Abstract
Homogeneous herbicidal compositions were prepared by dissolving a water-insoluble ester of fluroxypyr or triclopyr in an aqueous solution of an alkali metal or amine salt of an herbicidal acid, such as 2,4-D, MCPA, or dicamba.
Claims13
A herbicidal composition which is a stable, homogeneous aqueous solution concentrate comprising a herbicidal salt and a dissolved water-insoluble herbicide wherein the herbicidal salt is about 15 to about 80 percent by weight of the composition and is a sodium, potassium, ammonia, dimethylamine, diethylamine, triethylamine, monoethanolamine, diethanolamine, or triethanolamine salt of 3,6-dichloro-2-methoxybenzoic acid (dicamba);
- 2,4-dichlorophenoxyacetic acid (2,4-D);
- 2-methyl-4-chloro-phenoxyacetic acid (MCPA);
- 2-(2-methyl-4-chlorophenoxy)propionic acid (CMPP, mecoprop);
- 2-(2,4-dichlorophenoxy)propionic acid (2,4-DP);
- 4-(2-methyl-4-chlorophenoxy)butyric acid (MCPB);
- 4-(2,4-dichlorophenoxy)butyric acid (2,4-DB);
- or ((3,5,6-trichloro-2-pyridinyl)oxy)acetic acid (triclopyr) and the water-insoluble herbicide is about 2.5 to about 40 percent by weight of the composition and is a C.sub.6 -C.sub.12 alkanol or C.sub.6 -C.sub.12 alkoxyalkanol ester of fluroxypyr or triclopyr or 1-(1-(1-butoxy-2-propoxy)-2-propoxy)-2-propyl ester of fluroxypyr which is a liquid at 25.degree. C. and wherein the weight ratio of water-insoluble herbicide to herbicidal salt is about 1:12 to about 1:1;
- and wherein the composition contains essentially no water-miscible or water-immiscible co-solvent.
