Field Control Experiments of 6 Pesticides to Citrus Psyllid

[Objective]The propose was to screen a good quick result,anti-efficient prevention and treatment of citrus Psylla Pharmacy. [Methods]The test were collected in the citrus orchards of citrus psylla adult vaccination stocking the host in the citrus Psylla Rutaceae Murraya paniculata on until the breeding to two-three-generation experiment after spraying. [Results]The Beta-cypermethrin+ Chlorpyrifos 515.00 mg/kg of six kinds of tested pesticids had quick result and long effect to Citrus Psylla after treating of 1,3,7,15 d,the control efficiency has reached 100%,control efficiency was still up to 94.5% after 30 d,it showed that this pesticides played a role in killing the eggs. Cypermethrin +Chlorpyrifos EC 477.00 mg/kg,Emamectin benzoate + Cypermethrin +Chlorpyrifos EC 479.00 mg/kg after 1,3,7,15 d,control efficiency was up to 100%,but after treating 20 d or 30 d,it was significantly lower than Beta-cypermethrin+ Chlorpyrifos 515.00 mg/kg. Beta-cyfluthrin had a high Controlling effect on citrus psylla,After treating of 1,3,7,15 d,the control efficiency of 16.67 mg/kg were all over 95%. Ethofenprox had good quick result to psyllid,but the holding is poor efficiency.Nitenpyram AS 100.00 mg/kg of citrus Psyllid effect of anti-poor,but also for temperature-sensitive. [Conclusion] Cypermethrin +Chlorpyrifos EC 477.00 mg/kg and Emamectin benzoate + Cypermethrin +Chlorpyrifos EC 479.00 mg/kg quick result was better,but the effect was lower than. Nitenpyram AS 100.00 mg/kg of citrus Psyllid effect of anti-poor,production should not be used to control citrus psyllid.Beta-cypermethrin+ Chlorpyrifos 515.00 mg/kg control effect of citrus Psylla significant,coud be very good to control citrus psylla.
