Yang, Ji-Chun published the artcileDesign, synthesis and insecticidal evaluation of aryloxy dihaloropropene derivatives, Name: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is insecticide aryloxy dihaloropropene derivative; Aryloxy dihalopropene derivatives; Insecticidal activities; Intermediate Derivatization Methods (IDM); Structure–activity relationship.
Plutella xylostella (P. xylostella) is a highly migratory, cosmopolitan species and one of the most important pest of cruciferous crops worldwide. Pyridalyl as a novel class of insecticides has good efficacy against P. xylostella. On the basis of the com. insecticide pyridalyl, a series of new aryloxy dihaloropropene derivatives were designed and synthesized by using Intermediate Derivatization Methods. Their chem. structures were confirmed by 1H NMR, high-resolution mass spectrum (HRMS), and single-crystal X-ray diffraction anal. The insecticidal activities of the new compounds against P. xylostella were evaluated. The results of bioassays indicated that most of the compounds showed moderate to high activities at the tested concentration, especially compounds (I) and (II) displayed more than 75% insecticidal activity against P. xylostella at 6.25 mg/L, while pyridalyl showed 50% insecticidal activity at the same concentration The field trials result of the insecticidal activities showed that compound I as a 10% emulsifiable concentrate (EC) was effective in the control of P. xylostella at 75-150 g a.i./ha, and the mortality of P. xylostella for treatment with compound 10e at 75 g a.i./ha was equivalent to pyridalyl at 105 g a.i./ha.
