| 摘 要： | 杨梅癌肿病是由细菌(Pseudomonas syringnc pv.myricae)侵害引起。通过1983～1986年的试验研究表明,病菌主要潜伏在枝干的病瘤内越冬,翌年5月上旬～6月下旬,于病瘤表面溢出菌脓,经雨水传播,从伤口侵入,潜育期30～35天。经室内药效测定结果,以80％抗菌剂402乳油1000 ppm抑菌效果最佳,其次为20％叶青双可湿性粉剂400 ppm。果园药剂防治试验结果表明,对已感病的树,采取切除病瘤后用80％抗菌剂402乳油50～100倍液或20％叶青双可湿性粉剂50～100倍液涂刷伤口,均有良好的治序效果。在抽春梢前,剪除长有瘤的小谈后喷0.5％石灰倍量式波尔多液,具有保护校干、防止病害扩展蔓延的作用。

| Abstract: | Bayberry bacterial gall is one of the major diseases of the bayberry tree in Zhejiang province.The pathogenic bacteria overwinter in the galls of the trunk.Galls begin to form in May and develop quickly in July.Studies on the chemical control showed that to brush the wounds with antibactericide "402" and to spray the branches with Bordeaux mixture was very effective in controlling the Bayberry bacterial gall. |
