Ethoxyfen-ethyl and pyroxsulam-containing herbicide composition

Abstract

The invention relates to the technical field of pesticides and discloses an ethoxyfen-ethyl and pyroxsulam-containing herbicide composition which comprises two active ingredients including ethoxyfen-ethyl and pyroxsulam, the weight ratio of the ethoxyfen-ethyl to pyroxsulam is 3:50-75:2, the mass percentage content of the ethoxyfen-ethyl and pyroxsulam is 0.5-80% of compounded herbicide. After the ethoxyfen-ethyl and pyroxsulam active ingredients are compounded, the deficiencies of separately using the ethoxyfen-ethyl and pyroxsulam can be made up for, not only can the annual grasses in wheat field be prevented and removed, but also broad-leaf weeds can be prevented and removed, and the ethoxyfen-ethyl and pyroxsulam-containing herbicide composition has obvious synergism. The herbicide composition not only has an obvious weed control effect, but also is good in wheat security, has no influence on the afterreap crop, thus being a desirable herbicide.

Description

【Technical field】 [0001] The present invention relates to a herbicide composition for preventing and controlling weeds in wheat fields, in particular to a herbicide for preventing and treating grassy weeds and broad-leaved weeds in wheat fields, which is based on chlorofluorfen and pyridinesulfone A dual herbicide composition with oxalan as an active ingredient. 【Background technique】 [0002] Wheat is the second largest grain crop in my country, accounting for 20% to 27% of the total area of ​​grain crops in the country, and its planting range covers almost all agricultural areas. In 2011, my country's wheat planting area was about 24 million hectares, with a total output of about 100 million tons. The area of ​​wheat grass damage accounts for 30% of the planting area in my country, of which serious grass damage accounts for about 10%. Chemical control of weeds in wheat fields is an important measure to ensure wheat production. Since the introduction of 2,4-D in 1956, the...

Problems solved by technology

The drug is absorbed by weed leaves, sheaths, stems or roots, accumulates at the growth point, inhibits acetolactate synthase, and cannot synthesize branched-chain amino acids, which in turn affects protein synthesis and cell division, causing weeds to stop growing, yellow, then die

It is used for the control of gramineous weeds such as hard grass, kanko, Japanese kanko, brome, wild oats, clubhead grass, multiflora ryegrass, etc. It is not ideal for broad-leaved weeds

In addition, when acesulfame is used as a single dose in the wheat field, the dosage is relatively high under the premise of ensuring the efficacy, and there is a hidden danger of phytotoxicity.
