Problems solved by technology

[0005] However, the above three herbicides used alone have a general control effect on annual and perennial broad-leaved weeds and grass weeds in paddy fields, and cannot achieve the optimal herbicidal effect.

Abstract

The invention relates to a herbicide composition, which comprises the following active components in parts by weight: 1 to 20 parts of cyhalofop-butyl, 1 to 20 parts of metamifop and 1 to 60 parts of quinclorac or salt thereof. The invention also relates to application of the herbicide composition in preventing and controlling annual and perennial broadleaf weeds and gramineous weeds of paddy fields. The herbicide composition has much higher weeding effect compared with a single dose, shows great synergistic effect, reduces the drug amount, lowers the drug cost for farmers and reduces influence on environment; meanwhile, the herbicide composition expands the herbicide control spectrum and effectively delays the occurrence and development of single dose resistance.

Description

technical field [0001] The present invention relates to the field of agricultural herbicides, in particular to a herbicide composition containing three active components of cyhalofop-ethyl, fenfluramid, quinclorac or a salt thereof and an application thereof. Background technique [0002] Cyhalofop-ethyl is the only aryloxyphenoxypropionic acid herbicide with high safety to rice. Cyhalofop-ethyl is a systemic conductive herbicide, which is absorbed by the leaves and sheaths of plants, conducted by phloem, and accumulated in the meristem area of ​​plants, inhibiting acetyl-CoA carboxylase, stopping fatty acid synthesis, and cell growth The division cannot be carried out normally, the membrane system and other lipid-containing structures are destroyed, and finally the plant dies. The speed of action of cyhalofop-ethyl is relatively slow, and it generally takes 1 to 3 weeks to kill the weeds. In rice, cyhalofop-methyl can be rapidly degraded into a diacid state that is inacti...
