Abstract

Green gram is attacked by various fungal diseases out of which anthracnose incited by Colletotrichum truncatum is predominant in Arid Ecosystem of Rajasthan, India. Occurrence and development of anthracnose disease is significantly affected by epidemiological conditions during the cropping period.

Epidemiological data collected from ARS, SKRAU, Bikaner for two consecutive years (2023 and 2024) from which disease predictive model was developed for susceptible varieties through stepwise multiple regression.

The results revealed that Tmax, morning and evening relative humidity were statistically significant. Whereas, the Tmin and rainfall (RF) were statistically non-significant. Weather parameters showed significantly correlated with PDI were used to develop suitable anthracnose disease prediction model for susceptible varieties (on pooled basis) of green gram.
