Wheat crop is cultivated as a staple food in Pakistan covering the largest area than any other cereal crop and contributes 60% of the daily dietary diet. Significant yield losses are reported due to different biotic and abiotic stresses in southern Punjab. Karnal bunt (Tilletia indica) is a quarantine importance disease becoming the challenge that deteriorates its quality and ultimately unacceptable for human consumption and export. The current study was designed to conduct the karnal bunt survey in six high yielding districts of South Punjab i.e. Bahawalpur, Muzaffar garh, Khanewal, Vehari, Lodhran and Rahimyar Khan during three consecutive wheat cropping seasons 2014-17. Maximum seed production will be obtained from these districts for next crop seasons. Two hundred and sixteen samples were collected during the survey from one hundred and twenty one wheat grains heaps from sixteen tehsils of six districts. Maximum disease incidence (3.24%), (1.38%) and (1.4%) was observed in village Januwala of district Bahawalpur (2014-15), in Dahanot of district Lodhran (2015-16) and in Derawar Fort of district Bahawalpur (2016-17) respectively. Over all the intensity of the disease is very low in southern Punjab which is a good sign. Regular monitoring of the disease to identify the Karnal bunt free areas by conducting extensive surveys should be encouraged in other areas of wheat also.
