First report of foliar blight of Convolvulus arvensis from Pakistan

A severe foliar blight disease was observed on wheat (Triticum aestivum L.) cultivars namely Morocco, Sehar-2006 and Inqilab-91 during March 2014 at Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad, Pakistan. During the same season, disease symptoms similar to wheat were also observed on field bindweed (Convolvulus arvensis L.) under field conditions. Pathogen was isolated from infected leaves of both field bindweed and wheat. Morphological and pathogenecity tests were conducted which confirmed the presence of Alternaria triticina the cause of foliar blight of C. arvensis. To the best of our knowledge, this is the first report of A. triticina infecting C. arvensis in Pakistan.
