摘要
针对生产中防治水稻纹枯病可供选择农药品种相对单一的现状,于2006年进行了防治药剂的筛选试验。结果表明,爱苗和世高的防效好于生产上常用防治药剂井冈霉素。在第2次施药后8 d和15 d,爱苗30%EC 300 mL/hm2和世高10%水分散粒剂750 g/hm2的防治效果均分别与20%井冈霉素水溶性粉剂900 g/hm2差异显著。
The results from the selection experiment of fungicides with controlling rice sheath blight showed that the control efficiency of Armure and Score was better than Jingangmycin（the common pesticide to control sheath blight of rice in rice production）. The control efficiency of 300 mL/ha of 30% Armure EC and 750 g/ha of 10% Score WG on 8 d and 15 d after the second spraying was significantly higher than that of spraying 900 g/ha of 20% Jingangmycin AF.
