摘要： 三环锡对棉红蛛蜘的成螨、若螨和幼螨都有很好的毒效.在低剂量下,杀卵活性低,但是通过残留接触可有效地杀死新孵化的幼螨.20%三环锡稀释2000倍在果园中喷雾,可有效地防治山楂红蜘蛛、苹果红蜘蛛和柑桔红蜘蛛,而且有很好的残留效果,用药后30天,持续效果仍达90%以上.

Abstract: Tricyclohexyl tin hydroxide is very effective control newly hatched larvae, nymphs and adults of T.urticue.The ovicidal activity is very low at low dosage. However, it is very effective in killing the newly hatched larvae by residual contact action. Tricyclohexyl tin hydroxide is very effective control the haw red spider mite, the European red spider mite,and the citrus red spider mite, when a diluent of 20% formulation(2000 times by water)is sprayed in orchard.lt showed satisfactory residual activity in field test. Lasting effect were 90% after application 30 days.
