Abstract

The present invention relates to a binary compound synergistic herbicide containing mesotrione A and a herbicide B, and is used for settling the insufficiencies of single function, inferior effect, large residual quantity, etc. of herbicide in the chemical prevention of weed of the corn field, wherein, A is mesotrione, and B is one chemical selected from B1 of 2,4-D, B2 of 2,4-D sodium, B3 of 2,4-D ethyl, B4 of 2,4-D butyl, B5 of 2,4-D isoctyl, B6 of 2,4-D dimethylamine, B7 of 2-methyl-4-chloro-phenoxyacetic acid MCPA, B8 of MCPA sodium, B9 of MCPA ethyl, B10 of MCPA butyl, B11 of MCPA isoctyl, and B12 of MCPA dimethylamine. The binary combination synergistic herbicide used for preventing weed of the corn field according to the invention contains 1-99 weight parts of mesotrione A and herbicide B and conventional herbicide adjuvant and / or carrier. The binary combination synergistic herbicide according to the invention has the effects of high weed killing effect, broad weed killing spectrum, high safety to the corn, no side effect, no influence to the flowing crop and low use cost.

Description

Technical field: [0001] The present invention relates to a compound synergistic herbicide composition, more specifically a binary compound synergistic herbicide containing nitrosulcotrione A and herbicide B, wherein A is nitrosulcotrione, herbicide B is 2,4-D acid B1, 2,4-D sodium salt B2, 2,4-D ethyl ester B3, 2,4-D butyl ester B4, 2,4-D isooctyl ester B5, 2,4 -D dimethylamine salt B6, dimethyltetrachloric acid B7, dimethyltetrachlorosodium salt B8, dimethyltetrachloroethyl ester B9, dimethyltetrachlorobutyl ester B10, dimethyltetrachloroisooctyl ester B11, dimethyltetrachloroethyl One of tetrachlorodimethylamine salts B12. Background technique: [0002] At present, the sown area of ​​my country's corn field is nearly 400 million mu, which is one of the three major food crops, with an output of about 130 million tons. There are many kinds of herbicides currently used in corn fields, such as acetochlor, atrazine, nicosulfuron, 2,4-D butyl ester, etc. Acetochlor herbicides...
