Abstract

The present invention relates to a concentrate, comprising:
a) 100 to 400 g/l of a dinitroaniline; b) 5 to 100 g/l of an imidazolinone ammonium salt or substituted ammonium salt; c) 20 to 100 g/l of water; d) 15 to 150 g/l of an anionic surface-active substance which has at least one sulfonic acid group; e) 5 to 100 g/l of a polymeric, nonionic surface-active substance which has at least one polyethylene oxide group and at least one radical selected from poly-C 3 -C 4 -alkylene oxide groups; f) 50 to 250 g/l of a nonionic surface-active substance selected from ethoxylated fatty acid esters of polyhydroxyl compounds, alkyl polyglucosides, ethoxylated C 4 -C 16 -alkylphenols and ethoxylated C 8 -C 22 -alkanols; g) a hydrocarbon solvent ad 1 l;
where the quantitative data of components a) to f) in g/l are based on the total volume of the active ingredient concentrate.

First claim

The invention claimed is:

1. A liquid, water-emulsifiable active ingredient concentrate comprising the following constituents:
a) 100 to 400 g/l of at least one herbicidal dinitroaniline, where the herbicidal dinitroaniline is pendimethalin;
b) 5 to 100 g/l of at least one imidazolinone herbicide, where the herbicidal imidazolinone herbicide is imazamox, in the form of its ammonium salt or substituted ammonium salt;
c) 20 to 100 g/l of water;
d) 15 to 150 g/l of at least one anionic surface-active substance which is selected from sodium and ammonium salts of C 4 -C 20 -alkylbenzenesulfonic acids, of C 8 -C 22 -alkylsulfuric acid half-esters and of mono- and di-C 4 -C 18 -alkyl esters of sulfosuccinic acid and mixtures thereof;
e) 5 to 100 g/l of at least one polymeric, nonionic surface-active substance which is selected from ethylene oxide-co-propylene oxide block copolymers;
f) 100 to 250 g/l of at least one nonionic surface-active substance selected from ethoxylated fatty acid esters of polyhydroxyl compounds, alkyl polyglucosides, ethoxylated C 4 -C 16 -alkylphenols and ethoxylated C 8 -C 22 -alkanols; and
g) at least one hydrocarbon solvent up to 1 L;
where the quantitative data of components a) to f) in g/l are based on the total volume of the active ingredient concentrate.

2. The active ingredient concentrate according to claim 1 , where the weight ratio of constituent a) to constituent b) is in the range from 2:1 to 50:1.

3. The active ingredient concentrate according to claim 1 , where component d) is selected from the ammonium salts of C 4 -C 20 -alkylbenzenesulfonic acids.

4. The active ingredient concentrate according to claim 1 , where constituent e) has a number-average molecular weight in the range from 1500 to 100000 Daltons.

5. The active ingredient concentrate according to claim 1 , where the weight ratio of constituent d) to constituent e) is in the range from 20:1 to 1:5.

6. The active ingredient concentrate according to claim 1 , in which constituent f) is selected from ethoxylated sorbitan fatty acid esters.

7. The active ingredient concentrate according to claim 1 , where constituent g) is selected from alkylaromatics.

8. The active ingredient concentrate according to claim 1 , comprising less than 200 ppm of polyvalent metal cations.

9. The active ingredient concentrate according to claim 1 , additionally comprising at least one inorganic buffer.

10. The active ingredient concentrate according to claim 1 , where constituents a) to g) constitute at least 99% by weight of the active ingredient concentrate.

11. A method of controlling undesired plant growth comprising treating the plant or a locus where the plant may grow, prior to or after emergence, with the concentrate of claim 1 and an additive or a diluent.

12. The method of claim 11 , where the herbicidal dinitroaniline is pendimethalin.

13. The method of claim 11 , where the herbicidal imidazolinone herbicide is imazamox.

14. The method of claim 11 , where the weight ratio of constituent a) to constituent b) is in the range from 2:1 to 50:1.

15. The method of claim 11 , where component d) is selected from sodium and ammonium salts of C 4 -C 20 -alkylbenzenesulfonic acids, of C 8 -C- 22 -alkylsulfuric acid half-esters and of mono- and di-C 4 -C 18 -alkyl esters of sulfosuccinic acid and mixtures thereof.

16. The method of claim 15 , where component d) is selected from the ammonium salts of C 4 -C 20 -alkylbenzenesulfonic acids.
