Agricultural adjuvant compositions, herbicide compositions, and methods for using such compositions
View Patent ↗Pesticide compositions that contain, based on 100 pbw of such composition, (a) greater than or equal to about 0.006 parts by weight of a betaine surfactant, (b) greater than or equal to about 0.02 parts by weight of a humectant selected from polyhydric alcohols, polysaccharide humectants, and mixtures thereof, and (c) an effective amount of a pesticide, exhibit reduced foaming and high efficacy.
1. An adjuvant composition for a pesticide consisting essentially of, based on 100 parts by weight of the adjuvant composition:
(a) greater than or equal to about 1 part by weight of betaine surfactant,
(b) greater than or equal to about 1 part by weight of glycerol, and
(c) optionally, one or more solvents, thickeners, antifoam agents, spreaders, drift control agents, water conditioners, or fertilizers.
2. The composition of claim 1 , wherein the betaine surfactant is selected from (C 12 -C 18 )alkyldimethyl betaine, cocoamidopropyl betaine, and mixtures thereof.
3. The composition of claim 1 , wherein the betaine surfactant comprises (C 12 -C 18 )alkyldimethyl betaine.
4. The adjuvant composition of claim 1 , wherein the amount of surfactant is from 1 to about 30 parts by weight and the amount of glycerol is from about 10 to about 90 parts by weight.
5. The adjuvant composition of claim 1 , wherein the amount of surfactant is from 5 to about 25 parts by weight and the amount of glycerol is from about 10 to about 90 parts by weight.
6. The adjuvant composition of claim 1 , wherein said composition consists of, based on 100 parts by weight of the adjuvant composition:
(a) greater than or equal to about 1 part by weight of betaine surfactant,
(b) greater than or equal to about 1 part by weight of glycerol, and
(c) optionally, one or more solvents, thickeners, antifoam agents, spreaders or drift control agents, water conditioners, or fertilizers.
7. The composition of claim 6 , wherein at least one of said one or more water conditioners comprises ammonium sulfate.
8. The composition of claim 1 , wherein at least one of said one or more water conditioners comprises ammonium sulfate.
9. The composition of claim 8 , wherein said composition comprises greater than 0.1 parts by weight of ammonium sulfate.
