摘 要：
[目的]明确31%苯·吡·甲草胺泡腾颗粒剂防除早晚两造水稻移栽田一年生杂草的防除效果、使用剂量、使用适期及其安全性。[方法]采用田间小区试验方法。[结果]该药剂在水稻移栽返青期,推荐剂量186.0~372.0 g a.i./hm2,能够有效防除一年生禾本科杂草、阔叶杂草和莎草科杂草,重点防除稗草、丁香蓼、水花生、碎米莎草和水虱草等杂草。[结论]在推荐使用剂量内对水稻安全,但高剂量会产生一定的药害,是一种方便高效经济安全的水稻移栽田除草剂。

摘 要：
[Aims] The aim of this study is to determine the control effi cacy of mefenacet+pyrazosulfuron-ethyl+alachlor 31% EA on annual weeds, optimal dosage, suitable period and to investigate the rice safety in transplanted rice fi eld. [Methods] Field trial method was used. [Results] The results showed that the mefenacet+pyrazosulfuron-ethyl+alachlor 31% EA can control effectively on annual grasses weeds [Echinochloa crusgalli(L.) Beauv.] and annual broadleaf weeds [Ludwigia prostrata and Alternanthera philoxeroides(Mart.) Griseb.] and sedge weeds(Cyperusiria L. and Fimbristylis miliacea L. Vahl) with recommended dosage of 186.0-232.5 g a.i./ha before the rice transplanting turns green. [Conclusions] Mefenacet+pyrazosulfuron-ethyl+alachlor 31% EA is safety on rice at the recommended dose, but higher application concentration led to phytotoxicity. The mefenacet+pyrazosulfuron-ethyl+alachlor 31% EA is a convenient, economic, effi cacious and safe herbicide in the transplanted rice fi eld.
