Abstract

The invention discloses a pesticide composition and an application thereof. The pesticide composition contains an active ingredient, wherein the active ingredient comprises pinoxaden, fluroxypyr-meptyl and mefenpyr-diethyl, and the weight ratio of pinoxaden to fluroxypyr-meptyl to mefenpyr-diethyl is 1:(0.01-90):(0.01-90); and the application refers to the application of the pesticide composition to prevention and control of crop farmland weeds, a crop refer to wheat, and the weeds comprises at least one of wild oats, ryegrass, green bristlegrass herbs, amur foxtail, Sclerochloa dura, beckmannia syzigachne, Polypogon fugax, phalaris arundinacea, cleavers, Descurainia, capsella bursa-pastoris, stellaria media, polygonum, field bindweeds and Vicia sativa L. By using the pesticide composition disclosed by the invention, wheat farmland weeds can be effectively prevented and controlled, and the yield of wheat can be increased.

Description

technical field

[0001] The present disclosure relates to the technical field of pesticides, in particular to a pesticide composition and its application. Background technique

[0002] Wheat is the main food crop grown in my country, including wheat (winter wheat and spring wheat), barley (winter barley and spring barley), rye and barley (highland barley). Field weeds compete with wheat for water, fertilizer, and sunlight, which is one of the main factors affecting wheat yield. If it is not controlled, it will cause a large reduction in wheat yield. The main weeds that harm the wheat fields are: wild oats, ryegrass, foxtail, apricot, hard grass, oystergrass, clubhead grass, scorpion grass, cattail, wormwood, shepherd's purse, chickweed, Polygonum, field spinach Flowers, large nest vegetables, etc. And the damage is the greatest at the seedling stage, which can cause dwarfing of wheat plants, thin stems and yellow leaves, etc., and seriously affect the yield of wheat, and th...
