Problems solved by technology

However, due to the long-term use of quizalofop-ethyl in soybean fields, some weeds have developed severe resistance to it
[0004] 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

Abstract

The invention belongs to the field of pesticides and discloses a herbicidal composition containing haloxyfop-R-methyl and quizalofop-p-ethyl and application thereof. The herbicide takes haloxyfop-R-methyl and quizalofop-p-ethyl as the main active ingredients, wherein the mass ratio of haloxyfop-R-methyl to quizalofop-p-ethyl is (1-80):(1-80) and haloxyfop-R-methyl and quizalofop-p-ethyl account for 1-85% of the herbicidal composition by mass. The herbicidal composition has obvious effect on controlling the postemergence weeds in the soybean fields, especially on controlling various grass weeds in the soybean fields. Compared with the single agent, the herbicidal composition reduces the drug dose, delays weed resistance, has the advantages of wide herbicidal spectrum and long efficacy duration and does no harm to the soybeans 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 fenflufenafen and quizalofop-p-ethyl and application thereof. Background technique [0002] High-efficiency flufenoxoling, also known as high-efficiency cover grass energy, chemical name: 2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxy)phenoxy] methyl propionate. It is a phenoxycarboxylic acid herbicide, a fatty acid synthesis inhibitor, and a new generation of fluorinated heterocyclic herbicides. The agent is a systemic and conductive herbicide, absorbed by leaves, stems and roots, inhibiting the biosynthesis of fatty acids in plants, stopping cell growth and division, and destroying lipid-containing structures such as cell membranes, resulting in the death of weeds. After the stem and leaves of the herbicide are treated, it can be quickly absorbed by the leaves of the grasses of the family Poaceae, conduct t...
