A kind of pesticide composition and its application

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...

Problems solved by technology

[0003] At present, the main herbicidal pesticide varieties used for post-emergence control of field weeds in wheat fields have the disadvantages that their safety is greatly affected by environmental conditions (especially temperature and humidity conditions) and their drift is strong; Grass resistance to pesticides is growing rapidly, and if the amount of use is increased, the risk of injury to wheat seedlings will be high; secondly, the cost of using existing herbicide pesticides is high, and weeds are prone to relapse
