摘　　要：为了有效防治苹果腐烂病,选取噻霉酮、寡雄腐霉、甲基硫菌灵3种作用方式不同的涂抹剂作为苹果腐烂病进行试验药剂对比试验。结果表明:在苹果腐烂病发生严重的果园3种涂抹剂均有一定的防治效果。噻霉酮处理的防效最好,对病疤复发防效和新增病疤防效均明显高于另两种涂抹剂,防效分别为89.78%和87.84%;寡雄腐霉处理基本能够控制苹果腐烂病的发生,对苹果腐烂病病疤重犯的防效为76.84%,略低于甲基硫菌灵防效。寡雄腐霉对苹果腐烂病新增病疤防效为71.36%,明显低于甲基硫菌灵的药效。腐烂病防治适期应在早春苹果发芽前病害发生之前或发生初期,试验期间未发现各供试药剂对果树有不良影响。In order to effectively control the apple rot disease,three painting reagents were used for field control effect comparison of apple rot disease, such as Benziothiazolinone, Pythium oligandrum, Thiophanate-methyl. The results showed that the control effect of Benziothiazolinone was the best ,control efficiency of recurrence and control efficiency of new disease sear were 89.78% and 87.84% respectively. It was suggested that Benziothiazolinone should be used to control the rot in practice. The control effect of Pythium oligandrum respectively were 76.84＆ and 71.36% ,which was slightly lower than the value of thiophanate-methyl.
