Abstract: Three Systemic fungicides were evaluated against four isolates (Fv SC-01 to Fv SC-04) of Fusarium verticillioides in vitro condition to develop effective management strategies for post flowering stalk rot (PFSR) of specialty corn caused by F. verticillioides. Bavistin and saaf were found most effective inhibited 100% mycelial growth of pathogen in vitro at different concentrations@ 200, 400 and 600 ppm. Tebuconazole also showed complete inhibition of the mycelial growth at 400 and 600 ppm concentration, while at 200 ppm concentration it caused 97.80, 98.0, 98.33 and 98.55 per cent inhibition (Fv SC-01, 02, 03 and 04) of all isolates respectively.
