The role of weather forecastes such as temperature, rainfall and relative humidity were studied on the development and spread of black pepper (Piper nigrum L.) foot rot disease in Kamataka. The temperature range of 18.6–22.5°C coupled with relative humidity of 95 per cent and well distributed rainfall supported maximum disease development. During 1996 and 1997 studied the average maximum incidence of 28.6 and 25.4 per cent, respectively was recorded in the month of August positively related with relative humidity I (r = 0.754) and II (r = 0.778) of 95, 75 and 94, 85 per cent respectively. However, correlation with maximum temperature was significant imd negative (r = 0.728p). In multiple regression anaiysis positive regression co-efficient (r = 9.6545 and 1.4487), significant negative regression was recorded with rainy days, RH-I and RH-II. Thus, study proved that management practices could be formulated based of weather forecasters atleast a season leadtime in a geographical area.
