Studies conducted on the effect of systemic and non-systemic fungicides. Among the tested six systemic fungicides, Carbendazim is the most effective as they have inhibits the completely mycelial growth recorded of the test pathogen at 0.05, 0.1 and 0.2% concentration. The next best of Difenoconazole evaluated against Fusarium oxysporum f. sp. lentis, radial growth were found of (12.33mm and 82.38%), (11.66mm and 83.34%) and (9.33mm and 86.67%). Thiophanate-methyl was least effective which showed 18.66mm, 16.66mm and 15.00mm radial growth and 73.34, 76.67 and 78.57% inhibits mycelial growth observed at 0.05, 0.1 and 0.2% concentration. Its six non systemic fungicides were tested, Thiram was found to be most effective and recorded least mycelial growth11.33mm, 10.33mm and 8.33mm with highest mycelium inhibition 83.81, 85.24 and 88.10 percent at 0.05, 0.1 and 0.2% concentration against Fusarium oxysporum f. sp. lentis. The Copper oxychloride was next best fungicides found (18.00mm and 74.28%), (16.66mm and 76.185) and (13.33mm and 80.95%). The Zineb was comparatively least effective observed (44.33mm and 36.66%), (43.33mm and 38.10%) and (41.66mm and 40.48%) at 0.05, 0.1 and 0.2% concentration, against Fusarium oxysporum f. sp. lentis as compared to untreated control.
