通过在水稻嘉早３５上施用２０％三唑磷乳油、１８％杀虫双水剂、１８％杀虫双撒滴剂和５％锐劲特胶悬剂４种药剂，比较其对二化螟的防治效果。室内模拟试验结果，４种药剂在不同剂量下对家蚕的毒性，不同药剂之间差异明显，高低次序为：锐劲特＞三唑磷＞杀虫双水剂＞杀虫双撒滴剂，锐劲特对家蚕的毒性最低；三唑磷在低浓度（１００ｍｇ／Ｌ）下对家蚕毒性较低，而在高浓度（５００，１０００ｍｌ／Ｌ）下对家蚕毒害很高；杀虫双水剂与撒滴剂对家蚕的毒性均较高。喷叶处理引起的家蚕死亡率最高，其次为喷虫处理，点滴处理对家蚕的毒害最小。锐劲特是一种适合在家蚕区推广应用的高效低蚕毒的杀螟药剂。结果表明，随着农药剂量的增加，呈现对二化螟的防效增高，同时对家蚕毒性亦增高的趋势。
Through the application of 20% triazophos EC, 18% insecticidal double-watering agent, 18% insecticidal double-drop dropping agent and 5% The prevention and treatment effect. Indoor simulation test results, four kinds of agents in different doses of silkworm toxicity, the difference between different agents was obvious, the order of high and low: fipronil> triazophos> insecticide Shuangshui agent> insecticide double-drop agent, sharp Triazophos had lower toxicity to silkworm at low concentration (100mg / L), but higher toxicity to silkworm at high concentration (500,1000ml / L) Drops on silkworm toxicity are higher. The highest mortality rate of silkworms caused by sprayed leaves was given, followed by the spray insecticide treatment, and the trickle-down treatment was the least toxic to silkworm. Regent is a suitable silkworm area to promote the use of high efficiency and low anti-worm agents. The results showed that with the increase of pesticide dosage, the control effect on Chilo suppressalis increased and the toxicity to the silkworm also increased.
