Abstract

Liquid adjuvant compositions, which comprise a polysaccharide, alkali metal bicarbonate, potassium sulfate and a dispersant, as well as methods of making and applications thereof.

First claim

What is claimed is:

1 . An adjuvant composition comprising, by weight of composition:
from about 25 wt % to about 75 wt % of an alkali metal bicarbonate; from about 15 wt % to about 50 wt % of potassium sulfate; from about 0.01 wt % to about 15 wt % of a drift reduction agent comprising at least one polysaccharide or at least one derivatized polysaccharide; and from about 0.01 wt % to about 10 wt % of a dispersant, wherein the adjuvant composition is dispersed in a liquid medium.

2 . The composition of claim 1 further comprising a water-soluble nitrogen-containing fertilizer.

3 . The composition of claim 1 wherein the at least one derivatized polysaccharide is hydroxypropyl guar or carboxymethylhydroxypropyl guar.

4 . The composition of claim 1 wherein the at least one derivatized polysaccharide is hydroxypropyl guar, carboxymethyl guar, hydroxypropyl trimethylammonium guar, hydroxypropyl lauryldimethylammonium guar or hydroxypropyl stearyldimethylammonium guar.

5 . The composition of claim 1 further comprising an antifoam agent.

6 . The composition of claim 1 wherein the dispersant is a salt of polycarboxylic acid.

7 . The composition of claim 1 wherein the alkali metal bicarbonate is sodium bicarbonate.

8 . The composition of claim 1 wherein the alkali metal bicarbonate is present in an amount from about 35 wt % to about 60 wt %.

9 . The composition of claim 1 wherein the potassium sulfate is present in an amount from about 20 wt % to about 50 wt %.

10 . The composition of claim 1 wherein the composition is free or substantially free of ammonium-containing compounds.

11 . A method for preparing a pesticide composition comprising the steps of contacting an adjuvant composition with an effective amount of a pesticide and water, wherein the adjuvant composition comprises, by weight of adjuvant composition:
i. from about 25 wt % to about 75 wt % of an alkali metal bicarbonate; ii. from about 15 wt % to about 50 wt % of potassium sulfate; iii. from about 0.01 wt % to about 15 wt % of a drift reduction agent comprising at least one polysaccharide or at least one derivatized polysaccharide; and iv. from about 0.01 wt % to about 10 wt % of a dispersant.

12 . The method of claim 11 further comprising a water-soluble nitrogen-containing fertilizer.

13 . The method of claim 11 wherein the at least one derivatized polysaccharide is hydroxypropyl guar or carboxymethylhydroxypropyl guar.

14 . The method of claim 11 wherein the at least one derivatized polysaccharide is hydroxypropyl guar, carboxymethyl guar, hydroxypropyl trimethylammonium guar, hydroxypropyl lauryldimethylammonium guar or hydroxypropyl stearyldimethylammonium guar.

15 . The method of claim 11 further comprising an antifoam agent.

16 . The method of claim 11 wherein the dispersant is a salt of polycarboxylic acid.

17 . The method of claim 11 wherein the alkali metal bicarbonate is sodium bicarbonate.

18 . The method of claim 11 wherein the alkali metal bicarbonate is present in an amount from about 35 wt % to about 60 wt %.

19 . The method of claim 11 wherein the potassium sulfate is present in an amount from about 20 wt % to about 50 wt %.
