Abstract
The present study, conducted at the College of Agriculture, Latur during 2023-2024, explores the viability of using fruit waste-derived media as a cost-effective alternative to conventional media for the growth of plant pathogens. The research focuses on the growth performance of Pseudomonas fluorescens, Fusarium oxysporum f. sp. udum, and Sclerotium rolfsii on media prepared from fruit peel of eight fruits (Banana, Pineapple, Papaya, Orange, Guava, Pomegranate, Dragon fruit, and Sapota). These fruit-based media were compared to traditional Nutrient Agar (NA) and Potato Dextrose Agar (PDA). Results revealed that Sclerotium rolfsii showed maximum growth on Papaya Dextrose Agar, while Pseudomonas fluorescens exhibited the most robust growth on Banana, Papaya and Dragon Fruit Dextrose Agar. Fusarium oxysporum f. sp. udum demonstrated the highest radial growth on Banana Dextrose Agar. The study also observed that fruit-based media significantly reduced costs compared to Potato Dextrose Agar and Nutrient Agar making them a sustainable and accessible option for microbiological research, particularly in resource-limited environments.
