Abstract:
Pigeonpea wilting caused by Fusarium udum has emerged as one of the biotic threats to profitable pigeon pea cultivation. An in vitro study was conducted on the effects of different media, pH values, and temperature on mycelial growth, sporulation, and mycelial dry weight of Fusarium udum. The test organism grew best on PDA and Richards agar out of his seven media tested. The optimal pH for growth of the test pathogens was 6.0 and 6.5, which showed excellent sporulation. Growth of F. Udum peaked at 30 °C after 7 days of inoculation and decreased sharply below 10 °C and above 35 °C
