Effect of fungicides and plant extracts on the sporulation and spore germination per cent of A. sesami

Abstract

Laboratory studies were conducted to study the effect of different fungicides and plant extracts on the sporulation and spore germination per cent of Alternaria sesami. The minimum mycelial growth was observed on Babool leaf extract amended medium whereas minimum sporulation on Babool, Neem and Gajar Grass. Spore germination was the minimum on Gajar grass leaf extract amended medium. In inhibition of mycelial growth Propiconazole was most effective whereas Propiconazole, Hexaconazole, Tebuconazole, Difenoconazole and Mancozeb were most effective in inhibition of sporulation at tested concentrations. Spore germination was most inhibited by Propiconazole.
