Abstract

A composite herbicide contains (RS)-2-chloro-3-[2-chloro-5-(4-difluoromethyl-4,5- dihydro-3-methyl-5-oxy-1,2,4-triazole-1-yl)-4- fluorophenyl] propionic acid, tribenuron-methyl, and fenoxaprop-P-ethyl in weight ratio of (0.1-49):(0.1-49):(1-49). Its advantages are high effect and high safety.

Description

technical field [0001] The present invention relates to a herbicide composition. technical background [0002] There are many kinds of weeds in the wheat field, the density is high, and the damage is serious all the year round. It is one of the main obstacles restricting the high and stable yield of wheat. In the past, the traditional control methods were intertillage weeding and manual removal, but it was laborious and time-consuming and incomplete. cause harm. In recent years, the promotion and application of chemical weeding in production has developed rapidly. Flufentrazone is a selective herbicide for stem and leaf treatment. It has a good killing effect on broad-leaved weeds in wheat fields, such as Artemisia sativa and shepherd's purse. If it is made into a composition with some complementary herbicides , their herbicidal spectrum and comprehensive herbicidal effect can have a surprising increase. In the seventh issue of "Pesticide" magazine in 2001, the Xiaoxian C...
