Abstract

The invention relates to a synergistic herbicide composition and an application method thereof and in particular relates to a synergistic herbicide composition which is prepared through ternary combination of pendimethalin, oxyfluorfen and oxadiazon and is applied to corn fields. The synergistic herbicide composition comprises active ingredients including (a) N-(1-ethylpropyl)-2,6-binitro-3,4-dimethylaniline, (b) 2-chloro-4-trifluoromethylphenyl-3'-ethoxy-4'-nitrophenyl ether and (c) 5-tert-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-dioxazoline-2-ketone, wherein the weight ratio of (a) to (b) to (c) is (1-50):(1-50):(1-50). The synergistic herbicide composition has a beneficial effect on controlling weeds in the peanut fields, effectively controls annual grassy and broadleaf weeds in the peanut fields, effectively controls generation of weeds with resistance, and simultaneously can reduce the overall use cost and expand the weed control spectrum.

Description

technical field [0001] The present invention relates to a synergistic herbicidal composition and its application method, in particular to a synergistic composition comprising pendimethalin, oxyfluorfen and oxadiazone, which is applied to the corn field. Herbicidal composition. Background technique [0002] Peanut is a major oil crop, mainly distributed in Asia, Africa and America. China and India are the world's largest and second largest peanut producers respectively. my country's current planting area is more than 2.9 million hectares, accounting for 27% of the total area of ​​oil crops. Among them, Henan, Shandong, Hebei, and northern Jiangsu have larger planting areas. The distribution of peanuts in my country is very wide, but mainly concentrated in Shandong, Henan, Hebei, Anhui and other provinces, accounting for more than 60% of the national peanut production. [0003] Peanut According to the survey, there are more than 70 species of weeds in 26 families. Among th...
