Effect of Media Composition on Vegetative and Reproductive Growth of Alternaria Brassicicola and Bipolaris Sorokiniana

Experiments were conducted to evaluate the effect of some culture media on the vegetative and reproductive growth of Alternaria brassicicola and Bipolaris sorokiniana. Twenty one (21) treatment combinations each with three replications were employed. Potato Dextrose Agar (PDA) was used as the basic growth medium in this study. Supplementation with different plant extracts with this medium produced differential growth and sporulation of the tested fungi. PDA media supplemented with mustard leaf extract showed significantly highest vegetative growth (7.8 cm) and PDA with the combination of mustard leaf, tomato fruit, carrot fruit and cabbage leaf extracts showed the highest sporulation (11×105 spores/ml) of A. brassicicola. In case of B. sorokiniana, the highest vegetative growth (7.4 cm) and highest sporulation (45×104 spores/ml)…
