| 中文摘要: |
| 为筛选防治柑橘沙皮病的高效低毒药剂, 连续两年进行了新型复配药剂50%克菌丹·啶氧菌酯水分散粒剂防治柑橘沙皮病的田间药效试验, 对该药剂防治柑橘沙皮病的效果及安全性进行了评价。两年的试验结果表明:50%克菌丹·啶氧菌酯水分散粒剂有效成分用量625 mg/kg对柑橘沙皮病具有较好的防治效果, 2018年药剂处理两次后对柑橘叶片和果实沙皮病的防治效果分别为78.46%和76.84%, 2019年药剂处理两次后对柑橘叶片和果实沙皮病的防治效果分别为78.79%和75.59%, 显著优于对照药剂80%克菌丹水分散粒剂800 mg/kg的处理, 优于对照药剂22.5%啶氧菌酯悬浮剂150 mg/kg的处理。50%克菌丹·啶氧菌酯水分散粒剂对柑橘安全, 值得应用于柑橘沙皮病防治的示范与推广。 |
| 英文摘要: |
| To screen the high-efficacy and low-toxicity fungicide for controlling Diaporthe citri, a two-year consecutive field experiment was conducted to evaluate the efficacy and safety of captan·picoxystrobin 50% WG against D.citri. The results showed that captan·picoxystrobin 50% WG at 625 mg/kg had a good control effect against D.citri on citrus leaves and fruits, the control efficacy of fungicide treatment twice in 2018 reached 78.46% and 76.84%, 78.79% and 75.59% in 2019, respectively, which was significantly superior than that of captan 80% WG at 800 mg/kg, and better than that of picoxystrobin 22.5% SC at 150 mg/kg. Captan·picoxystrobin 50% WG is safe for citrus, which is worthy of demonstration and promotion D. citri control. |
