摘　　要：In order to screen out effective fungicides for controlling citrus canker,the control effects of 9 fungicides on Jinhong bingtang orange canker were studied.The results showed that 77%cupric calcium sulfate WP,30%copper oxychloride SC,46%copper hydroxide WG,30%thiodiazole-copper SC and 40%zinc thiazole SC had better comprehensive control effect on citrus canker,6%benziothiazolinone WG had an average effect,3%zhongshengmycin AS,2%kasugamycin AS and 33.5%oxine-copper SC had poor control effect.Therefore,fungicides could be used alternately or choose compounded preparation.In addition,adjuvants could be considered in use,which was an effective way to enhance efficacy,reduced dosage and delayed pesticide resistance.为筛选出适合柑橘溃疡病防治的有效药剂,研究了9种药剂对锦红冰糖橙溃疡病的防治效果。结果表明,77%硫酸铜钙WP、30%王铜SC、46%氢氧化铜WG、30%噻菌铜SC、40%噻唑锌SC对柑橘溃疡病的综合防治效果较好,6%噻霉酮WG一般,3%中生菌素AS、2%春雷霉素AS、33.5%喹啉铜SC的防治效果较差。生产应用中,可以择优轮换使用,或选择复配制剂。此外,在药剂使用中可以考虑加入助剂,是增强药效、减少用药量、延缓抗药性产生的有效途径。
