摘　　要：[目的]研究三苯基乙酸锡对水稻田间水绵的防除效果。[方法]2008~2009年分别采用不同剂量的25%三苯基乙酸锡WP进行水绵防除试验,分别于施药后10、20、30 d调查药效,比较不同处理的防除效果。[结果]25%三苯基乙酸锡WP对水稻安全,对水稻田间水绵的防除效果持久且稳定;施药后30 d,对水绵的防除效果仍保持在98.00%以上,各处理的防除效果均优于对照药剂96%硫酸酮晶体。[结论]25%三苯基乙酸锡WP对水稻田水绵的防除效果明显,推荐剂量以300~450 g/hm2为宜。[Objective] The aim was to study the prevention and control effect of Spirogyra communis in paddy fields by triphenyltin acetate.[Method] S.communis prevention and control experiments were conducted in 2008 and 2009 by applying different dose of 25% triphenyltin acetate WP,and then the effects of different treatments were inspected and compared 10,20 and 30 d after application.[Result] 25% triphenyltin acetate WP had lasting and stable effect in guaranteeing the rice safety and preventing and controlling S.communis.And the prevention and control effect of S.communis still maintained above 98.00% even at the 30th day after triphenyltin acetate application,whose effect was better than the that of the control herbicide of 96% copper sulfate crystals.[Conclusion] 25% triphenyltin acetate WP could effectively prevent and control S.communis,and the recommended dose is 300-450 g/hm2.
