| 摘 要： | 通过对"锦丰"梨园梨锈病发生情况调查、梨锈病侵染过程中生态因子影响的研究、梨锈病发生、发展和侵染特征的观察及不同药剂和施药时期对梨锈病防治效果的影响试验,了解了梨锈病侵染全过程和各时期侵染特征;3～10d叶龄的梨叶锈病侵染最重;降水量和空气相对湿度是影响梨锈病发生的关键因子;有效成分为三唑酮、氟硅唑和苯醚甲环唑的杀菌药剂可作为治疗梨锈病的首选药剂,并以病斑出现后1～5 d为治疗梨锈病的最佳时期.

| Abstract: | Based on the investigation of occurrence of pear rust in Jinfeng pear orchard,ecological factors during infection of Gymnosporangium haraeanum Syd.and control efficiency of different pesticides in different stages were studied,and infection process of G.haraeanum and infection characteristics in different stages were made clear,which indicated that infection of 3~10 days leaves were most severe,and precipitation amount and air relative humidity were essential factors.And the optimum pesticide was bactericid... |
