水稻立枯病及恶苗病是水稻苗期的主要病害,3%恶・甲・咪鲜胺悬浮种衣剂种子包衣可同时防治这两种病害。为验证其对水稻的安全性及对水稻立枯病和恶苗病的防治效果,以水稻品种东农428为试材进行了田间药效试验。结果表明：其对水稻出苗、秧苗生长及成熟期均无不良影响,对水稻安全,并且增产显著；对水稻立枯病的平均防效大于65%,对恶苗病的平均防效大于85%；在水稻浸种前,3%恶・甲・咪鲜胺悬浮种衣剂按药种比1∶(40~60)的比例进行种子包衣为适宜施药时期和用药量。%Rice seedling blight and bakanae disease are major diseases of the rice seedling ,3% Hymexazol・Metalaxyl・Prochloraz FSC could simultaneously against to the two diseases .In order to vertify its security on rice and control effect on rice seedling blight and bakanae disease ,the field efficacy trials were carried out with rice variety Dongnong 428 .The results showed that :It had no adverse effect on rice seedling emergence ,seed-ling growth and maturity ,it safety for rice and could increase rice yield remarkablely .The average control effi-ciency to rice seedling blight was more than 65% ,the average control efficiency to rice bakanae disease was more than 85% ;Before seed soaking ,3% Hymexazol・Metalaxyl・Prochloraz FSC and seeds mixed with propor-tion of 1∶(40 ~ 60)were appropriate application period and dosage .
