Abstract

A composite herbicide for rape field contains the pyrimidine benzylamine kind of herbicide, at least one of quizalofop-ethyl, fluazifop-p-butyl, haloxyfop, fenoxaprop and sethoxydim, acetochlor, alachlor, napropamide, ehaprochlor, metolachlor, ethamet sulfuron and benazolin. Its advantages are high effect, broad spectrum, low dosage and high safety.

Description

technical field [0001] The present invention relates to a kind of agricultural herbicide chemical composition, is precisely by pyrimidine benzylamine herbicides (propetifen and propetofen) and following at least one rapeseed herbicide: quizalofop-ethyl ( Acetyl-CoA carboxylase (ACCase) such as quizalofop-ethyl), fluazifop-p-butyl, haloxyfop, fenoxaprop, sethoxydim, etc. Inhibitors, acetochlor, alachlor, napropamide, ehaprochlor, metolachlor and other chlorinated amide herbicides, amines A binary or ternary herbicide composition compounded with ethametsulfuron and benazolin for controlling weeds in rapeseed fields and application thereof.
