Abstract

The invention discloses a herbicidal composition containing flunmezone-sulam and fenflumezamide, the ratio of parts by weight of flunmezone-sulam and oxenmezamide in the composition is 10:1-1: 10. The percentage by weight of the sum of the weights of flucarbazone-sulam and mefenoxam in the composition is 1-80%; the effect of the herbicidal composition of the present invention on controlling annual weeds in paddy fields has been significantly improved compared with that of a single agent , reduces the dosage of pesticides, reduces the adverse effects of pesticides on the ecological environment, is of great significance to the comprehensive management of weed resistance, and has huge economic and social benefits.

Description

technical field [0001] The invention relates to a paddy field herbicidal composition, which is used for preventing and controlling annual weeds in paddy fields, which uses flucarbone sulfentrazone and fenpyramid as active ingredients. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Flucarbazone is an amide compound, a broad-spectrum selective post-emergence herbicide, and its mechanism of action is similar to that of sulfonylurea and imidazolone herbicides, both of whic...
