Efficient cotton field herbicide

Abstract

The invention discloses an efficient cotton field herbicide. The efficient cotton field herbicide is prepared from the following raw materials in parts by weight: 10-20 parts of fatty alcohol-polyoxyethylene ether, 5-8 parts of fluroxypyr, 2-5 parts of trifloxysulfuron, 15-25 parts of pyrithiobac-sodium and 20-30 parts of vegetable oil. The efficient cotton field herbicide has a good weeding effect, causes small harm on crops, and is convenient to produce, low in use cost and low in weed drug resistance.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a high-efficiency herbicide for cotton fields. 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 pests and weeds. At present, the commonly used herbicides in cotton fields are: trifluralin, acetochlor and so on. Trifluralin is a long-residual herbicide, which is easy to cause subsequent phytotoxicity, and needs to be mixed with soil when used, which is time-consuming and labor-intensive, and will also cause cotton root swelling after use; And higher soil moisture requirements. At the same time, due to the continuous use of herbicides in cotton fields for many years, the problem of phytotoxicity has become increasingly apparent. SUMMARY OF THE INVENTION...

Problems solved by technology

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 require higher soil moisture
