摘要
Abstract
ZJ3265 ｛ ( E + Z) -2- [2- (4-cyanophenyl) -1 - [3- ( trifluoromethyl ) phenyl]ethylidene]-N- [4-(difluoromethoxy) phenyl]hydrazinecarboxamide ｝ is a novel insecticide in China.Toxicity of ZJ3265 against Mythimna separata, Plutella xylostella and Prodenia litura was tested in the laboratory by leafdipping method, and the field efficacy of ZJ3265 in controlling P.xylostella, P.litura, Spodoptera exigua and Pieris rapae was evaluated.The results showed that the LC50values of ZJ3265 against M.separata,P.xylostella and P.litura were 1.37(1.16 -1.62),18.53 (15.13 -22.10) and 15.40 ( 11.98 - 18.85 ) mg/L, respectively.The control efficacy of ZJ3265 ( 240 SC ) against P.xylostella,P.litura,S.exigua and P.rapae was 74.9％ ,76.7％ ,70.3％ and 84.4％ ,respectively,three days after the treatment of ZJ3265 at 120 g a.i./ha.No crop injury was observed at the dosage of the tests.关键词
