Incidence of stem rot disease of groundnut in relation to weather parameters in major groundnut growing areas of Telangana

Groundnut (Arachis hypogaea L.) is an important oilseed crop and the economic production of groundnut constrained by soil-borne diseases. Stem rot, caused necrotrophic fungus Sclerotium rolfsii, was most common disease in groundnut. A roving survey conducted major growing areas Telangana during kharif 2019 rabi 2019-20 to collect a preliminary data incidence level pattern prevalence stem rot disease. The district Warangal has highest rot. lowest found Telangana's Wanaparthy Nagarkurnool districts. Disease correlated with weather parameters, Kharif-2019, temperature, relative humidity rainfall showed positive correlation, whereas evaporation negative Rabi-2019-20, correlation correlation. This study provided elementary idea about per cent as well paved path for developing ecosystem specific management strategy reduce impact soil borne diseases different districts Telangana.
