High-strength, low viscosity herbicidal concentrate of clopyralid dimethylamin
View Patent ↗This invention relates to a high-strength, aqueous herbicidal concentrate containing the clopyralid dimethylamine salt. The formulation is stable to storage and exhibits lower viscosity than other clopyralid amine salt formulations.
1. A high-strength herbicidal aqueous concentrate comprising: (a) water and (b) clopyralid dimethylamine, in solution in the water, wherein the concentrate contains 600 gae/L to 850 gae/L of the clopyralid dimethylamine.
2. The concentrate of claim 1 having a viscosity less than about 50 centipoise at 5° C.
3. A method of controlling undesirable vegetation which comprises applying to the vegetation a water-diluted composition of claim 1 .
4. A composition comprising:
(a) water;
(b) clopyralid;
(c) dimethylamine;
wherein said clopyralid and said dimethylamine are dissolved in the water; and
wherein said clopyralid is provided in the composition in an amount from 600 to 850 gae/L of the composition.
5. The composition of claim 4 wherein said clopyralid is provided in the composition in an amount of 630 gae/L of the composition.
6. The composition of claim 4 wherein said clopyralid is provided in the composition in an amount of from 783 to 850 gae/L of the composition.
7. The concentrate of claim 4 that remains a clear solution at 0° C., has a viscosity less than about 50 centipoise at 5° C., and is stable at 40° C.
