Abstract: Method and compositions are provided for preparing concentrated emulsions of organic compounds which are recalcitrant to aqueous solubilization. The compositions are useful for increasing the practical utility of aqueous-recalcitrant compounds for a variety of established functions. The highly concentrated emulsions are prepared through a two step mixing process. The invention is exemplified by preparation of stable saponin-based emulsions containing greater than 50% by weight benzyl benzoate, benzyl salicylate, cedryl acetate, D- or L-limonene, cinnamic aldehyde, and vanillin.

Abstract: Compositions and methods are provided for activation of endogenous plant pathogen resistance pathways, including systemic acquired resistance, the hypersensitive reaction response and the upregulation of pathogenesis related proteins. The compositions comprise as active agents one or more naturally occurring compounds or essential oils selected from cedar oil, cinnamon oil, grapefruit oil, grapefruit seed extract oil, ferulic acid and acetyl salicylic acid. The methods involve directly applying formulations comprising one or more of these active agents to a Gymnosperm to induce endogenous plant defense pathways as a therapeutic or prophylactic treatment against fungal pathogens such as pitch canker and white pine blister rust.

Abstract: The invention is directed to methods and compositions for controlling a pest population using one or more carboxy ester compounds which comprise aromatic acids, aliphatic acids, and/or salicylate derivatives. The invention embodiments disclosed herein are intended for the control of pests such as plant pests and agricultural pests. These pest control methods are helpful in controlling pests by contacting pests with the carboxy ester compounds of the invention. The subject methods will reduce the detrimental environmental impact and health hazards of pest control by minimizing the toxicity of the subject compositions.

Abstract: Methods and compositions based upon natural compounds, including balsam, cinnamic aldehyde, a-hexyl cinnamic aldehyde, and coniferyl aldehyde are provided, which find use as pesticides.

Infestations of a variety of plant parts can be treated, including those of leaves, seeds, seedlings, fruit, flowers and roots. Susceptible organisms include rust, powdery mildew, botrytis, phylloxera, aphids, thrips, codling moth, nematodes and leaf hoppers.

Abstract: Methods and compositions based upon natural flavonoid aldehydes, including cinnamic aldehyde, &agr;-hexyl cinnamic aldehyde, and coniferyl aldehyde are provided, which find use as pesticides. The compositions are effective against pathogenic fungi, arachnids and insects at concentrations which are not phytotoxic to the treated host plant. Infestations of a variety of plant parts can be treated, including those of leaves, seeds, seedlings, fruit, flowers and roots. Susceptible organisms include rust, powdery mildew, botrytis, phylloxera, aphids, thrips, codling moth, nematodes and leaf hoppers.

Abstract: Methods and compositions based upon natural flavonoid and aromatic aldehydes are provided, which find use as pesticides. The compositions are effective against pathogenic fungi and insects at concentrations which are not phytotoxic to the treated host plant. Infestations of a variety of plant parts can be treated, including those of leaves and roots. Susceptible organisms include rust, powdery mildew and aphids.

Abstract: The invention is directed to a method for controlling a pest population using a composition comprising a benzyl ester of an aromatic acid or aliphatic acid or a salicylate. Methods and compositions for controlling a pest population are provided. The compositions comprise a benzyl ester of an aromatic acid or aliphatic acid or a salicylate. The composition can include at least one fatty-acid ester to increase the pesticidal activity. The subject method controls the population of pests such as plant pests or pests infesting a mammal by contacting the pests with the composition. The subject method reduces the environmental and health hazards in pest control by minimizing the toxicity of the subject composition.

Abstract: A method and composition for inhibiting the growth of a weed is described. The herbicidal composition comprises an agriculturally-acceptable carrier in combination with a compound of Formula (I): ##STR1## wherein R.sup.1 is alkylcarbonyl or arylcarbonyl; R.sup.2 is alkyl or H; R.sup.3 is H, OH or alkoxy; R.sup.4 is H or OH; and R.sup.5 is H, OH or alkoxy.

Abstract: The present invention provides methods and compositions for inhibiting microbial growth through the use of aromatic aldehydes or alcohols for the purpose of disinfecting contaminated environments. The methods include the step of contacting the unsterile area with an amount of a aromatic aldehyde or alcohol sufficient to control growth of pathogenic microbes. The aldehyde or alcohol can be provided in a variety of formulations.

Abstract: Methods and compositions based upon natural aromatic compounds are provided, which find use as pesticides. The pesticides are formulated in a variety of ways, including dusts, sprays, shampoos and soaps, and can be bound to a solid support or provided as bait or directly impregnated into organic matter infested by or susceptible to infestation by a target pest.

Abstract: Improved sizing compositions for cellulosic products, e.g., paper, are provided by combining first and second composition components while at least the second component is finely divided into fine liquid or solid particles. Component combination in this manner serves to provide especially effective sizing compositions.The first component comprises a material which provides both ammonia and ammonium salt when combined with other materials in the composition. Such ammonia-ammonium salt-providing material comprises at least one material selected from the group consisting of ammonia, or a precursor thereof; ammonium salts, or a precursor thereof; a reaction product of urea and at least one selected Lewis acid; and mixtures of these materials.The second component comprises a saponified, partially saponified or unsaponified rosin that is modified with either an .alpha., .beta.-unsaturated aliphatic acid generally containing from about 3 to 10 carbon atoms, an anhydride of such acids, or mixtures thereof.
