The rice blast affects the leaves on which it causes diamond-shaped white to gray or reddish-brown lesions with reddish to brown borders. In this paper, authors have identified the rice blast caused by Pyricularia oryzae using five rice cultivars growing in Malwa region of Punjab and study the incidence and intensity of leaf, neck and panicle blast of rice. The surveillance was carried on tillering and around flowering stages. The highest leaf blast and incidence was 80.0%, 19.0% recorded, whereas the lowest was 21.0%, 14.0% observed. The rice blast shows the occurrence for the disease having the ideal predisposing conditions.
