Abstract

The invention relates to a water dispersible granule formulated from phytocide fluroxypyr and ethoxysulfuron and a preparation method of the granule, belonging to the technical field of pesticides. The water dispersible granule is formulated from the following components of mass percent: 5-30% of fluroxypyr, 5-30% of ethoxysulfuron, 1-8% of dispensing agent, 1-15% of wetting agent, 1-15% of disintegrating agent, 0.1-3% of binding agent and the balance of carrier. The water dispersible granule has the advantages of good dispersibility, fine wettability, high suspensibility, quick disintegrating speed, easy packaging and storage and no dust pollution during production and the like. The water dispersible granule further widens the insecticidal spectrum and is not only capable of effectively preventing and removing nutgrass flatsedge and annual broadleaf weeds in paddy fields, but also applicable to preventing and removing various broadleaf weeds in fields of wheat, barley, maize and other crops of the grass family. The water dispersible granule reduces agricultural cost and is safe to afterreap crop.

Description

technical field [0001] The invention relates to a water-dispersible granule compounded by the herbicide fluroxypyr and ethoxysulfuron-methyl and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Sulfonylurea herbicides are currently the largest class of herbicides with unique effects in the world. They can be used for a variety of broad-leaved weeds and some grass weeds in farmland, woodland and non-cultivated land. At the same time because of its low dosage (10~40g / hm 2 ), low toxicity to mammals, and unique herbicidal activity are widely used. The residual length of sulfonylurea herbicides in the soil is mainly determined by the characteristics of the compound itself and product quality, and is also subject to dosage, soil Characteristics (soil PH value, soil type), application period, spray quality, temperature and humidity and other factors. Take a cautious attitude towards the promotion of long-residual herbici...
