Developed for use in Asiablight training and regional surveillance, the protocols enable laboratories to generate comparable baseline sensitivity data and monitor changes in fungicide efficacy over time. By supporting evidence-based disease management, the document contributes to improved late blight control, reduced fungicide misuse, and enhanced resilience of potato production systems.application/pdfOpen Accessphytophthora infestansplant disease controlpotatoesSolanum tuberosumReport
