摘要
通过 1998～ 1999年在浙江省杭州、诸暨、余姚、萧山等地的多次田间小区和大区示范及模拟试验 ,证实农美利防治水稻直播田杂草的效果 ,明确其对水稻安全性和药害表现 ,并提出其应用技术。
Application techniques of bispyribac sodium for controlling weeds were studied in direct seeded rice fields in Zhejiang,China in 1998-1999.Results showed bispyribac sodium is very effective on gramineae,sedge and broad leaf weeds including Echinochloa crusgalli,Paspalum distichum, and Alternanthera philoxeroides, but not on Leptochloa chinensis. It was recommended that 10% bispyribac sodium SC be sprayed at 225-450 ml/hm 2 with 450 L/hm 2 of water during 3 to 5 leaf stage of barnyardgrass,and sometimes applied with thiobencarb or fenoxaprop p ethyl specially for L.chinensis.
