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。
Myrica capensis is caused by the attack of bacteria (Pseudomonas syringnc pv. Myricae). Through the 1983 ~ 1986 experimental studies show that the bacteria mainly lurking in the branches of the tumor in the winter, early May the following year to late June, spill bacteria in the surface of the tumor, the rain spread, invasion from the wound, the incubation period 30 ~ 35 days. According to the results of indoor pharmacodynamics, the best antibacterial effect of 1000 ppm antimicrobial agent 402 emulsifiable concentrate is 1000 ppm, followed by 20% Ye Qing double wettable powder 400 ppm. Orchard pharmacy control test results show that the tree has been susceptible to take the removal of the tumor with 80% antimicrobial agent 402 EC 50 to 100 times or 20% Ye Qing double wettable powder 50 to 100 times the liquid brushing wounds were good The effect of the order. In the spring before the shoot, cut a small tumor with a long spray after spraying 0.5% lime-type Bordeaux mixture, with the protection of school stems to prevent the expansion of the role of disease spread.
