几种化学农药及与微生物菌剂混配对温室草莓红蜘蛛的药效试验

Efficacy Test of Several Pesticides and Mixed with a Microbial Agent againstRed-spider on Strawberry in Greenhouse

为筛选出对温室草莓红蜘蛛具有较好防治效果的杀螨剂,对3种常用药剂及其与1种具杀螨作用的微生物菌剂混配进行药效比较试验。试验结果表明,阿维菌素和联苯肼酯的综合防效表现较好;菌剂与杀螨剂混配以螺螨酯的综合防效表现较佳,显著提高螺螨酯的防效。建议生产中草莓红蜘蛛防治优先使用阿维菌素、联苯肼酯,其次为菌剂与螺螨酯混配。

In order to screen out the acaricides with good control effect on strawberry red-spider in greenhouse,the efficacy comparison test was carried out on three commonly used pesticides and their mixture with one microbial agent.The results showed that avermectin and bifenazate had better comprehensive control effect.The combination of spirodifen and the microbial agent showed a better comprehensive control effect,and significantly improved the control effect of spirodifen.It was suggested that avermectin and bifenazate could be used preferentially in the control of strawberry red-spider in production,followed by the mixture of the microbial agent and spirodifen.
