Glycoside-containing agricultural treatment composition

Abstract

This invention describes a composition of matter and a method of treating agricultural substrates in which an active ingredient selected from the group consisting of fungicides, bactericides, insecticides, insect repellents, herbicides and plant growth regulators and mixtures thereof is utilized in conjunction with an amount of a glycoside dispersing agent selected from the group consisting of fructoside, glucoside, mannoside, galactoside, taloside, guloside, alloside, altroside, idoside, arabinoside, xyloside, lyxoside and riboside and mixtures thereof which is sufficient to form an emulsion or dispersion of the active ingredient.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention deals with the forming of dispersions or emulsions and dry product application of various biologically active ingredients.

2. Description of the Art

It is known that various materials such as insecticides, insect repellents, fungicides, bactericides, herbicides, and plant growth regulators may formulated into various products for use on crops, for insect control, weed control and the like. Often, these products are applied as a dry powder or a granular material to the surface which is desired to be treated. In still other cases, the products are formulated as a liquid or a semi-solid dispersion. Whether the method of application is dry or wet, it is advantageous to include within the product a dispersing agent to control the flow of the product to ensure equal distribution of the active ingredient throughout the remaining components of the composition.

The typical composition used for herbicide, fungicide, insecticide, bactericide or herbicide ingredients has ordinarily depended on the end-use method of application. That is, a specific dispersing aid is often employed when the product is to be applied in a powder or dry form and yet a second different dispersing aid is required when the product is to be applied as a semi-solid or liquid composition. It would be advantageous to prepare a product comprising the active ingredient and to utilize a single dispersing agent without regard to whether the final use application of the product is in a liquid or solid formulation. Moreover, the desirability of using a single ingredient as a dispersing agent reduces the possibility for error given the number of chemicals which must be compounded to prepare a herbicide or insecticide product.

It is also highly desirable to incorporate into the compositions with which the present invention deals, a dispersing aid which is not itself environmentally harmful either to the products to which it is applied or to the applicator of the composition. It is also desirable that the dispersing aid aspect of the present invention use a material which has emulsifying characteristics as well as being useful in dispersing the product in its application. It is also desirable to replace materials such as Cellosolve solvents typically used in numerous agricultural formulations. The Cellosolve solvents have been speculated to be carcinogenic materials which may also cause sterility. The particular dispersing agents with which the present invention is concerned have considerably less volatility than do the Cellosolve materials and thus may be retained for longer periods on plants or other surfaces on which the composition is applied. The emulsifying and dispersing capabilities of the dispersing agents of the present invention also make them less resistant to being removed by rain from the surface of a growing plant. The reader is suggested to review U.S. Pat. No. 4,512,989 issued Apr. 23, 1985 to Ohyama et al. for a general disclosure of agricultural compositions with which the present invention is concerned.

Throughout the specification and claims, percentages and ratios are by weight; temperatures are in degrees Celsius and pressures are in KPascals unless otherwise indicated. To the extent applicable, references to patents and articles are herein incorporated by reference.

SUMMARY OF THE INVENTION

This invention describes composition of matter comprising an active ingredient consisting of fungicides; bactericides; insecticides; insect repellents; herbicides and plant growth regulators and mixtures thereof and an effective amount of a glycoside dispersing agent selected from the group consisting of fructoside, glucoside, mannoside, galactoside, taloside, guloside, alloside, altroside, idoside, arabinoside, xyloside, lyxoside and riboside and mixtures thereof in a sufficient amount to form an emulsion or dispersion of the active ingredient.

A further aspect of the invention is a method of treatment an agricultural substrate comprising introducing to the substrate a sufficient amount to accomplish the treatment of a composition of matter comprising an active ingredient consisting of fungicides; bactericides; insecticides; herbicides and plant growth regulators and mixtures thereof and an effective amount of a glycoside dispersing agent selected from the group consisting of fructoside, glucoside, mannoside, galactoside, taloside, guloside, alloside, altroside, idoside, arabinoside, xyloside, lyxoside and riboside and mixtures thereof in a sufficient amount to form an emulsion or dispersion of the active ingredient.

DETAILED DESCRIPTION OF THE INVENTION

Glycosides useful in the present invention include those prepared according to U.S. Pat. No. 3,219,656 to Boettner issued Nov. 23, 1965. Further glycosides which may be used herein include the alkyl polyglycosides described in U.S. Pat. No. 3,598,865 issued Aug. 10, 1971 to Lew. Useful saccharide moieties for the glycoside include fructosides, glucosides, mannosides, galactosides, talosides, gulosides, allosides, altrosides, idosides, arabinosides, xylosides, lyxosides and ribosides and mixtures thereof. The preferred sacchride moieties are glucosides, fructosides and xylosides.

The structural formula R(OG).sub.x as defined herein preferably has the hydrophobic moiety (aglycone portion) of the glycoside containing between about 1 and 30 carbon atoms; preferably from about 1 to about 20 carbon atoms; and most preferably from about 9 to about 18 carbon atoms. In formulations where it is desired to prepare the product as a powdered or polverant material the aglycone portion preferably contains from about 1 to about 8 carbon atoms and in particular is a 2-ethylhexyl radical or other branched material.

The value O is an oxygen atom in the structural formula while the value x is referred to as the degree of polymerization or DP indicating the number of sacchraide units in the glycosyl portion of the molecule. Typically, the degree of polymerization on average will be between 1 and about 18; preferably from about 1 to about 15; and most preferably from about 1.2 to about 4. Where a powdered or polverant product is preferred it is often desired to utilize the material where the DP is substantially 1. The saccharide backbone (glycosyl) as defined herein is the portion (G) of the molecule.

Where desired in the present invention the glycosides may contain an alkylene oxide unit such as propylene oxide or ethylene oxide between the hydrophobic moiety (aglycone portion) of the glycoside molecule and the saccharide backbone.

Where it is also desirable, the glycoside may contain pendant alkylene oxide units such as ethylene propylene oxide. A disclosure of the manufacture of such glycosides is found in Ser. No. 06/704,828 filed Feb. 25, 1985 by Roth et al. and herein incorporated by reference. As noted previously, the scope of the present invention is particularly broad based in that glycoside materials over a wide range of values according to the structural formula R(OG).sub.x are useful. It is believed that the lower DP, lower alkyl chain-length materials tend to be rather water insoluble and thus excellent for incorporation in powdered or polverant products whereas the higher DP materials are valuable in that they have substantial emulsification capacity to function as a dispersing agent in the present invention. Generally, as the number of carbon atoms in the aglycone portion of the molecule increases the product becomes less water-soluble, thereby holding the active ingredient on the plant surface.

The active ingredients in the present invention are as follows:
