Optimizing conditions for growth and sporulation of Alternaria macrospora MKP1: a biocontrol agent of Parthenium weed

摘要: During a series of surveys for natural enemies Parthenium hysterophorus , leaf blight pathogen was isolated from the affected parts parthenium following standard isolation techniques using potato dextrose agar (PDA) media. Koch’s postulates were performed and found satisfactory isolate proved to be pathogenic this weed. On basis cultural, morphological molecular characteristics, identified as Alternaria macrospora MKP1. The growth fungal is known influence by environmental factors such temperature, relative humidity pH. Therefore, main objective study optimization cultural conditions sporulation A. results present investigation indicated that physical greatly pathogen.
