Abstract:
Pomegranate is an important commercial fruit crop of India, it is affected by many diseases caused by various pathogens, resulted in poor quality and quantity of fruits. Survey was conducted in southern Karnataka and found that, the maximum PDI of scab was observed in Tipturu (15.56 PDI) followed by Kanakapura (13.10 PDI) and Arasikeri taluk (9.49 PDI). The fungus S. punicae exhibited maximum radial growth of 90.00 mm on Oat Meal Agar. At temperature of 30 ⁰C with highest radial growth (79.33 mm) and dry mycelial weight (283.23 mg) was recorded and good sporulation at 25 ⁰C was noticed. Optimum pH for the growth of pathogen is 6.5 to 7.
