Note: 1 = No pathogen attack observed; 2 = less than 5% of leaf area affected; 3 = 5%–20% of leaf area affected with some chlorosis; 4 = 21%–50% of leaf area affected, significant leaf chlorosis; 5 = 51%–80% of leaf area leaves affected, severe leaf chlorosis; 6 = 81%–100% of leaf area with complete leaf chlorosis. All values mean of six plants. Values followed by the same letter are not statistically significant (P ≤ 0.05) according to LSD.
