Abstract:In order to screen the safe and efficient insecticides, 2.5% Diphenthrin EC, 0.3% Matrine AS, 0.5% Azadirachtin EC, 1.6% Wolfish toxin EC, and 1.5% Pyrethrin EW were selected for field efficacy test. The results showed that 7 days after application, control effects of 2.5% Diphenythrin EC at 5 000 times, 1.6% Wolfish toxinEC, 0.3% Matrine AS at 600 times, 0.5% Azadirachtin EC at 500 times, 1.5% Pyrethrin EW at 600 times were 86.42%, 78.85%, 70.06%, 62.78% and 59.53%, respectively. The control effect of 2.5% Diphenthrin EC at 5 000 times and 1.6% Wolfish toxin EC at 600 times was significantly higher than other pesticides. From the perspective of ecology, safety and efficiency, 1.6% Wolfish toxin EC at 600 times was recommended for field control.
