Eight carbon,ten nitrogenous sources and various pH regimes were tested for their effect ongrowth and sporulation of C.gloeosporioides. Out of eight carbon sources tested, starch and xylloseproved to be the best for the growth and sporulation followed by glucose andsucrose. Out of ten different nitrogenous sources tested, potassium nitrateproved to be the best for the growth and sporulation of the pathogen. Studieson pH revealed that fungus produced the maximum dry mycelial weight andsporulation at pH 5.5 and pH 6.5 in liquid media respectively. Thus the use ofundegraded organic manures, potassium nitrate bases fertilizers and slightly acidicsoil favors the disease.
