Abstract

The invention relates to a weeding combination containing pyraflufen-ethyl and a diphenyl ether compound, which is mainly characterized in that the weeding combination contains 1-60 percent of active ingredient A, i.e. the pyraflufen-ethyl, 1-80 percent of active ingredient B, adjuvant and other excipients, the active ingredient B is selected from acifluorfen, fomesafen or fluoroglycofen-ethyl, and the weeding combination is prepared into wettable powder, water dispersible granules, oil suspending agent, suspending emulsion, microemulsion and emulsion in water. The weeding combination provided by the invention can be used for preventing and controlling weeds in soy bean fields and paddy fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing effective components A metazachlor and active components B, which is used for preventing and controlling weeds in soybean and paddy fields. 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 pesticides wi...
