Specified concentrations of different chemicals were tried as the sclerotial treatment for the duration of 10, 20 and 30 minutes separately. Treated sclerotia were planted on PDA medium in the Petridishes. Sclerotia treated in distilled water for different duration were kept as check. Colony diameter of fungal growth was measured in all treatments and the data very much clarify that treatment of sclerotia even at 10 minutes of the higher tested concentration proved completely inhibitory against the fungus in case of all tested chemical excpt Acetic acid + Zinc sulphate (1:1), Thiram and Indophil M-45.
