Abstract

The present invention relates to liquid suspension concentrate formulations for plant protection comprising: 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethy)amino]sulfonyl]benzamide in the form of the anhydrate; N-(phosphonomethyl)glycine in the form of its free acid, in the form of the ammonium salt or a substituted ammonium salt or a mixture thereof; at least one diluent selected from: hydrocarbon solvents having a boiling point of at least 100° C.; and —C 1 -C 8 -alkyl esters of C 8 -C 26 -fatty acids, mono- and di-C 1 -C 4 -alkyl amides of C 8 -C 26 -fatty acids; optionally at least one diluent that differs from diluents c) and that is selected from organic solvents having at least one oxygen atom; at least one non-ionic surfactant comprising a polyalkoxylate moiety; and at least one anionic surfactant containing a sulfonate group or a sulfate group.

First claim

The invention claimed is:

1. A liquid suspension concentrate formulation for plant protection, comprising the components:
a) 1 to 8% 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)amino]sulfonyl]benzamide in the form of the anhydrite;
b) 28 to 37% N-(phosphonomethyl)glycine in the form of its free acid, in the form of the ammonium salt or a substituted ammonium salt, or a mixture thereof;
c) 30 to 55% at least one diluent selected from the group consisting of:
c1) hydrocarbon solvents having a boiling point of at least 100° C.; and
c2) C 1 -C 8 -alkyl esters of C 8 -C 26 -fatty acids, mono-, or di-C 1 -C 4 -alkyl amides of C 8 -C 26 -fatty acids;

d) 0 to 20% optionally at least one additional diluent that differs from the at least one diluent c) and is selected an organic solvent having at least one oxygen atom;
e) 3 to 20% at least one non-ionic surfactant comprising a polyalkoxylate moiety; and
f) 2 to 22% at least one anionic surfactant containing a sulfonate group or a sulfate group; wherein the % of the components are based on the total weight of the formulation.

2. The liquid suspension concentrate formulation of claim 1 , wherein the component b) is glyphosate ammonium salt.

3. The liquid suspension concentrate formulation of claim 1 , wherein the weight ratio of component a) to component b) is in the range of from 1:3 to 1:16.

4. The liquid suspension concentrate formulation of claim 1 , wherein the at least one additional diluent d) is selected from the group consisting of C 4 -C 15 -dialkyl dicarboxylic acid esters, N-C 8 -C 15 -alkyl pyrrolidones, C 2 -C 6 -lactones and DMSO.

5. The liquid suspension concentrate formulation of claim 1 , wherein the one or more non-ionic surfactants of component e) are selected from the group consisting of polyethoxylates of C 8 -C 22 -alkanols and polyethoxylates of vegetable oils or animal fats.

6. The liquid suspension concentrate formulation of claim 5 , wherein the component e) comprises at least two different non-ionic surfactants.

7. The liquid suspension concentrate formulation of claim 5 , wherein the component e) comprises at least one polyethoxylate of a C 8 -C 22 -alkanol and at least one polyethoxylate of a vegetable oil.

8. The liquid suspension concentrate formulation of claim 5 , wherein the one or more anionic surfactants of component f) are selected from the group consisting of polyethoxylates of mono-, di- and tristyrylphenylether sulfates, C 1 -C 16 -alkylbenzene sulfonates, C 1 -C- 16 -alkynaphthalene sulfonates and C 4 -C 18 -dialkyl sulfosuccinates.

9. The liquid suspension concentrate formulation of claim 8 , wherein the component f) comprises at least two different anionic surfactants.

10. The liquid suspension concentrate formulation of claim 1 , wherein the hydrocarbon solvents c1) have a boiling point in the range of from 170 to 310° C.

11. The liquid suspension concentrate formulation of claim 1 , wherein the at least one diluent c2) are selected from C 1 -C 8 -alkyl esters of C 8 -C 26 -fatty acids and di-C 1 -C 4 -alkyl amides of C 8 -C 26 -fatty acids.

12. The liquid suspension concentrate formulation of claim 1 , wherein the at least one diluent c) is selected from hydrocarbon solvents c1).

13. The liquid suspension concentrate formulation of claim 1 , wherein the at least one diluent c) is selected from C 1 -C 8 -alkyl esters of C 8 -C 26 -fatty acids, mono-, and di-C 1 -C 4 -alkyl amides of C 8 -C 26 -fatty acids.

14. The liquid suspension concentrate formulation of claim 1 , wherein the component c) comprises at least one diluent c1) and at least one diluent c2).

15. A method of controlling undesired vegetation, comprising applying the liquid suspension concentrate formulation of claim 1 , undiluted or in the form of an aqueous dilution, to plants, their environment or on seeds.

16. The method of claim 15 , wherein the component b) of the formulation is glyphosate ammonium salt.

17. The method of claim 15 , wherein the weight ratio of component a) to compound b) of the formulation is in the range of from 1:3 to 1:16.

18. The method of claim 15 , wherein the at least one additional diluent d) of the formulation is selected from the group consisting of C 4 -C 15 -dialkyl dicarboxylic acid esters, N- 5 -C 15 -alkyl pyrrolidones, C 2 -C 6 -lactones and DMSO.

19. The method of claim 15 , wherein the one or more non-ionic surfactants of component e) of the formulation are selected from the group consisting of polyethoxylates of C 8 -C 22 -alkanols and polyethoxylates of vegetable oils or animal fats.
