The current research was conducted to identify the causal pathogen and respective disease severity in 4 districts of province Punjab, Pakistan. The most prominent symptoms of disease included formation of purple to black spot (5-15 mm) with/without yellow margins especially on older leaves.

The greenhouse experiment revealed variation in pathogenicity of different pathogenic strains.   .. View More»
