Abstract : The pattern of changes in incidence of vegetative and floral malformation of 'Dashehari' mango with host age was expressed mathematically. The disease progress curve was modelled using a set of experimental data at Faizabad, Uttar Pradesh, India, in 2000-01. The model was tested with a set of data obtained at Lucknow in 1979 and the structure of the model was validated. The close fit between the modelled and experimental curves showed the main trend of the epidemic. The incidence of vegetative malformation was maximum in 5-year-old plants then declined thereafter. The floral malformation up to initial 11 years of age showed an increase then a curvilinear decrease.
