摘要： 为筛选对苹果斑点落叶病具有良好防治效果的杀菌剂，以‘首红’苹果为材料，对苹果斑点落叶病进行14种药剂的田间药效试验。结果表明：10%苯醚甲环唑WG、430 g/L戊唑醇SC和70%丙森锌WP防治苹果斑点落叶病的效果最好，明显高于其他药剂。2013和2014年春梢期的防效分别为81.65%、81.24%、79.97%和82.36%、86.14%、83.42%，秋梢期防效分别为76.22%、77.83%、73.84%和81.80%、82.18%、75.58%。其次为50%克菌丹WP、50%嘧菌环胺WP和10%多抗霉素WP，在防治苹果斑点落叶病上也表现出较好的效果。春梢期防效分别为78.35%、78.17%、77.34%和81.89%、82.03%、81.88%，秋梢期的防效分别为73.47%、72.58%、74.45%和78.73%、74.69%、77.44%。80%代森锰锌WP对苹果斑点落叶病的防治效果较差，均低于其他药剂。方差分析表明，三唑类杀菌剂苯醚甲环唑与保护性杀菌剂代森锰锌处理间的防效差异在2年的试验结果中均显著。

Abstract: Based on the field experiments of 2013-2014, the ‘Red Chief’ apple was used for studying the control efficiency of fourteen fungicides against apple alternaria leaf spot. The results showed that the effect of 10% difenoconazole WG, 430 g/L tebuconazole SC and 70% propineb WP against apple alternaria leaf spot were the best. In 2013 and 2014, the control effects of the three treatments were 81.65%, 81.24%, 79.97% and 82.36%, 86.14%, 83.42% respectively in spring-growth and were 76.22%, 77.83%, 73.84% and 81.80%, 82.18%, 75.58% respectively in autumn-growth. The control efficiency of 50% captan WP, 50% cyprodinil WP and 10% polyoxin WP against apple alternaria leaf spot were also satisfying. In 2013 and 2014, the control effects of the three treatments were 78.35%, 78.17%, 77.34% and 81.89%, 82.03%, 81.88% respectively in spring-growth and were 73.47%, 72.58%, 74.45% and 78.73%, 74.69%, 77.44% respectively in autumn-growth. But the effect of 80% mancozeb WP against apple alternaria leaf spot was poor and lower than other fungicides. By analysis of variance, significant difference was found between triazole fungicide 10% difenoconazole WG and protective fungicide 80% mancozeb WP in two years.
