Abstract:

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.

Key words: potato scab disease, Streptomyces scabies, pathogenic mechanism, chemical control, agricultural control, biological control
