Description

technical field [0001] The invention relates to the field of agriculture, in particular to a cotton field herbicide. 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 needs to be mixed with soil when used, which is time-consuming and labor-intensive, and it will also cause swelling of cotton roots after use; And it requires higher soil moisture. 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. Contents of the invent...
