Temporal and spatial spread of groundnut rust (Puccinia arachidis Speg.) on groundnut sown at different dates over three seasons and two years were monitored to identify the dates of sowing that restricts apparent infection rate to a low level. From disease severity recorded at 10-day intervals, r was calculated using logistic and Gompertz transformations. Dates of sowing which had low infection rates in the Gompertz model (0.02 units) or less per day indicated slow progress of the disease. Although both models effectively linearized the disease proportions, Gompertz was more suitable with lower variation in infection rates, standard errors of estimate, and higher correlation coefficient. Late sowing in the rainy season caused lower disease severity whereas in the winter and summer season, early sowing minimized the severity of disease incidence.

... Early sowing can facilitate the premature dispersal and germination of fungal spores, prompted by the advent of favourable temperatures and humidity levels. This phenomenon triggers an early emergence of the disease and increase the number of fungal cycles during the epidemic phase, thereby intensifying crop damages (Dawit and Andnew 2005;Das et al. 1999). Accordingly, postponing planting was shown to diminishes the impact of rust in peanut (Das et al. 1999), faba bean or pea (Eshetu et al. 2018;. ...

... Though step down analysis identify the maximum temperature, maximum relative humidity, bright sunshine hours, vapour pressure evening and soil temperature for groundnut rust and maximum relative humidity, bright sunshine hours and total rainfall for leaf spot. They directly favour the growth, multiplication and release and dispersal of conidia and urediospore in the crop canopy in fungicides applied plots (Das and Raj, 1998;Saha and Das, 2015). ...
