STUDYON CONTROL EFFECT OF CHLORANTRANILIPROLE AND 6%EMAMECTIN BENZOATE AND HEXAFLUMURON ON GRASSLAND CATERPILLAR
Two biological insecticides of chlorantraniliprole,6%emamectin benzoate and hexaflumuron were used in the experiment to control Qinghai grassland caterpillars at three different doses.The results show that the average control effect of two insecticides at three doses was over 90%after 5 days of application,which achieved the control requirements of grassland caterpillar in Qinghai province.Considering the cost of the medicine,it was suggested to use 6%emamectin benzoate and hexaflumuron as the emergency reserve medicine of grassland caterpillar in Qinghai province and optimal dosage was 150 ml/hm2.
