The paper deals with some cultural and physiological studies of a strain ofPhytophthora palmivoraButler, causing fruit rot ofAchras sapota L. Among the various culture media studied, oat meal, corn meal, lima bean and rice meal agars were the best ones, with abundant growth and sporulation of the organism. Lactose, galactose, dextrin and glycogen were the best sources of carbon. Among the various nitrogenous compounds studied, ammonium phosphate (monobasic), ammonium sulphate, ammonium tartrate, ammonium lactate, asparagin, glycine and glutamic acid were the best ones utilized by the organism. A pH of 5.9 was found to be the optimum for the growth and sporulation.
