Abstract

The invention discloses a wheat filed weeding combination. The wheat filed weeding combination comprises the following effective components by weight percentage: 1-20 percent of pyribenzoxim, 1-20 percent of carfentrazone-ethyl, 1-50 percent of fluroxypyr, and pesticide adjuvant in balancing amount. Pyribenzoxim, carfentrazone-ethyl and fluroxypyr have remarkable synergism after being compounded, and are used less in the compounded agent than to be used individually, so that the agent use cost is lowered, and the weeding combination is suitable for preventing and weeding weed in wheat fields.

Description

technical field [0001] The pesticide herbicide composition of the present invention uses saflufenacil, mefentrazone and fluroxyfen as active ingredients, and is used for controlling annual weeds in wheat fields and the like. 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] Saflufenacil is an oxime ester compound, a broad-spectrum selective post-emergence herbicide. The mechanism of action is similar to that of sulfonylurea and imidazolone herbicides, both of which are a...
