The Development and Damage of Ficus Thrips on Potted ficus and its Formula Pesticide Screening for Prevention and Control
Thrips' species,damage process and occurrence regularity were researched and identified in the potted ficus demonstration base in Zhangzhou as a observation point.The best formula pesticide and its concentration in the field for prevention and control of ficus trips were screened and determined in the use of Avermectins+ acetamiprid,MTMC+acetamiprid,Chlorpyrifos + acetamiprid these three teams of formula pesticides.The result showed that Gynairothrips uzeli Zimmerman is the main pest on potted Ficus.The control effect of MTMC + acetamiprid in the mixing ratio of four to one is most ideal because the control effects of it all exceeded 93.48% in 3 to 10 days after pesticide application,meanwhile,it had no phytotoxicity and best performance-price ratio.So MTMC+acetamiprid is the best formula pesticide and its recommendation dilution multiple was 500 to 1 500 times in the field.
