适用范围
杀螟丹能用于防治鳞翅目、鞘翅目、半翅目、双翅目等多种害虫和线虫，对捕食性螨类影响较小。

使用方法
1、水稻害虫的防治 二化螟、三化螟每亩用50%可溶性粉75-100g，对水40-50kg喷雾。 稻纵卷叶螟、稻苞虫每亩用50%可溶性粉100-150g，对水50-60kg喷雾。
2、蔬菜害虫的防治 小菜蛾、菜青虫每亩用50%可溶性粉25-50g，对水50-60kg喷雾。
3、茶树害虫的防治 用50%可溶性粉1000-2000倍液均匀喷雾。
4、甘蔗害虫的防治 每亩用50%可溶性粉剂100-125g，对水50kg喷雾，或对水300kg淋浇蔗苗。
5、果树害虫的防治 用50%可溶性粉剂1000倍液均匀喷雾。
6、旱粮作物害虫的防治 玉米螟每亩用50%可溶性粉剂100g，对水100kg喷雾或均匀灌在玉米心内。蝼蛄用50%可溶性粉拌麦麸(1：50)制成毒饵施用。

注意事项
1、水稻杨花期或作物被雨露淋湿时不宜施药，喷药浓度高对水稻也会有药害，十字花科蔬菜幼苗对该药敏感，使用时小心。
2、若中毒，应立即洗胃，从速就医。
