AI Technical Summary

Problems solved by technology

However, it is ineffective against broad-leaved weeds, and some weeds have developed serious resistance to it due to the long-term use of furfurofate in soybean fields
[0009] At present, herbicides in soybean fields are limited by crop safety and herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in soybean fields In addition, some herbicides are likely to cause residual toxicity to current crops or subsequent crops due to their high water solubility or long field duration, excessive dosage or uneven application.

Abstract

The invention discloses a weeding composition containing fluazifop-p-butyl and quizalofop-p-tefuryl and application thereof. The fluazifop-p-butyl and the quizalofop-p-tefuryl are used as main effective ingredients of the weeding composition, and the mass ratio of the fluazifop-p-butyl to the quizalofop-p-tefuryl is 1-80: 1-80. The weeding composition delays weed resistance on the premise of improving the pesticide effect compared with single agent, has wide weeding spectrum and long acting period, has safety for soybean and subsequent crops, and can be used for preparing herbicide for controlling weeds among soybean field seedlings.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and relates to a binary compound composition of fluazifop-methyl and quizalofofuryl. The herbicidal composition can be applied to post-emergence weeding in soybean fields. Background technique [0002] Fluazifop-methyl, also known as Jingwenshade, chemical name: (R)-2-{4-[(5-trifluoromethyl)-2-yl-pyridyl]oxy}propionic acid butyl ester . It belongs to phenoxycarboxylic acid herbicides, is a fatty acid synthesis inhibitor, and is a new generation of fluorinated heterocyclic herbicides with high efficiency. [0003] Its structural formula is as follows: [0004] [0005] Mainly used for the control of barnyardgrass, wild oats, foxtail, golden foxtail, goosegrass, mermaid, stephenia, teff, brome, barley, rye, millet, bluegrass, bermudagrass, double spikes Annual and perennial gramineous weeds such as paspalum, false sorghum, reed, wild silkworm, imperata,...
