Toxicity and field efficacy of novel compound ZJ3757 against lepidopterous pests on vegetables

Toxicity of novel compound ZJ3757 against Plutella xylostella,Prodenia litura and Spodoptera exigua were tested by leaf dip bioassay.The LC50 values were 0.088,0.905 and 0.095 mg/L, respectively,which were almost equivalent to that of chlorantraniliprole and flubendiamide.Field trials showed that the control efficacy of 20% ZJ3757 SC against P.xylostella,S.exigua,P.litura and Pieris rapae were 88.41%, 92.72％,82.07% and 98.39％,respectively,after seven days treatment at the dosage of 15 g a.i./hm2, which were equivalent to that of chlorantraniliprole,higher or equivalent to that of flubendiamide,indoxacarb and emamectin benzoate.The results suggested ZJ3757 is a new insecticide effective against P.xylostella,P.litura,S.exigua and P.rapae on vegetables.
