Abstract: Influence of various grain and nut sourced culture media [viz. Oatmeal agar (OMA), Whet meal agar(WMA), Black wheat agar (BWA), Green gram agar(GGA), soybean meal agar(SMA), Pistachio agar (PIA)] were tested to evaluate the influence of mycelial growth and sporangial production of Phytophthora nicotianae var. parasitica. Among the culture media tested, both PIA and SMA agar exhibited maximum colony growth (90.00 mm) followed by GGA (89.00 mm), WMA (88.00 mm), OMA(86.66) and BWA(84.66). The mycelial growth pattern was similar in all the cultures with a slightly radiate pattern. But the SMA exhibited the highest sporangia production in water.
