A roving survey was conducted during 2008–09 and 2009–10 of pigeonpea crop at various places of Varanasi and Mirzapur districts of Uttar Pradesh to know the status of Macrophomina stem canker (MSC). The MSC incidence recorded in the range of 1 to 60% in 2008–2009 and 0 to 19.5% in 2009–2010. The incidence during 2008–2009 was highest at Dhaurahara (60%) followed by Chilbilla (25%), Dugmugpur, Arjunpur and Basani (20%), Lalpurchatti (10.25%), Fulwaria (10%) and Sagarpur (9.5%). During 2008–09, hundred per cent disease prevailed in both the districts, while in 2009–10 crop season, the disease prevalence was 52.63% and 75% in Mirzapur and Varanasi district, respectively. Due to the more conducive weather conditions for disease development in 2008–09 crop season, the disease prevalence was so high.
