【摘要】 该试验以‘嘎拉’苹果为试材，开展几种杀菌剂对苹果斑点落叶病和褐斑病的防效试验。结果表明，67%唑醚·丙森锌SC 1 000倍和1 500倍液处理对苹果斑点落叶病的防效分别为89.46%和85.22%，对褐斑病的防效为96.50%和92.55%;25%吡唑醚菌酯SC 2 000倍+43%戊唑醇SC 4 000倍和25%吡唑醚菌酯SC 1 500倍+43%戊唑醇SC 3 000倍液处理对斑点落叶病的防效为81.07%和91.38%，对褐斑病的防效为84.97%和90.48%。均优于对照药剂百泰。试验说明67%唑醚·丙森锌SC，以及25%吡唑醚菌酯SC和富力库组合对苹果斑点落叶病和褐斑病具有良好的防治效果。更多还原

【Abstract】 In this experiment,the control efficiency of several fungicides against apple alternaria blotch and brown spot were conducted on apple cultivar ‘Gala’. The results showed that the control efficiency of 1000-fold and 1 500-fold 67% pyraclostrobin-antracol SC against apple alternaria blotch and brown spot were 89.46%,85.22%,96.50% and 92.55% respectively;The control efficiency of two treatments,2 000-fold 25% pyraclostrobin SC with 4 000-fold 43% tebuconazole SC and 1 500-fold 25% pyraclostrobin SC with 3 000-fold 43% tebuconazole SC,were 81.07% and 91.38% for controlling apple alternaria blotch,84.97% and 90.48% for controlling apple brown spot. The control efficiency of four treatments were better than control Cabrio Top. The experiment results illustrated that 67% pyraclostrobin-antracol SC and the combination of 25% pyraclostrobin SC with 43% tebuconazole SC have significant control effect against apple alternaria blotch and apple brown spot.更多还原
