ASSESSMENT OF ANTIFUNGAL PROPERTY OF GARLIC EXTRACTED IN DIFFERENT SOLVENTS AGAINST THE LEAF SPOT AND FLOWER BLIGHT OF MARIGOLDRakesh Roshan Satapathy and Kartik Chandra Sahoo
Alternaria zinniae causes marigold leaf spot and blossom blight in tropical and subtropical climates, which reduces yields by 50â60%. Agronomic control techniques are challenging to deploy, and chemical controls may affect ecosystems. This study aimed to investigate the effectiveness of various solvent extractions of garlic against the test pathogen. Methanol, ethanol, acetone, acetic acid, chloroform, and water extraction of garlic were tested against the test fungus at 10% and 20% concentrations for this purpose. We discovered that the ethanol extract of garlic showed an inhibition of 87.84% at 10% concentration, followed by the methanol extract of garlic (86.49%). Garlic solvent extraction using acetone and acetic acid revealed an inhibition of 85.81% and 83.11%, respectively. These outcomes were all on par. Garlic solvent extraction in chloroform, however, had the least inhibition. In the instance of a 20% concentration, the same tendency had been noted. Allium sativumâs ability to combat marigold flower disease may be explained by the presence of the phenol component, though more research is necessary. The effectiveness of garlic solvent extraction against marigold flower blight could also be tested in the field.
