Abstract

An adjuvant composition for modifying the spray properties of an aqueous pesticide composition contains (a) at least one fatty deposition control agent, and (b)(ii) a liquid medium, one or more hydrotropes, and, optionally one or more surfactants, or (b)(ii) one or more surfactants, and adjuvant compositions for modifying the spray properties of an aqueous pesticide composition contains (c) at least one deposition control agent, and (d)(ii) a liquid medium, one or more hydrotropes, and, optionally one or more surfactants, or (d)(ii) one or more surfactants, and use thereof in agricultural applications.

First claim

What is claimed is:

1 . A method for improving deposition control of an aqueous pesticide composition during a spray application, comprising:
contacting an aqueous pesticide composition with an adjuvant composition, wherein the adjuvant composition comprises: (a) at least one fatty deposition control agent, and (b)(ii) a liquid medium, one or more hydrotropes, and, optionally one or more surfactants, or (b)(ii) one or more surfactants, optionally, one or more hydrotropes or a liquid medium, and wherein the adjuvant composition forms a stable emulsion upon dilution into the pesticide composition; and spray applying the aqueous pesticide composition and adjuvant composition to a target pest and/or to the environment of the target pest, wherein the spray applied aqueous pesticide composition exhibits improved deposition control compared to an analogous spray applied aqueous pesticide composition that lacks the adjuvant composition.

2 . The method of claim 1 wherein the adjuvant composition comprises at least one fatty deposition control agent and at least one surfactant.

3 . The method of claim 1 wherein the pesticide comprises one or more herbicide compounds selected from glyphosate, its water soluble salts and esters, and mixtures thereof.

4 . The method of claim 1 wherein the fatty deposition control agent comprises one or more fatty alkanes, fatty amines, fatty acids, fatty amides, fatty glycerides, fatty triglycerides, fatty acid esters, or a mixture thereof.

5 . The method of claim 2 wherein the fatty deposition control agent comprises one or more fatty acids.

6 . The method of claim 5 wherein the fatty acid comprises oleic acid, linoleic acid, tall oil fatty acid or mixtures thereof.

7 . The method of claim 5 wherein the at least one surfactant is selected from polyalkoxylated triglycerides.

8 . The method of claim 1 wherein the fatty deposition control agent comprises one or more fatty triglycerides and wherein the at least one surfactant is present and is selected from polyalkoxylated triglycerides, fatty acid glycol ester surfactants, or a combination thereof.

9 . The method of claim 1 wherein the fatty deposition control agent comprises one or more fatty alkanes, fatty amines, fatty acids, fatty amides, fatty gylcerides, fatty triglycerides, fatty acid esters, or a mixture thereof, provided that if the pesticide is a mixture comprising glyphosate or a water soluble salt or ester of glyphosate and one or more auxinic herbicides, then the fatty deposition control agent is not a fatty amine compound according to formula (I):
R 1 -(A) n   (I)

wherein:
A is —N(R 2 )R 3 ,
R 1 is linear or branched (C 12 -C 18 )alkyl,
R 2 and R 3 are each independently (C 1 -C 6 )alkyl, and

n is 1.

10 . The method of claim 8 wherein the one or more fatty triglycerides are present in an amount ranging from 70% to 99% by weight of the adjuvant composition.

11 . The method of claim 1 wherein the adjuvant composition comprises:
(a) at least one fatty deposition control agent comprising one or more fatty acid esters and
(b)(ii) one or more surfactants selected from alkoxylated alcohol surfactants.

12 . The method of claim 11 wherein the fatty acid ester is a methyl ester of lauric acid.

13 . The method of claim 1 wherein the spray applied aqueous pesticide composition exhibits improved drift control properties compared to an analogous spray applied aqueous pesticide composition that lacks the adjuvant composition.

14 . The method of claim 1 wherein the spray applied aqueous pesticide composition exhibits improved anti-rebound properties compared to an analogous spray applied aqueous pesticide composition that lacks the adjuvant composition.
