几种杀螨剂对柑橘红蜘蛛的防治效果

Control Effect of Several Acaric Agents on Citrus Red Spider

本研究使用了40%氟啶胺悬浮剂等5种药剂防治柑橘红蜘蛛的药效试验,结果表明,施药1 d和15 d后,40%氟啶胺悬浮剂、110g/L乙螨唑悬浮剂、43%联苯肼酯悬浮剂对柑橘红蜘蛛的防效均在80%以上,速效性和持效性均好;而15%联苯菊酯悬浮剂、15%哒螨灵乳油施药1 d后防效分别为81.71%和83.15%,药后15 d分别为47.02%和68.12%,速效性好但持效性差。建议在实践中使用40%氟啶胺悬浮剂、110 g/L乙螨唑悬浮剂、43%联苯肼酯悬浮剂防治柑橘红蜘蛛。

In this paper, the efficacy of several acaric agents such as fluazinam were carried out in the field. The results showed that the control of 40 % fluazinam SC 110 g/L etoxazole SC and 43% bifenazate SC on citrus red spider was more than 80 % after 1 d and 15 d. After 1 d and 15 d, the control effect of 15 % biphenyl pyrethroid SC were 81.71 % and 47.02 %, respectively. After 1 d and 15 d, the control effect of 15 % pyridaben EC were 83.15 % and 68.12 %, respectively. We suggested fluazinam etoxazole and bifenazate should be used to control citrus red spider.
