Powdery scab is a soil-borne disease that thrives in cool, moist conditions, causing unsightly lesions on potato tubers and galls on roots. Unlike other pathogens, 스폰 고스 포라 지하 can survive in soil for years as resting spores, making eradication nearly impossible. Recent studies indicate that climate change may exacerbate the issue, as fluctuating weather patterns create ideal conditions for spore activation (FAO, 2023). The disease is also the only known vector of potato mop-top virus (PMTV), which further reduces tuber quality and marketability. Despite its economic impact, PMTV rarely shows foliar symptoms, making early detection difficult (Charkowski, 2024). Symptoms and Spread Infected tubers initially develop purplish-brown, sunken lesions, 다음 raised pustules filled with spores. These pustules rupture, releasing spores into the soil, where they remain viable for over a decade (Ontario Ministry of Agriculture, 2023). The pathogen spreads through: Infected seed tubers오염된 토양 (via ...
