In vitro evaluation of some fungicides against Indian isolates of Sclerotium rolfsii Sacc. [Teleomorph: Athelia rolfsii (Curzi) Tu & Kimbrough]

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.
