种子处理剂防治机插稻恶苗病试验效果

摘要

In order to screen seed treatments for controlling bakanae disease in rice field by mechanically transplanting seed-ings, the contrast trials were carried out by soaking the seeds in JS399-19 25%SC and prochloraz+cartap 16%WP, et al. The results showed that JS399-19 25% SC had good control effect, and could replace prochloraz to control rice bakanae disease. The control effiects of prochloraz+cartap 16%WP mixed with deodorization ethylicin 80%EC and ethylicin 25%EC could be improved.%为了筛选防治机插稻恶苗病的浸种药剂，采用25%氰烯菌酯SC、16%咪鲜·杀螟丹WP等药剂浸种并进行田间药效对比试验。结果表明：25%氰烯菌酯 SC 对水稻恶苗病具有优异的防治效果，可作为咪鲜胺类浸种药剂的替代品种；16%咪鲜·杀螟丹WP与80%乙蒜素EC或25%脱臭乙蒜素EC混用可提高对恶苗病的防治效果。展开▼
