Brown spot disease (Bipolarisoryzae) is increasing threat to global food security in the world as well as the most damaging disease of rice crop in Pakistan. In September 2017, a field survey was conducted in four rice-growing districts of Punjab namely (Faisalabad, Hafizabad, Sheikhupura and Lahore) and diseased samples were collected from different fields of rice showing disease symptoms. The results showed that Ninety-seven fields of rice were surveyed and 62 were found infected with disease.Disease prevalence was highest in district Sheikhupura 84%, followed by Lahore, Hafizabadand Faisalabadwith 80%, 60% and 53% respectively. The risk of disease incidence was highest in district Sheikhupura and Lahore82% in Super Basmati, 74% in KSK-282 followed by Faisalabad and Hafizabad71% in Super basmati, 60% in Super rice respectively. The severity rate was the highest in district Lahore at KotPindiDass 88%in Super rice, but the minimum wasobserved atShamke road 46% in PK 386. It is concluded that, the disease incidence and severity level of B. oryzae was higher in fields of district Sheikhupura in Punjab, Pakistan.
