马铃薯疮痂病的致病机制及防治研究进展

致病性疮痂链霉菌(Streptomyces scabies)引发的马铃薯疮痂病是世界范围内广泛存在的土传细菌性病害,难以防治。为了制定更有效的防治策略和开发新型药剂,使其得到更有效的控制,本文归纳了S. scabie产生的致病毒素thaxtomins和植物激素（细胞分裂素、生长素和乙烯）对S. scabies致病进程的影响;总结了防治马铃薯疮痂病所采用的主要化学药剂、农业技术手段和微生物源制剂,并分析了各种防治方法的优缺点。指出深入探究马铃薯疮痂病的致病机制对开发新型马铃薯疮痂病防治剂具有重要意义,微生物复合菌剂的研发和应用是今后防控马铃薯疮痂病的重要方向,认为将化学防治、农业措施与复合微生物菌剂三者联用能更好的防控该病害的发生和危害,对马铃薯产业的可持续发展具有重要意义。

Pathogenic Mechanism and Control Method of Potato Scab: Research Progress

Potato scab caused by the pathogenic Streptomyces scabies is a soil-borne bacterial disease that exists worldwide, and it is difficult to control. In order to formulate more effective control strategies and develop new types of agents to control potato scab more effectively, the effects of virogen thaxtomins produced by S. scabie and plant hormones (cytokinins, auxins and ethylene) on the pathogenic process of S. scabies were concluded, the main chemical agents, agricultural techniques and microbial source preparations used for controlling potato scab disease were summarized, and the advantages and disadvantages of various control methods were analyzed. It was pointed out that to dive deeper into the pathogenic mechanism of potato scab was of great significance to develop new control agents against potato scab, and the development and application of compound microbial inoculants should be an important direction to control potato scab in the future. It is believed that the combination of chemical control, agricultural measures and compound microbial agents can prevent and control the occurrence and damage of potato scab, which is of great significance to the sustainable development of the potato industry.
