Comprehensive Management Strategies for Controlling Potato Scab in Taiwan: Prevention, Cultural Practices, and Biological Control

Potato scab, caused by Streptomyces spp., poses a significant threat to global potato production, including in Taiwan where cultivation began in 1914. Although historically rare in the region, the disease has increasingly been problematic, particularly after a severe outbreak in 1995. This review synthesizes research on the etiology, transmission, and management of potato scab, highlighting its detrimental effects on yield and quality. Streptomyces spp., the primary pathogens persist in soil and infect tubers primarily through wounds or lenticels.
