Logistic and Gompertz growth models were used to describe the pattern of powdery mildew development on mango cultivars Dashehari and Amrapali. Quantitative information about the parameters concerning intrinsic infection rate and maximum mildew severity had been obtained. The area under disease progress curve (AUDPC) was higher in Dashehari and than in Amrapali. Maximum rate of growth of the disease was found to be betwween 7th and 8th weeks after the intiation of the disease. This moddelling effort is expected to be useful in developing strategies for the efficient management of powdery mildew disease of mango.
