Synthesis of Pyridalyl and Its Insecticidal Activities
Pyridalyl was synthesized by employing p-hydroquinone and 1,1,1,3-tetrachloropropane as starting materials, the structure of the target compound was confirmed by 'H NMR. Indoor insecticidal activity test showed that pyridalyl had excellent insecticidal activities against diamondback moth (Plutella xyllostella), beet armyworm (Spodoptera exigua) and armyworm (Mylhimna separate), in which the insecticidal rate to beet armyworm at 2.5 mg/L was 100%.
