Agricultural pesticide compositions

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 consists of:

at least one fatty deposition control agent comprising tall oil fatty acid, and

at least one surfactant comprising an ethoxylated castor oil surfactant and

optionally a liquid medium, and

optionally a C8-C14 alcohol ethoxylate surfactant that is alkoxylated with 2 to 50 ethoxy units per alcohol ethoxylate molecule;

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 applying uses an air induction nozzle or a flat fan nozzle and wherein droplets comprising the aqueous pesticide composition and the adjuvant composition have greater than 60% of the droplets in the 150 to 500 μm range exiting the nozzle when the flat fan nozzle is used and greater than 70% of the droplets in the 150 to 500 μm range exiting the nozzle when the air induction nozzle is used,

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

(ii).

2. The method of claim 1 , wherein the at least one fatty deposition control agent is present at least at 9 wt % of the adjuvant composition and the at least one surfactant is present at least at 1 wt % of the adjuvant composition.

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 further comprises a vegetable oil.

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

7. The method of claim 5 , wherein the at least one surfactant is selected from the group consisting of polyethoxylated castor oils, and polyethoxylated-propoxylated castor oils, ethoxylated castor oil oleate, and ethoxylated castor oil trilaurate.

8. 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.

9. 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.

10. The method of claim 1 , wherein the adjuvant composition comprises the fatty acid deposition control agent in an amount ranging from 10% to 95% by weight of composition.

11. The method of claim 1 , wherein the adjuvant composition comprises the fatty acid deposition control agent in an amount ranging from 70% to 90% by weight of composition.

12. The method of claim 1 , wherein the adjuvant composition comprises the fatty acid deposition control agent in an amount ranging from 60% to 90% by weight of composition.

13. The method of claim 1 , wherein the adjuvant composition comprises the fatty acid deposition control agent in an amount ranging from 80% to 95% by weight of composition.

14. The method of claim 1 , wherein the adjuvant composition comprises the surfactant in an amount ranging from 5% to 50% by weight of composition.

15. The method of claim 1 , wherein the adjuvant composition comprises the surfactant in an amount ranging from 7% to 20% by weight of composition.

16. The method of claim 1 , wherein the adjuvant composition comprises the one or more surfactants in an amount ranging from 10% to 40% by weight of composition.

17. The method of claim 1 , wherein the adjuvant composition comprises the one or more surfactants in an amount ranging from 5% to 25% by weight of composition.

18. The method of claim 1 , wherein the adjuvant composition comprises the one or more surfactants in an amount ranging from 20% to 35% by weight of composition.

19. The method of claim 1 , wherein the C8-C14 alcohol ethoxylate surfactant that is alkoxylated with 2 to 50 ethoxy units per alcohol ethoxylate molecule is present in the adjuvant composition.

20. The method of claim 1 , wherein the one or more surfactants is present at 10 wt % of the adjuvant composition.

21. 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 consists of:

at least one fatty deposition control agent comprising tall oil fatty acid, and one or more surfactants comprising an ethoxylated castor oil surfactant, and optionally a liquid medium,

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 applying uses an air induction nozzle or a flat fan nozzle and wherein droplets comprising the aqueous pesticide composition and the adjuvant composition have greater than 60% of the droplets in the 150 to 500 μm range exiting the nozzle when the flat fan nozzle is used and greater than 70% of the droplets in the 150 to 500 μm range exiting the nozzle when the air induction nozzle is used,
