Anthracnose mung caused Colletotrichum lindemuthianum Rhizoctonia solani, respectively. Their occurrence development highly influenced weather conditions during the cropping season. Based on epidemiological data recorded at Pantnagar for two consecutive years (2019 2020), disease predictive models were developed using stepwise multiple regression. The result from revealed that rainfall, T(min), rainy days, morning relative humidity statistically significant. Whereas, T(max), evening humidity, bright sunshine hours non-significant. Significant parameters employed to develop suitable prediction commonly grown varieties bean. further validated incidence collected 2021. root mean square error values varied between 0.0002 – 0.0011, shows accurate acceptable.
