Monosporic isolates of Colletotrichum gloeosporioides were made from Punica grantum and one suitable isolate was selected for further work on carbon nutrition. Preliminary experiments showed that a pH value of 5, a temperature of 32°C and a period of 14 days were optimum conditions for the growth of this pathogen.Out of 41 carbon compounds tested, the pathogen showed excellent growth on starch, maltose, melibiose, dextrose, sucrose, raffinose, and dulcitol; good on tartaric acid, mannose, galactose, fructose, mannitol, and castor oil; fair on inulin, isopropyl alcohol, coconut oil, and pectin; poor on sorbose, n-butyl alcohol, arabionose, maleic acid, ethyl alcohol, succinic acid, citric acid, ribose, and malic acid, and no growth on the rest of the carbon compounds. In general, compounds which supported the best mycelial growth, yielded excellent or good sporulation of C. gloeosporioides and vice versa.
