A comprehensive herbicide for paddy fields

Abstract

The present invention provides a comprehensive herbicide for paddy fields, which includes component A and component B, wherein component A is mesotrione, and one or more of component A and component B Item compound, used for weeding in the field; component B is alachlor, metolachlor, propachlor, acetochlor, pretilachlor, butachlor, mefenacet, quinclorac , Cyhalofop-methyl, pendimethalin, saponin, bispyribac, saflufenacil, cyclopyrafen, pyrifluben. After the above scheme is adopted in the present invention, the composition of component A and component B has a synergistic effect, and has a good control effect on both grass weeds in paddy fields and broad-leaved and sedge weeds , and the residual effect period is short, does not affect the growth of the next crop, and is friendly to the environment.

Description

[0001] technical field [0002] The invention relates to the technical field of weeding in paddy fields, in particular to an all-round herbicide for paddy fields. Background technique [0003] In paddy fields, gramineous weeds, broad-leaved weeds and sedge weeds are usually harmful at the same time. In the early 1990s, with the promotion of sulfonyl lipid herbicides, amide herbicides and their compound preparations application, the harm of the above three types of weeds in paddy fields has been well controlled, but due to the long-term use of sulfonylurea herbicides, the resistance of weeds to them has also increased year by year, and broad-leaved weeds and Cyperaceae weeds have The damage to rice is increasing. At present, it is necessary to develop an all-round weed control that can kill broad-leaved or sedge weeds that are resistant to sulfonylurea herbicides as well as control gramineous weeds as soon as possible. agent. Contents of the invention [0004] The object ...
