Abstract

The invention discloses a weeding composition and an application thereof. The weeding composition contains mesotrione, rimsulfuron and the balance of auxiliary elements allowable and receivable in agricultural chemicals, wherein the weight ratio of the mesotrione to the rimsulfuron is 1:50-50:1. After the mesotrione and the rimsulfuron are compounded in definite proportion, the weeding compositionhas a marked synergistic function, and can be used for preventing and weeding grassy weeds and broad leaved weeds in corn fields.

Description

technical field [0001] The invention relates to a herbicidal composition and application thereof, in particular to a binary compound composition containing mesotrione. Background technique [0002] At present, 2,4-D butyl ester, dicamba, bromoxynil, and Yunongle are mainly used as post-emergence herbicides in corn fields in my country. Among the stem and leaf herbicides, 2,4-D butyl ester, dicamba, bromoxynil, etc. only have good control effects on broad-leaved weeds, but are ineffective against grass weeds; the stem and leaf treatment agent nicosulfuron is effective against Both broad-leaved weeds and gramineous weeds have good control effects, but because of their high cost and insufficient safety for certain varieties of corn, their large-scale application is affected. [0003] Mesotrione is a new type of triketone herbicide, which can be used for pre-emergence soil treatment and post-emergence spraying of stems and leaves. crop safety. At the same time, its biological...
