Weeding composition containing metamifop and application thereof

Abstract

The invention discloses a ternary compound weeding composition, and its active ingredients include metamifop, cyhalofop-butyl, and starane, wherein the weight ratio of the metamifop, cyhalofop-butyl, and starane is (1-6):(2-7):(1-6), preferably (2-6):(3-7):(2-6), most preferably 4:5:4; under such weight ratio, the production cost and the weeding effect can be balanced, and good economic and social benefits are brought. The weeding composition is applicable to the prevention and treatment of grassy seeds and broad-leaved weeds for various crops, particularly to the prevention and treatment of Echinochloa crusgalli, Euphorbia lathyris, Monochoria vaginalis and Potamogeton distinctus.

Description

technical field [0001] The invention belongs to the field of weed control in paddy fields, and specifically relates to a herbicidal composition whose active ingredients include fenpyramid, cyhalofop-ethyl and isooctyl fluroxypyr and its application. Background technique [0002] Rice is one of the main crops in my country. With the continuous expansion of its planting area, rice field weed damage is also increasing day by day in the expanding production, and the damage is becoming more and more serious. Whether it can effectively control the rice field weed damage and stabilize the high yield of rice has become an important issue. One of the main subjects of modern agricultural herbicide research. At present, most of the herbicides used in paddy fields have a narrow herbicidal spectrum, and cannot play a very good role on grass weeds, broad-leaved weeds and sedge weeds in the field at the same time. Generally, farmers need to apply twice or even three times. The ideal contro...

Problems solved by technology

However, it is relatively slow from the absorption of cyhalofop-methyl to the death of weeds, generally takes 1-3 weeks

For a long time, the single use of cyhalofop-ethyl produces serious resistance, which leads to an increasing dosage, and the effect of cyhalofop-ethyl on controlling broad-leaved weeds is poor, especially for broad-leaved weeds. The effect of weeds is also poor, such as old barnyardgrass, crabgrass, etc.
