Abstract:

In vitro evaluation of some fungicides (systemic and non-systemic) against twenty different Indian isolates of Sclerotium rolfsii were tested on potato dextrose agar medium by using poisoned-food technique and per cent growth inhibition was recorded at ranging from 125, 250 and 500 ppm for systemic; and 500, 1000 and 2000 ppm for non-systemic, respectively. For fungicides evaluation, the isolates were grouped on the basis of growth rates on Petri plates with 90 mm diameter as fast (5-6 days), medium (8-10 days) and slow growing isolates (12-15 days) respectively. Among systemic fungicides, difenconazole and hexaconazole have completely inhibited growth of all the isolates of the S. rolfsii. While carbendazim was less effective in growth inhibition of S. rolfsii at all tested concentrations. Among non-systemic fungicides, mancozeb was more effective than chlorothalonil. All the fungicides tested effectively inhibited the growth of S. rolfsii isolates. Among these fungicides, hexaconazole and difenconazole (systemic) were superior at 125 ppm and proved the most effective for suppressing the growth of S. rolfsii isolates followed by mancozeb and chlorothalonil (non-systemic).
