Abstract:
1. A herbicidal concentrate composition comprising a mixture of the monomethylamine and dimethylamine salts of clopyralid, wherein the mixture of clopyralid salts is present in aqueous solution at a concentration of at least 300 g/L, based on herbicidal acid equivalent and the mole ratio of dimethylamine (DMA) to monomethylamine (MMA) is in the range of from 70%-90% DMA to 30%-10% MMA; wherein the herbicidal concentrate composition comprising the DMA salt of clopyralid and the MMA salt of clopyralid has enhanced stability and reduced crystal growth at cold temperatures compared to an equivalent herbicidal concentrate where the DMA salt of clopyralid is present while the MMA salt of clopyralid is absent or the MMA salt of clopyralid is present while the DMA salt of clopyralid is absent.
