摘要：Field experiments were conducted to study the influence of weather parameters on the incidence of pests and diseases in groundnut for 3 years i.e. 2004-05, 06-07 and 08-09 during rabi season at Agromet–cell, Agricultural Research Institute, Rajendranagar, Hyderabad. The data analyzes were pooled and analyzed statistically with weather parameters using correlation and regression techniques. Correlation studies showed significant positive relationship of thrips damage with morning and evening relative humidity, while Spodoptera litura damage was positively influenced by evaporation and age of the crop. Leaf spot and rust incidence was mainly influenced by maximum temperature, evaporation and age of the crop. The regression equations were developed for groundnut pest and diseases using linear and non-linear models. The coefficient of determination (R 2 ) was improved by 6 to 20% when non-linear regression equations were fitted. These models after validation will be utilized in issuing of agro advisories in the state
