Herbicide composition containing methyl sulcotrione

Abstract

A composite herbicide contains sulcotrine-methyl and one of 18 herbicide including propisochlor, acetochlor, atrazine, etc.

Description

Technical field:

[0001] The invention relates to a binary compound herbicidal composition containing mesotrione, which is mainly used for weeding corn fields. Background technique:

[0002] At present, the herbicides used in cornfields in my country mainly include A-B mixture (atrazine + acetochlor) applied before seedlings, 2,4-D butyl ester, dicamba, bromoxynil, Yunongle, etc. applied after seedlings. . Because atrazine has a long residual effect in the soil, it is not conducive to crop rotation and stubble, which not only affects the subsequent planting of cruciferous vegetables, but also causes phytotoxicity to the subsequent planting of wheat and soybeans, and the herbicide used in soil treatment The herbicide effect is greatly affected by soil moisture, and the drug effect is poor or even ineffective during drought; while 2,4-D butyl ester, dicamba, bromoxynil, etc. are only effective against broad-leaved weeds in stem and leaf treatment herbicides. Good control effec...
