Water soluble granule of MCPA salt and preparation method thereof

摘要

The present invention relates to the technical field of pesticides, and discloses a water soluble granule of 2-methyl-4-chlorophenoxy acetic acid (MCPA) salt and preparation method thereof. The water soluble granule of the present invention consists of the MCPA salt as well as a specific surfactant, a chelator and a filler. A water soluble granule of MCPA salt capable of achieving better storage stability, solubility and dissolving stability as well as persistent foamability in high concentration of hard water is prepared in the present invention by adjusting the adjuvant types of the water soluble granule of MCPA salt and using in combination with proper adjuvants. It is particularly suitable for countries and regions of higher water hardness.
