Abstract
Prediction models play an important role in forecasting the disease progression in time. The rust of Teak, which was caused by Olivea tectonae, was predicted by Logistic model. For 1-2 year Teak, the estimated Per cent Disease Index (PDI) varied from 1.88 to 47.75 with coefficient of determination r=0.988 and 2.25 to 84.41 with coefficient of determination r= 0.952 for 3-6 year Teak saplings.
