摘　　要：比较了5种不同复配剂对苹果果实轮纹病的防效,结果表明:在田间推荐使用浓度下,5种药剂对苹果果实轮纹病均有较好的防控效果。70%福美双.甲基硫菌灵可湿性粉剂700倍液、600倍液,32.8%苯醚甲环唑.多菌灵可湿性粉剂2000倍液、1500倍液,30%多菌灵.戊唑醇可湿性粉剂800倍液、55%甲硫.锰锌可湿性粉剂600倍液,6%福.戊可湿性粉剂300倍液采收期和贮后30 d防效均在80%以上;而30%多菌灵.戊唑醇可湿性粉剂1000倍液、55%甲硫.锰锌可湿性粉剂800倍液,6%福.戊可湿性粉剂400倍液在采收期和贮后30 d防效稍低但均在75%以上。Effects of 5 mixture of fungicides on controlling Apple Ring Rot of fruit were compared, the results indicate that all 5 mixtures of fungicides have good control effects to the disease with recommended concentration. For 700× and 600× of 70% thiramothiophanate WP, 2 000× and 1 500× of 32.8% difenoconazoleocarbendazim WP, 800× of 30% carbendazimotebuconazole WP, 600× of 55% thiophanate-methylomancozeb WP and 300× of 6% thiramotebuconazole WP, the preventive effect are higher than 80% at the harvesting time and the 30th day after harvest, however the preventive effect are somewhat lower for 1 000× of carbendazimotebuconazole WP, 800× of thiophanate-methylomancozeb WP and 400× of thiramotebuconazole WP, but all are higher than 75%.
