Abstract

Claims (31)

1. A method for treating seeds comprising applying to said seeds a composition comprising a seed treatment for formulation comprising from about 0.1% to about 80% by weight of at least one active ingredient, about 10% to about 50% by weight of a carrier, about 0.1% to about 20% by weight of at least one surfactant, about 0.1% to about 30% by weight of at least one dispersing agent, at least one pigment or dye, at least one anti-caking agent, and an organosilicone additive of the formula:

wherein:

Z is C 3 H 6 O(C 2 H 4 O) n G;

X is a number from 0 to 30;

Y is a number from 1 to 10;

n is a number from 1 to 50; and

G is hydrogen or an alkyl group of from 1 to 4 carbon atoms.

2. A method for treating seeds comprising applying to said seeds a composition comprising a seed treatment formulation comprising at least one pigment or dye and an organosilicone additive of the formula:

wherein:

X is a number from 0 to 30;

Y is a number from 0 to 10;

each R 1 and R 2 is independently selected from the group consisting of alkyl moieties of from 1 to 18 carbon atoms; provided that, if Y is 0, at least one R 2 is Z;

Z is R 3 OB n G;

R 3 is an alkylene moiety of from 1 to 4 carbon atoms;

B is an alkylene oxide moiety selected firm the group consisting of ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof;

n is a number from 1 to 50 if, and only if, B contains ethylene oxide, otherwise n is a number from 1 to 10; and

G is selected from the group consisting of hydrogen, hydrocarbon moieties of from 1 to 18 carbon atoms, and acetyl.

3. The method of claim 2 wherein the formulation is a water-dispersible paste.

4. The method of claim 2 wherein all R 1 moieties are the same alkyl group.

5. The method of claim 4 wherein at least one R 2 group is the same as R 1 .

6. The method of claim 4 wherein all R 1 moieties are methyl groups.

7. The method of claim 2 wherein R 3 is propylene.

8. The method of claim 2 wherein B is ethylene oxide.

9. The method of claim 7 wherein B is ethylene oxide.

10. The method of claim 2 wherein the silicone additive is of the formula:

wherein Z is C 3 H 6 O(C 2 H 4 O) n G, G is hydrogen or an alkyl group of from 1 to 4 carbon atoms, and Y does not equal zero.

11. The method of claim 2 wherein the seed treatment formulation further comprises at least one ingredient selected from the group consisting of an active agent, a carrier, a surfactant, a dispersing agent, an anti-caking agent, and a foam-control agent.

12. The method of claim 11 wherein the active agent is selected from the group consisting of 5,6-dihydro-2-methyl-1,4-oxathiine-3-carboxanilide 4,4-dioxide; carboxin; 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methyl carbamate; methylcarbamic acid 2-(2-chloro-1-methoxy ethoxy)phenyl ester; 2-(4-chlorophenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)-butan-2-ol; pentachloronitrobenzene; 5-ethoxy-3-(trichloromethyl)-1,2,4-thiadiazole; Rhizobium sp; Penicillium bilajii; Bacillus subtilis ; β-(4-chlorophenoxy)-α-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol; tetramethylthiuram disulfide; 2-(4-thiazolyl)benzimidazole; (2-methyl[1,1′-biphenyl]-3-yl)methyl-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropane-carboxylate; 1,2,3,4,5,6-hexachlorocyclo-hexane, gamma-isomer; N-(2,6-dimethylphenyl)-N-(methoxyacetyl)alanine methyl ester; 1-[(6-chloro-3-pyridinyl)methyl]-N-nitro-2-imidazolidinimine; tebuconazole; and α-butyl-α′-(4-chlorophenyl)-1H-1,2,4-triazole propanenitrile.

13. The method of claim 11 wherein the carrier is a hydrocarbon oil carrier selected from the group consisting of vegetable oil, petroleum-based hydrocarbon oil, paraffinic/naphthenic hydrocarbon oil, mineral oil, and mixtures thereof.

14. The method of claim 11 wherein the surfactant is selected from the group consisting of alkaryl sulfonates, lignin and lignin derivatives, silicone-based surfactants, sulfonates of condensed naphthalenes, sulfonates of dodecyl/tridecyl benzene, sulfonates of naphthalene and alkyl naphthalene, sulfosuccinamates, sulfosuccinates, and mixtures thereof.

15. The method of claim 11 wherein the dispersing agent is selected from the group consisting of block polymers, alkylphenol ethoxylates, ethoxylated alcohols, ethoxylated alkylphenols, polyacrylic acid, propoxylated alkylphenols, sulfonated ethoxylated alkylphenols, lignin and lignin derivatives, tridecyl and dodecyl benzene sulfonic acid, and mixtures thereof.
