Abstract

The invention relates to a herbicide composition, which contains the following active ingredients in part by weight: 0.5 to 95 parts of cyhalofop-butyl and 0.5 to 95 parts of metamifop. 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 weeding effect of the herbicide composition is remarkably improved compared with a single agent; and the herbicide composition shows extremely good synergistic effect, reduces the consumption of the agents, reduces the influence on the environment at the same time of reducing the medicament cost of peasants, meanwhile, enlarges the weeding spectrum, and can effectively delay the occurrence and development of single agent resistance.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide composition containing two active components of cyhalofop-ethyl and fenoxazone and its application. 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 inactive to acetyl-CoA carboxylase, so cyhalofop-me...
