Problems solved by technology

However, due to the long-term use of sethoxydim 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 lim

Abstract

The invention belongs to the field of pesticides and discloses a herbicidal composition containing haloxyfop-R-methyl and sethoxydim and application of the herbicidal composition. The herbicide takes haloxyfop-R-methyl and sethoxydim as the main active ingredients, wherein the mass ratio of haloxyfop-R-methyl to sethoxydim is (1-65):(1-75) and haloxyfop-R-methyl and sethoxydim 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 advantages of wide herbicidal spectrum and long efficacy duration and does no harm to the corn and the aftercrops pn 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 high-efficiency haloxyfop-pyl and sethoxydim and an application thereof. technical background [0002] High-efficiency haloxyfop, also known as high-efficiency Gai Cao Neng, chemical name: methyl 2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxyl)phenoxy]propionate. It belongs to phenoxycarboxylic acid herbicides, is a fatty acid synthesis inhibitor, and is a new generation of fluorinated heterocyclic herbicides with high efficiency. The drug is a systemic conduction herbicide, which is absorbed by leaves, stems and roots, inhibits the biosynthesis of fatty acids in plants, stops cell growth and division, and destroys lipid-containing structures such as cell membranes, resulting in the death of weeds. The herbicide stems and leaves can be quickly absorbed by the leaves of gramineous grasses after treatment, and t...
