Herbicidal composition containing fluazifop-p-butyl and clethodim and application thereof

Abstract

The invention discloses a herbicidal composition containing fluazifop-p-butyl and clethodim and application thereof. The herbicidal composition takes fluazifop-p-butyl and clethodim as the main active ingredients, wherein the mass ratio of fluazifop-p-butyl to clethodim is (1-70):(1-80) and fluazifop-p-butyl and clethodim account for 5-85% of the herbicidal composition by mass. The herbicidal composition has obvious effect on preparing the herbicides for controlling the postemergence weeds in the soybean fields, especially the herbicides for controlling various grass weeds in the soybean fields. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the rapes and the aftercrops on the premise of improving the drug effect.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a herbicidal composition, in particular to a herbicidal composition containing refined fluazifop-fop and clethodim clethodim and an application thereof. technical background [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. Its structural formula is as follows: [0003] [0004] 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, creeping wheatgrass, etc. It can be applied in the whole f...

AI Technical Summary

Problems solved by technology

However, it is ineffective against broad-leaved weeds, and due to the long-term use of clethodim in soybean fields, some weeds have developed severe resistance to it

[0008] At present, herbicides in soybean fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in soybean fields. Too long, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
