Mesotrione-containing weeding composition

Abstract

The invention discloses a mesotrione-containing weeding composition which characterized in that the effective components are compounded from mesotrione, fluoroglycofen-ethyl and paraquat. The weeding composition is prepared from the following components in percentage by weight: 5% of mesotrione, 10% of fluoroglycofen-ethyl, 1% of paraquat, 5% of emulsifier and the balance of solvent. The solvent is selected from xylene or dichloromethane. The emulsifier is selected from one or more of nonylphenol polyethenoxy ether, calcium alkylphenylsulfate and phenethylphenyl polyoxyethylene-polyoxypropylene ether. By mixing the active components of the composition, the advantages of the active components are complemented, the consumptions are reduced, and the composition postpones the generation of the drug resistance of weed and has the advantages of favorable weeding effect, time saving and labor saving.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a compound herbicidal composition containing mesotrione, belonging to the technical field of agrochemicals. Background technique [0002] With the progress of society, in the rural areas of our country, the concept of scientific and technological farming has been deeply rooted in the hearts of the people, and herbicides are widely used. However, long-term or simple use of one or one type of herbicide can easily form an inherent herbicidal spectrum, resulting in a relatively narrow range of weed control, and at the same time it is easy to change the grass phase. After the sensitive weeds are controlled, the drug-resistant ones Weeds are easier to grow. Mesotrione is a systemic selective herbicide, which has good control effect on most broad-leaved weeds and gramineous weeds below the 4-leaf stage, is safe to corn and sugarcane, and has good stem and leaf treatment activity , has the f...
