Abstract

Agricultural compositions comprising a non-pesticide choline salt or a non-ammonium water conditioning agent, optionally, a polysaccharide, optionally, a dispersant or surfactant, and optionally, water, as well as methods of making and applications thereof.

First claim

What is claimed is:

1. An agricultural composition comprising:
a non-pesticide water conditioning component, wherein the non-pesticide water conditioning component comprises choline salt comprising at least one of the following: choline carbonate, choline sulfate, choline citrate, choline acrylates, choline carboxylates, choline phosphonates, tricholine citrate, tricholine phosphate, choline dihydrogen citrate, or choline bitartrate, wherein the non-pesticide water conditioning component is between 0.4 wt. % and 1 wt. % of the composition based on the total weight of the composition; and
at least one pesticide comprising dicamba or a salt thereof, wherein the dicamba or salt thereof is between 0.005 wt. % and 1 wt. % of the composition based on the total weight of the composition; and
optionally, water.

2. The agricultural composition of claim 1 , further comprising a surfactant.

3. The agricultural composition of claim 1 , wherein the pesticide is a combination of:
(i) dicamba or a salt thereof; and
(ii) glyphosate or a salt thereof.

4. The agricultural composition of claim 1 , wherein the agricultural composition comprises less than about 1 wt. % of ammonium-containing compounds based on the total weight of the composition.

5. An agricultural composition effective at controlling plant pests or controlling plant growth in combination with a pesticidally effective amount of a pesticide comprising:
a water conditioning component comprising choline salt comprising at least one of the following: choline bicarbonate, choline carbonate, choline sulfate, choline citrate, choline acrylates, choline carboxylates, choline phosphonates, tricholine citrate, tricholine phosphate, choline dihydrogen citrate or choline bitartrate, wherein the water conditioning component is at least 5 wt. % and up to and including 90 wt. % of the composition based on the total weight of the composition; and
a drift reduction agent comprising at least one polysaccharide, at least one derivatized polysaccharide or a combination thereof, wherein the drift reduction agent is present in an amount from 0.01 wt % to about 15 wt % by weight of the composition based on the total weight of the composition; and
a dispersant or surfactant, wherein the dispersant or surfactant is present in an amount from about 0.01 wt % to about 50 wt % by weight of the composition based on the total weight of the composition; and
optionally, water,
wherein the at least one derivatized polysaccharide is hydroxypropyl guar, carboxymethylhydroxypropyl guar; carboxymethyl guar, hydroxypropyl trimethylammonium guar, trimethylammonium guar, hydroxypropyl lauryldimethylammonium guar or hydroxypropyl stearyldimethylammonium guar.

6. The agricultural composition of claim 5 , wherein the at least one derivatized polysaccharide is hydroxypropyl guar or carboxymethylhydroxypropyl guar.

7. The agricultural composition of claim 5 , wherein the at least one derivatized polysaccharide is hydroxypropyl guar, carboxymethyl guar, hydroxypropyl trimethylammonium guar, trimethylammonium guar, hydroxypropyl lauryldimethylammonium guar or hydroxypropyl stearyldimethylammonium guar.

8. The agricultural composition of claim 5 , wherein the dispersant is a salt of polycarboxylic acid.

9. The agricultural composition of claim 5 , wherein the water conditioning component is present in an amount from about 10 wt % to about 50 wt %, by weight of the composition.

10. The agricultural composition of claim 5 , wherein the water conditioning component is present in an amount from about 20 wt % to about 40 wt %, by weight of the composition.

11. The agricultural composition of claim 5 , wherein the composition is free or substantially free of ammonium-containing compounds.

12. A method for preparing a pesticide composition comprising the steps of:
contacting the agricultural composition of claim 5 with a pesticide comprising dicamba or a salt thereof to form a pesticide formulation.

13. The method of claim 12 , wherein the one derivatized polysaccharide is cationic hydroxypropyl guar or cationic guar.

14. The agricultural composition of claim 5 , wherein the agricultural composition comprises less than about 1 wt. % of ammonium-containing compounds based on the total weight of the composition.

15. The agricultural composition of claim 5 , further comprising a water-soluble nitrogen-containing fertilizer.

16. The agricultural composition of claim 5 , further comprising a pesticide.

17. The agricultural composition of claim 5 , wherein the choline salt is at least one of the following: choline bicarbonate, choline carbonate, choline sulfate, choline citrate, choline acrylates, choline carboxylates, choline phosphonates, tricholine citrate, tricholine phosphate, or choline dihydrogen citrate.

18. The agricultural composition of claim 17 , wherein the at least one derivatized polysaccharide is hydroxypropyl guar or carboxymethylhydroxypropyl guar.

19. The agricultural composition of claim 17 , wherein the at least one derivatized polysaccharide is hydroxypropyl guar, carboxymethyl guar, hydroxypropyl trimethylammonium guar, trimethylammonium guar, hydroxypropyl lauryldimethylammonium guar or hydroxypropyl stearyldimethylammonium guar.

20. The agricultural composition of claim 1 , wherein the non-pesticide water conditioning component is between 0.5 wt. % and 1 wt. % of the composition based on the total weight of the composition.
