Abstract
The study aimed to assess the effectiveness of various plant extracts against Colletotrichum gloeosporioides in papaya. This investigation employed a completely randomized design and took place at the College of Agriculture in Pune-05 during the academic year 2021-22.Among the six plant extracts tested, garlic (Allium sativum) was found to be superior to the rest, exhibiting the minimum mycelium growth (5.30 mm) and the highest percentage inhibition (94.11%) at a 20% concentration. However, the drumstick leaf (Moringa oleifera) extract was the least effective, with the maximum radial mycelial growth of 44.00 mm (51.11% inhibition) observed. The study indicates that the radial mycelial growth of Colletotrichum gloeosporioides decreases with rise in the concentration of plant extracts.
