Low-tolerance cotton field weedicide

Abstract

The invention discloses low-tolerance cotton field weedicide. The low-tolerance cotton field weedicide is prepared from the following raw materials in parts by weight: 6 to 12 parts of high-efficiencyhaloxyfop-methyl, 5 to 10 parts of fatty alcohol-polyoxyethylene ether, 10 to 15 parts of isopropyl aniline, 8 to 18 parts of quizalofop-P-tefuryl and 20 to 30 parts of vegetable oil. The low-tolerance cotton field weedicide is good in weeding effect, small in damage to crops, convenient to produce, low in use cost and low in weedicide resistance of weeds.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a herbicide for cotton fields with low tolerance. Background technique [0002] Cotton is an important economic crop in my country. Cotton is widely distributed in my country and is planted from south to north. The total sown area of ​​cotton in my country is about 75 million mu. The main factors affecting cotton yield are insect damage and weed damage. At present, herbicides commonly used in cotton fields are: trifluralin, acetochlor, etc. Trifluralin is a herbicide with long residual effect, which is easy to cause phytotoxicity after cropping, and it must be mixed with soil when used, which is time-consuming and labor-intensive, and it will also cause swelling of cotton roots after use; acetochlor has a narrow herbicidal spectrum and short duration And it requires higher soil moisture. At the same time, due to the continuous use of herbicides in cotton fields for many years, the ...
