Abstract: Onion (Allium cepa) (Latin 'cepa' = onion), also known as the bulb onion or common onion, is used as a vegetable and is the most widely cultivated species of the genus Allium.) crop is affected by number of pathogenic fungi, causing significant qualitative and quantitative losses. Therefore, present in vitro study was conducted to asses bioefficacy of nine botanicals against pathogen Colletotrichum gloeosporioides, by applying Poisoned Food Technique. Experiments were planned and conducted with Completely Randomized Design (CRD) and all the treatments replicated thrice. The results revealed that all of the nine botanicals significantly inhibited mycelial growth of Colletotrichum gloeosporioides, over untreated control. However, Average mycelial growth inhibition ranged from 23.00 (A. squamosa) to 85.55 (A. sativum) per cent. However, it was highest with A. sativum (85.55%), followed by C. longa (70.76%), A. indica leaves (69.37%), Z. officinale (56.92%), C. annum (55.82%), D. metal (53.00%), A. cepa (35.27%), and O. sanctum (24.87%).
