Control Effects of 9 Pesticides on Tomato Leafminer, Tuta absoluta (meyrick)

【Objective】 In Xinjiang in the hope of providing techniques to prevent it from further spreading. 【Methods】 2 doses of 9 kinds of insecticides were selected, and 18 field treatments and 1 water control were applied in the field. The insect population survey was conducted at 1 d, 3 d, 7 d, and 14 d after the treatment to calculate the insect population reduction rate and control effect to screen green and efficient pesticides. 【Results】 The field efficacy test results showed that: using 60 mL / 667m² of Avi chlorobenzoyl SC, 42 mL / 667m² of 24% methacylhydrazine SC, and 7.5 mL / 667m² of 20% chlorantraniliprole SC, the control effect for the tomato leaf miner disease was more than 90%, and the latter two had the most obvious effect in the later stage, which was also persistent. 0.35% Azadirachtin EW at 37.5 mL / 667m² had the lowest prevention effect in the whole process. 【Conclusion】 60 mL / 667m² of Avi chlorobenzoyl SC, 42 mL / 667m² of 24% methicylhydrazine SC, and 7.5 mL / 667m² of 20% chlorantraniliprole SC should be used alternately among the pharmacy.
