Abstract

The invention relates to a weeding composition containing carfentrazone-ethyl and metamifop. The composition is mainly characterized by comprising 1-60 percent of carfentrazone-ethyl and 1-60 percent of metamifop serving as active ingredients, an aid and other excipients and being prepared into wettable powder, water-dispersible granules, a suspending agent, a micro-emulsion, an aqueous emulsion and the like. The weeding composition is used for preventing and controlling paddy field cockspur grass and other gramineae weeds and for controlling a part of broadleaf weeds and certain sedges.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition of bispyribac and fenpyramid, which is used for preventing and treating common weeds. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can be obtained from the pesticides with complementary...
