| 中文摘要: |
| 四川安岳柠檬园管理水平较为粗放，黑斑病、炭疽病、疮痂病以及灰霉病等发生严重，其中砂皮病尤其严重。为了筛选更有效的柑橘砂皮病防控药剂，进而为安岳柠檬及全国柑橘生产提供防控砂皮病的药剂及策略，在安岳县尤力克柠檬基地评价了32种杀菌剂于谢花期、幼果期以及果实膨大期3次用药后对于夏梢与果实上砂皮病菌的田间防治效果。结果表明，40%苯醚甲环唑悬浮剂（杭州宇龙化工有限公司）3 000倍液、60%唑醚·代森联水分散粒剂（广东天禾农资股份有限公司）4 000倍液、25%吡唑醚菌酯悬浮剂（安徽化星化工有限公司）1 500倍液、70%甲基硫菌灵可湿性粉剂（山东邹平农药有限公司）1 000倍液以及75%锰锌·嘧菌酯水分散粒剂（印度联合磷化物有限公司）500倍液对夏梢叶片与果实上砂皮病的防治效果接近或超过90%，且未见发生炭疽病、黑斑病、疮痂病和灰霉病。不同厂家的代森锰锌的防治效果差异较大，先正达(苏州)作物保护有限公司和利民化学有限责任公司生产的80%代森锰锌可湿性粉剂（400倍液）对夏梢叶片与果实上砂皮病的防治效果较好，且其他病害中仅见疮痂病发生。研究结果可为柑橘生产中有效防控砂皮病提供参考。 |
| 英文摘要: |
| The management level of lemon orchards in Anyue, Sichuan Province is relatively rough, and diseases such as Phoma citricarpa, Colletotrichum gloeosporioides , Elsinoe fewcetti and Botrytis cineria Pers occur seriously, among which Diaporthe citri is particularly severe. In order to screen more effective fungicides for citrus scab control and provide control agents and strategies for scab in Anyue lemons and citrus production across the country, the field control effects of 32 fungicides on scab on summer shoots and fruits were evaluated in the Eureka lemon base of Anyue County at three application times: after flowering, during the young fruit stage and during the fruit expansion stage. The results showed that 40% tebuconazole suspension concentrate (Hangzhou Yulong Chemical Co., Ltd.) at 3,000 times dilution, 60% difenoconazole + mancozeb water dispersible granules (Guangdong Tianhe Agricultural Chemical Co., Ltd.) at 4,000 times dilution, 25% pyraclostrobin suspension concentrate (Anhui Huaxing Chemical Co., Ltd.) at 1,500 times dilution, 70% thiabendazole wettable powder (Shandong Zouping Pesticide Co., Ltd.) at 1,000 times dilution and 75% mancozeb + pyraclostrobin water dispersible granules (United Phosphorus Limited, India) at 500 times dilution had control effects on scab on summer shoot leaves and fruits close to or exceeding 90%, and no anthracnose, Phoma citricarpa, Colletotrichum gloeosporioides , Elsinoe fewcetti and Botrytis cineria Pers was observed. The control effects of different manufacturers'' mancozeb + manganese zinc were significantly different. The 80% mancozeb + manganese zinc wettable powder produced by Syngenta (Suzhou) Crop Protection Co., Ltd. and Limin Chemical Co., Ltd. (400 times dilution) had better control effects on Diaporthe citri on summer shoot leaves and fruits, and only Elsinoe fewcetti was observed among other diseases. The research results can provide a reference for the effective control of scab in citrus production. |
