Abstract : Logistic and Gompertz growth models were used to describe the pattern of powdery mildew (Oidium mangiferae) 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 than in Amrapali. Maximum rate of disease growth was between seventh and eighth weeks after the initiation of the disease. This modelling effort is expected to be useful in developing strategies for the efficient management of powdery mildew disease of mango.
