Abstract: The physical factors like temperature and pH having impact on growth and sporulation of saprophytic pathogenic fungi. It is well known that groups of fungi have pH optimum, minimum and maximum for fungal growth. Depletion of physical factors directly impact on growth and sporulation of fungi lowering and high temperature fungal growth will be retarded but at optimum temperature stimulating fungal growth and sporulation. Temperatures from 250C to 300C were most favorable for the growth of pathogen. The highest growth of Alternaria porri, Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Colletotrichum circinans and Penicillium corymbiferum was recorded at 300C. Optimum pH 6.5 to 7.5 sporulation was good seen in Alternaria porri, Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Colletotrichum circinans and Penicillium corymbiferum. The pHranges 5 to 8 were found suitable to the growth of all the pathogenic fungi.

Keywords- Key words: physical factors temperature and pH, pathogenic fungal spores, PDA media.
