Abstract

Tomato (Lycopersicon esculentum Mill.) is one of the most remunerative and widely grown vegetables in the world.  This crop is affected by major fungal pathogens (viz., early blight, late blight, wilt, collar rot, damping off and powdery mildew), among them early blight (Alternaria alternata) is considered as most important one. Among the fungicide tested, the majority were found effective in inhibiting the radial growth of test fungus and highest inhibition was recorded in Prochloraz 24.4 + Tebuconazole 12.1 EW, fluxapyroxad 250 g/l + pyraclostrobin 250 g/l SC at 500 and 1000 ppm,  pyraclostrobin 13.3 + epoxiconazole 5 SE and azoxystrobin 18.2 + difenoconazole 11.4 SC at 1000 ppm concentration and were found equally effective and completely inhibited the mycelial growth of A. alternata in vitro and proved significantly superior over rest of the treatments.
