Abstract

The invention discloses a herbicide composition, containing A, B, two active ingredient, and right amount agriculturally acceptable surfactant and solid or liquid diluent. Active ingredient A is selected from 3-methyl-2-[5-(2-chlor-4- trifluoromethylphenoxy)-2-nitrylbenzoxy]-3-ethyl crotonate, active ingredient B is selected from any of the following herbicide: sethoxydim, Clethodim, quizalofop-P-ethyl, Haloxyfop-R, fluazifop-P-butyl, fenoxaprop-ethyl, cyhalofop-hutyl, quizalofop-P-tefuryl. Weight portions ratio of A and B is 1:80 to 80:1. Herbicidal compositions can be processed to missible oil, suspending agent (emulsion), aqueous emulsion, microemulsion, water dispersed granule, wettable powder, it can effectively prevent and kill multiple weeds of soybean field.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, and in particular relates to the preparation and application of a new herbicidal composition for controlling gramineous weeds and broadleaf weeds in soybean fields. Background technique [0002] 3-methyl-2-[5-(2-chloro4-trifluoromethylphenoxy)-2-nitrobenzoyl]-3-butenoic acid ethyl ester is a product developed by China Shenyang Research Institute of Chemical Industry A broad-spectrum, pre- and post-emergence herbicide that can effectively control a variety of weeds in soybean, wheat, and corn fields. The herbicide has the characteristics of fast action speed and herbicidal activity for treating soil and stems and leaves. The preparation and application of the compound have been disclosed in the Chinese invention patent application CN1325624A. Further field trials show that the herbicide is relatively safe to soybeans and other leguminous crops at a dose of 300-600g a.i. / ha. Under the dose of ...
