Turcicum leaf blight of maize caused by the fungus Exserohilum turcicum is a serious foliar disease of maize distributed widely throughout the world and causing significant yield losses. The disease is more prevalent in humid weather with temperature between 20-280C and causes small cigar-shaped lesions to complete destruction of the foliage. Although, there are several management practices available, identification and deployment of host plant resistance is a pragmatic approach to control the disease. Further, TLB can be managed either through cultural/physical control, biological control, chemical protection or by introducing genetic resistance through plant breeding.
