摘　　要：为筛选出生产上防治柑橘砂皮病的理想药剂,本研究开展了4种吡唑醚菌酯复配剂及其单剂对柑橘砂皮病的田间药效对比试验。结果表明,4种复配剂中30%吡唑醚菌酯·苯醚甲环唑悬浮剂防效最好,40%吡唑醚菌酯·喹啉铜悬浮剂和30%吡唑醚菌酯·甲基硫菌灵悬浮剂次之,40%吡唑醚菌酯·王铜悬浮剂略逊。4种吡唑醚菌酯复配剂可用于防治柑橘砂皮病,30%吡唑醚菌酯·苯醚甲环唑悬浮剂、30%吡唑醚菌酯·甲基硫菌灵悬浮剂、40%吡唑醚菌酯·王铜悬浮剂、40%吡唑醚菌酯·喹啉铜悬浮剂的推荐有效成分使用剂量分别为100~150、200~300、400~500及200~267 mg/kg。在柑橘谢花后、幼果期、果实膨大期各施药1次,防效为77.63%~85.20%。To screen out the effective fungicide for controlling citrus melanose in production,field trial was used to evaluate the control effect of 4 types of pyraclostrobin mixtures and single treatments on citrus melanose in this study.The results showed that control effect of pyraclostrobin·difenoconazole 30%SC was the best,followed by pyraclostrobin·oxine copper 40%SC and pyraclostrobin·thiophanate-methyl 30%SC,pyraclostrobin·copper oxychloride 40%SC had the lowest control effect.The four types of pyraclostrobin mixtures had good effect on citrus melanose.Recommended usages of pyraclostrobin·difenoconazole 30%SC,pyraclostrobin·thiophanate-methyl 30%SC,pyraclostrobin·copper oxychloride 40%SC and pyraclostrobin·oxine copper 40%SC were 100-150,200-300,400-500 and 200-267 mg/kg,respectively.The four fungicide were applied once after anthesis,young fruit stage and fruit expansion stage,the control effects were 77.63%-85.20%.
