| 4- -phenyl methane sulfonate(ZJ0967) as a novel insecticide was synthesized by using 4-chlorobenzoyl chloride,methoxybenzene,methane sulfonyl chloride,hydrazine hydrate,and 2-butanone as starting materials.The structure of ZJ0967 was confirmd by 1H NMR,MS and elemental analysis.Its insecticidal activity was evaluated.ZJ0967 exhibited higher insecticidal activity against Mythimna sepatara and Prodenia litura,followed by Plutella xylostella and Spodoptera exigua.The LC50 value against P.litura was 8.45(7.69~9.62)mg/L. The activity of ZJ0967 against P.litura was almost equivalent to that of tebufenozide,but lower than that of chlorfluazuron.Field trials showed that the control effect of ZJ0967(70%WG) against Prodenia litura was 88.6%~93.9% after seven days at the rate of 210~420 g a.i./hm2.No crop injury was observed at the dosage of the tests. |
