新型杀虫剂富锐和美满对甜菜夜蛾的防治效果

Control Effect of Two New Type of Insecticides of Zeta-cypermethrin and Methoxyfenozide to Spodoptera exigua

室内和田间药效试验结果表明,新型药剂18.1％富锐乳油、24％美满悬浮剂对甜菜夜蛾具有良好的防治效果,富锐5 000倍液与辛硫磷1 500倍液、美满6 000倍液与高效氯氟菊酯2 000倍液混合使用,可降低防治成本。

Laboratory experiments and field trials were conducted to determine the efficiency of two new type of insec-ticides to Spodoptera exigua. The results showed that both insecticides of 18.1% Fury EC and 24% Runner SC had excel-lent control efficacy to the insect pest. Tank-mixing of the 5 000-fold dilution of Funy with 1 500-fold phoxim or 6 000-fold Runner with 2 000-fold Beta-cypermethrin can decrease the control cost .
