Systemic acquired resistance inducing chemicals mitigate black scurf disease in potato by activating defense-related enzymes.

The potato, being an underground vegetable crop, faces consistent threats from soil- and tuber-borne fungal and bacterial pathogens. Black scurf and stem canker disease caused by the fungal pathogen Kuhn is a critical global concern in the potato cultivation system. In this study, we evaluated the disease mitigation potential of five systemic acquired resistance-inducing chemicals , salicylic acid, jasmonic acid, -aminobutyric acid, -aminobutyric acid and hydrogen peroxide (HO).
