Herbicidal composition and application thereof

Abstract

The invention relates to a compound herbicide containing bentazone, methyl-4-chlorophenoxyacetic acid and triclopyr or fluroxypyr. The compound herbicide is characterized by comprising main effectiveingredients A, B and C, wherein A is bentazone, B is methyl-4-chlorophenoxyacetic acid and C is triclopyr or fluroxypyr; the weight ratio of A, B and C is (1-100):(1-100):(1-100), preferably, (1-60):(1-50):(1-20) and more preferably, (1-50):(1-20):(1-20). The compound herbicide is used for controlling sedge weed and broadleaf weed for treatment of post-emergence stems and leaves in paddy fields, sugarcane fields, uncultivated areas and the like.

Description

Technical field: [0001] The invention belongs to the technical field of pesticide compounding, and relates to a compound herbicide containing bentazone, dimethyltetrachloride, triclopyr or fluroxypyr, which is used for post-emergence stem and leaf treatment of rice fields, sugarcane seedlings, non-cultivated land, etc. Control Cyperaceae and broadleaf weeds. technical background: [0002] Chemical weeding is one of the main means of controlling field weeds. However, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance; at the same time, due to the complex grass phase and various types of weeds in the field, the use of a single herbicide species has been unable to effectively control field weeds. weeds. Through the screening of compound formulas of different herbicide varieties, a reasonable formula can be screened out, which can effectively improve the actual control effect on weeds, expand the herbicidal spectrum, reduce the ...
