摘　　要：对美国迈图高新材料集团开发的Silwet系列有机硅农用喷雾助剂杰效利、喜施和丝润在不同品种苹果上套袋前单独使用、与不同杀虫剂混用及套袋后单独使用的安全性进行了评价。结果表明:杰效利、喜施和丝润套袋前单独使用对不同品种苹果幼果安全性表现一致,不同参试浓度对"嘎啦"、"乔纳金"幼果均未产生药害,但在苹果"红富士"品种上,500～2 000倍产生药害,且药害程度随用量提高而增加;与48%毒死蜱EC混用及单独喷施毒死蜱,在幼果表面果点处均产生不同程度的药害;套袋后使用有机硅助剂对果实和果袋均无不良影响。Safety of three new type organosilicone spray adjuvants in Silwet series,developed by Momentive Performance Materials of America,were evaluated on apple.Before bag operation,Silwet 408,Silwet 806and Silwet 618presented the same results on various varieties of apples.The results showed that all three adjuvants showed no differences on apple varieties when applied individually before bag operation;chemical injuries showed neither on ‘Gala’ nor ‘Jonagold’,but damages on ‘Fuji’ with 500～2 000times dilution with increasing severity of injuries for higher chemical concentration.Adjuvants mixed with 48% chlorpyrifos and chlorpyrifos alone showed chemical injuries on the surface of apples;however,no injury showed on apple fruits or bags after bag operation when organosilicone adjuvants was applied.
