| 中文摘要: |
| 柑橘溃疡病作为潜伏时间长、传染能力强的细菌性病害,严重制约了我国柑橘行业的发展。为了筛选合理的施药时期与高效的防控药剂,进而为全国的柑橘种植行业提供防控药剂及策略。在万州塔罗科血橙(玫瑰香橙)果园评价了38种杀菌剂于春梢期、谢花2/3时、幼果期3次施药后对于春梢、夏梢以及果实上溃疡病的田间防治效果。结果表明：84%王铜水分散粒剂、 77%硫酸铜钙可湿性粉剂、 27.12%碱式硫酸铜悬浮剂、 21%中生.乙酸铜可湿性粉剂、 20%噻菌铜悬浮剂、 3%噻霉酮微乳剂、 45%春雷.喹啉铜悬浮剂、 47%春雷.王铜可湿性粉剂、 25%溴硝醇水分散粒剂、 46%氢氧化铜水分散粒剂对春梢、夏梢以及果实的防效超过了90%,可采取中高倍数在适宜时间段喷施进行防控柑橘溃疡病。 |
| 英文摘要: |
| Citrus bacterial canker, a bacterial disease characterized by a long incubation period and strong infectivity, severely hampers the development of China""s citrus industry. To identify optimal application timing and highly effective control agents, thereby providing nationwide citrus growers with control strategies and chemical solutions, In a Tarocco blood orange (Rosa-scented orange) orchard in Wanzhou, the field efficacy of 38 fungicides against canker disease on spring shoots, summer shoots, and fruit was evaluated after three applications: during spring shoot growth, when two-thirds of flowers had fallen, and during the young fruit stage. Results indicate: 84% copper hydroxide water-dispersible granules, 77% copper sulfate calcium wettable powder, 27.12% basic copper sulfate suspension, 21% Zhongsheng. Copper Acetate Wettable Powder, 20% Copper Thiofosate Suspension, 3% Thiocycloxuron Microemulsion, 45% Chunlei. Quinoline Copper Suspension, 47% Chunlei. Wangtong wettable powder, 25% bromonitrophenol water-dispersible granules, and 46% copper hydroxide water-dispersible granules demonstrate over 90% efficacy against spring shoots, summer shoots, and fruit. These formulations can be applied at medium to high dilutions during appropriate time windows to control Citrus bacterial canker. |
