Foot rot
-
Foot rot of tomato is an important disease which causes severe loss in tomato production. The present study was carried out to evaluate five bioagents and six fungicides against Sclerotium rolfsii. Among the five antagonists tested the maximum inhibition was observed in Trichoderma virens (67%) and contrarily, no inhibition was observed in Bacillus subtilis. Six fungicides viz., carbendazim, captan, tebuconozole, copper oxychloride, hexaconozole and Tebuconazole +Trifloxytrobin at different concentrations (50, 100, 150, 200, 250 and 500 ppm), were tested.

Morphological and cultural variability of S. rolfsii infecting tomato were studied on different solid and liquid media based on radial growth, topography, sclerotial number, diameter of sclerotia, test weight of sclerotial bodies and dry mycelial weight. Significant variability with reference to mycelial and sclerotial characters was observed on different media. This investigation revealed that the maximum mycelial growth was observed in Potato Dextrose Agar (9 cm) and more test weight (262 mg) of sclerotial bodies was recorded in Sabouraud’s dextrose agar.
