摘    要:T-751(0-甲基-o-苯基-s-正丙基硫代磷酸酯)对粘虫具有高速击倒活性,在所试验的5种杀虫剂中,T-751对粘虫击倒最快。在14·11mg/m2的剂量下,KT50值为5.32分钟,比杀螟松、喹噁磷分别高8倍和1倍。T-751对棉铃虫的击倒活性也是所试验的杀虫剂中最快的。T-751对粘虫具有胃毒和触杀活性,不具有内吸作用。

关 键 词:不对称硫代磷酸酯  粘虫  棉铃虫

Abstract:T-751, O-methyl -O-phenyl -S- n- propyl phosphorothioate has high knockdown activityto the armyworm, Mythimna separata (Walker). The knockdown activity of T-751 to the armywormis the fastest in the 5 tested insecticidcs. KT50 value of T-751 is 5.32 minutes at dose of 14. 11mg/m2. It is about 8-fold and l-fold faster than Sumithion;and Quinalphos respectively. The knockdowaactivity of T-751 to the cotton bollworm, Hcliolhit armigera Hiibner, is the fastest in the tested iu-secticides. T-751 possesses stomach poison and contact poison to the armyworm. but dccs not havesystemic activity.
Keywords:asymmetric phosphorothioate  Mythimna separata (Walker)  Heliothis armigera (H■bner)
