Abstract

一种含有吡草胺和喹禾灵的除草组合物,其中制备方法及用途,它是由化合物(A)吡草胺与化合物(B)喹禾灵组成的混合物。其特征是化合物(A)吡草胺与化合物(B)喹禾灵的比例为1-100∶1。本发明的组合物可以加工成可湿性粉剂、乳油、悬浮剂、水分散粒剂。本发明所提供的除草组合物能有效防除油菜田中的看麦娘、凤草、野燕麦、马唐、稗、早熟禾、狗尾草等一年生禾本科杂草和苋、春黄菊、母菊、蓼、芥、茄、繁缕、荨麻和婆婆纳等阔叶杂草。防效显著高于单用化合物(A)或化合物(B)的防效,并且大幅度减少了多种活性物质的施用剂量。
The invention provides to a herbicidal composition containing metazachlor and quizalofop-ethyl and a preparation method and application. The composition is the mixture of the compound (A) metazachlor and the compound (B) quizalofop-ethyl. The composition is characterized in that the ratio of the compound (A) metazachlor to the compound (B) quizalofop-ethyl is 1-100:1; and the composition can be processed into wettable powder, emulsifiable concentrates, suspending agents and water-dispersible granules. The herbicidal provided by the invention can effectively prevent and kill off the annual grass weeds such as amur foxtail, feng grass, wild oats, crabgrass, millets, bluegrass, bristlegrass and the like and the broadleaf weeds such as amaranth, chamomile, matricary, knotweeds, mustard, eggplants, chickweeds, smartweeds, speedwell and the like in the rape fields.
