Abstract

The invention provides a metamifop water dispersible granule. The granule is prepared from, by weight, 10-30% of metamifop, 2-10% of wetting agent, 2-8% of dispersing agent, 3-6% of organosilicone surface active agent, 0.5-6% of adhesive and the balance filler. The adhesive is a mixture of corn starch and gas-phase silicon dioxide. Metamifop is washed through a sodium bicarbonate solution with concentration of 0.1-0.5 wt% in advance. The water dispersible granule is high in suspension stability, meets the requirements of high-altitude low-temperature regions, and reduces the influences of organic solvent on the environment.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a water-dispersible granule of fenpyramid. Background technique [0002] Fenpyramid (English name metamifop) is a new herbicide developed by Korea Chemical Technology Institute. It belongs to the class of aryloxyphenoxypropionate herbicides. It can control most of the annual grass weeds very well. The difference between these herbicides is that fenpyramid is safe for rice. Mefenpyramid was used at 90-200g / hm after seedling 2 Spraying on transplanted and direct-seeded paddy fields under the condition of active ingredient dosage can effectively control the main weeds in paddy fields, such as barnyardgrass, stephenia, crabgrass and goosegrass. As one of the vicious weeds in paddy fields, D. chinensis has the characteristics of wide occurrence and large amount, and has the tendency of aggravating the damage. The results of the census of weeds in paddy fields from 19...
