Abstract

The invention relates to a herbicide composition, which contains the following active ingredients in part by weight: 0.1 to 33 parts of penoxsulam and 0.1 to 99 parts of metamifop. The invention also relates to application of the herbicide composition in preventing and controlling annual and perennial broadleaf weeds and grass weeds in paddy fields. Compared with single agent, the herbicide composition has the advantages that weeding effect is remarkably improved, extremely good synergy is shown, the using amount of agents, influence on the environment, and the agent cost of peasants are reduced; and meanwhile, the herbicide composition 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 penoxsulam and fenoxen and its application. Background technique [0002] Penoxsulam (penoxsulam) is a post-emergence herbicide developed by Dow AgroSciences in the United States, belonging to the triazolopyrimidine sulfonamide herbicide, which acts by inhibiting acetolactate synthase (ALS). effect. [0003] Metamifop is an aryloxyphenoxy ester (AOPP) herbicide, which can inhibit ACC enzyme and promote plant fatty acid synthesis. As an acetyl coenzyme A carboxylase (ACCase) inhibitor, it can control most annual grass weeds very well. Unlike most AOPP herbicides, fenpyramid is safe for rice and can Effectively control the main weeds in paddy fields, such as barnyardgrass, stephenia, crabgrass and goosegrass, and are mainly used for weeding in transplanted and direct-seeded paddy fields. [0004] However, the comb...
