting plant growth. Preferably, seeds may be inoculated with an effective bacterial strain such as Rhizobium spp. or Azospirillium spp. before sowing. The primary effect of such bacteria is in the fixation of atmospheric nitrogen into a usable form for the plant Rhizobia bacteria, for example, is especially preferred in order to form nodules on the plant roots that are sustained by the plant and in turn provide nitrogen for the plant as mentioned above.
In a further embodiment, a soybean plant propagation material is treated with a plant inducer, e.g. a nod factor derived from Bradyrhizobium japonicum, Sinorhizobium fredii, Sinorhizobium meliloti, Bradyrhizobium sp. (Arachis), or Rhizobium leguminosarum biovar phaseoli, viceae, or trifolii.
In an aspect, the present invention also envisages use of the combinations of the present invention with glyphospate tolerant plants, especially glyphospate tolerant soybean plants, in particular for the control of asian soybean rust. Accordingly, the present invention provides a method comprising (α) applying a combination according to the invention as defined in the first aspect, especially those containing (II) one or more pesticidal agents (A), to a glyphosate tolerant plant propagation material, preferably soybean propagation material, and (β) applying a pesticidal composition (B) to the resulting plant, part of plant and/or the locus thereof one or more times (i) before emergence, (ii) after emergence, or (iii) both (i) and (ii), provided that pesticide composition (B) comprises glyphosate.
Generally, glyphosate-containing composition can be applied, if applied only once, at a rate of 960 g ai/ha; if applied twice the rate can vary from 1200 to 1680 g ai/ha. The rates and number of applications vary according to the particular conditions. Preferably, the composition (B) is applied three times with an application rate of 960, 720 and 400 g ai/ha respectively. In such an embodiment, the present invention controls, prevents or treats Phakopsora pachyrhizi and/or P. meibomiae, especially Phakopsora pachyrhizi.
Each of the combinations of the present invention may also comprise alkali metal, alkaline earth metal, metal, or ammonium salts. Zinc chloride and alkali metal, alkaline earth metal, or ammonium salts of mineral acids, especially nitrates, phosphates, sulfates, chlorides, and carbonates of sodium, potassium, ammonium, magnesium, and calcium are preferred.
Depending upon the particular plant propagation material to be treated, the conditions under which it is to be stored, and the soil and weather conditions under which it is expected to germinate and grow, the combinations of the present invention may include a wide spectrum of one or more additives. Such additives include, but are not limited to, uv-protectants, pigments, dyes, extenders such as flour, dispersing agents, excipients, anti-freezing agents, preservatives, herbicidal safeners, seed safeners, seed conditioners, micronutients, fertilizers, biocontrol agents, surfactants, sequestering agents, plasticizers, colorants, brighteners, emulsifiers, flow agents such as calcium stearate, talc and vermiculite, coalescing agents, defoaming agents, humectants, thickeners, waxes, bactericides, insecticides, pesticides, and fillers such as cellulose, glass fibers, clay, kaolin, talc, pulverized tree bark (e.g., Douglas fir bark or alderbark), calcium carbonate and wood meal, and odor-modifying agents. Typical excipients include finely divided mineral substances such as pumice, attapulgite, bentonite, kaoline zeolite, diatomite, and other clays, modified diatomaceous adsorbents, charcoal, vermiculite, finely divided organic substances such as peat moss, wood powder, and the like. Such additives are commercially available and known in the art.
The insecticidal compound (I) and one or more agents (II), and optionally any other pesticides, may be used either in pure form, i.e., as a solid active ingredient, for example, in a specific particle size, or preferably together with at least one of the auxiliary (also known as adjuvants) customary in formulation technology, such as extenders, e.g., solvents or solid carriers, or surface-active compounds (surfactants), in the form of a formulation, in the present invention. Generally, the insecticidal compound (I) and one or more agents (II) are in the form of a formulation composition with one or more of customary formulation auxiliaries.
Therefore, each combination of the insecticidal compound (I) and one or more agents (II) is normally used in the form of formulations. The ingredients in the combination can be applied to the locus where control is desired either simultaneously or in succession at short interval, for example on the same day, if desired together with further carriers, surfactants or other application-promoting adjuvants customarily employed in formulation technology. In a preferred embodiment, the ingredients in the combination are applied simultaneously.
In the event ingredients of the combinations are applied simultaneously in the present invention, they may be applied as a composition containing the combination, in which case each of (I) and (II) can be obtained from a separate formulation source and mixed together (known as a tank-mix, ready-to-apply, spray broth, or slurry), optionally with other pesticides, or (I) and (II) can be obtained as single formulation mixture source (known as a pre-mix, concentrate, formulated product), and optionally mixed together with other pesticides.
In an embodiment, each combination of the present invention is applied as a composition. Accordingly, the present invention includes a composition comprising (I) and (II), and optionally other pesticides, and optionally one or more customary formulation auxiliaries; which may be in the form of a tank-mix or pre-mix composition.
In an embodiment, each combination of (I) and (II) with one or more customary formulation auxiliaries is provided in the form of a pre-mix composition (or formulated product).
Alternative to the actual synergistic action with respect to pesticidal activity, the combinations according to the invention also can have surprising advantageous properties which can also be described, in a wider sense, as synergistic activity. Examples of such advantageous properties that may be mentioned are: advantageous behaviour during formulation and/or upon application, for example upon grinding, sieving, emulsifying, dissolving or dispensing; increased storage stability; improved stability to light; more advantageous degradability; improved toxicological and/or ecotoxicological behaviour; or any other advantages familiar to a person skilled in the art.
Examples of foliar formulation types for pre-mix compositions are:
- GR: Granules
- WP: wettable powders
- WG: water dispersable granules (powders)
- SG: water soluble granules
- SL: soluble concentrates
- EC: emulsifiable concentrate
- EW: emulsions, oil in water
- ME: micro-emulsion
- SC: aqueous suspension concentrate

As with the nature of the formulations, the methods of application, such as foliar, drench, spraying, atomizing, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.
The tank-mix compositions are generally prepared by diluting with a solvent (for example, water) the one or more pre-mix compositions containing different pesticides, and optionally further auxiliaries.
Suitable carriers and adjuvants can be solid or liquid and are the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers.
The formulations are prepared in known manner, e.g., by homogeneously mixing and/or grinding the active ingredients with extenders, e.g., solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates, such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones, such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.
The solid carriers used, e.g., for dusts and dispersible powders, are normally natural mineral fillers, such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite, and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g., especially dolomite or pulverized plant residues.
Depending upon the nature of the ingredients to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term “surfactants” will also be understood as comprising mixtures of surfactants.
Particularly advantageous application-promoting adjuvants are also natural or synthetic phospholipids of the cephalin and lecithin series, e.g., phosphatidylethanolamine, phosphatidylserine, phosphatidylglycerol and lysolecithin.
Generally, a tank-mix formulation for foliar or soil application comprises 0.1 to 20%, especially 0.1 to 15%, of the desired ingredients, and 99.9 to 80%, especially 99.9 to 85%, of a solid or liquid auxiliaries (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 20%, especially 0.1 to 15%, based on the tank-mix formulation.
Typically, a pre-mix formulation for foliar application comprises 0.1 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.9 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.
Normally, a tank-mix formulation for seed treatment application comprises 0.25 to 80%, especially 1 to 75%, of the desired ingredients, and 99.75 to 20%, especially 99 to 25%, of a solid or liquid auxiliaries (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 40%, especially 0.5 to 30%, based on the tank-mix formulation.
Typically, a pre-mix formulation for seed treatment application comprises 0.5 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.
Whereas commercial products will preferably be formulated as concentrates (e.g., pre-mix composition (formulation)), the end user will normally employ dilute formulations (e.g., tank mix composition).
Preferred seed treatment pre-mix formulations are aqueous suspension concentrates. The formulation can be applied to the seeds using conventional treating techniques and machines, such as fluidized bed techniques, the roller mill method, rotostatic seed treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The seeds may be presized before coating. After coating, the seeds are typically dried and then transferred to a sizing machine for sizing. Such procedures are known in the art.
In general, the pre-mix compositions of the invention contain 0.5 to 99.9 especially 1 to 95, advantageously 1 to 50, %, by mass of the desired ingredients, and 99.5 to 0.1, especially 99 to 5, %, by mass of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries (or adjuvant) can be a surfactant in an amount of 0 to 50, especially 0.5 to 40, %, by mass based on the mass of the pre-mix formulation.
A preferred embodiment is a plant propagation material treating (or protecting) composition, wherein said plant propagation material protecting composition comprises additionally a colouring agent. The plant propagation material protecting composition or mixture may also comprise at least one polymer from water-soluble and water-dispersible film-forming polymers that improve the adherence of the active ingredients to the treated plant propagation material, which polymer generally has an average molecular weight of at least 10,000 to about 100,000.

COMBINATION EXAMPLESA plug measuring 0.75 inch (approximately 1.9 cm) in diameter and 1 inch (approx. 2.5 cm) in depth was removed from each 3 inch diameter×8 inch deep (approx. 7.6×20 cm) plastic pot. Five thousand Heterodera glycines race 3 eggs were placed at the bottom of the plug hole. A soybean variety 3.6-B6 seed was placed on top of the inoculum. Six replicates were made for each treatment group. In addition to untreated control, the treatment groups were Pasteuria nishizawae, Bacillus firmus, and Pasteuria nishizawae+Bacillus firmus.
Bacillus firmus came applied as a seed treatment (available commercially, for example, from Bayer Crop Science as VOTIVO product, PONCHO/VOTIVO, having Bacillus firmus concentration at least 2×109 cfu/ml+clothianidin (0.13 mg/seed)). A point application containing Pasteuria nishizawae (approximately 5.0×109 spores) was applied directly to the seed in the pot. The plug was replaced in the hole to cover the seed. The soil was Vero Beach (Florida, USA) top soil, pH 5.9 (approximate composition sand 93%, silt 2%, clay 2%, organic matter 3%).
At 28 days after planting, plant height was measured and plants were removed from the pots. Soil was gently rinsed from the roots. The rinsed roots were placed in a 20 mesh over a 60 mesh sieve. The root system was blasted with water to remove cyst nematode females. The 20 mesh sieve was removed and the cysts were washed to the bottom of the 60 mesh sieve. The cysts were rinsed into a tube for counting under a stereoscope. Later the dry root weights were measured.
This example illustrates a combination example according to one embodiment of the disclosure. Results were as follows:
Looking closer at the cyst count as an indicator of nematode control, the data show:
As illustrated, the expected control for the Pasteuria species+Bacillus species combination was 20.88%, however, 78.40% control was observed evidencing a strong synergistic effect of the combination.
