Studies on variability of Exserohilum turcicum causing Northern corn leaf blight

Abstract

Maize is considered as one of the most important staple food crops in the world. This crop has been taken into cultivation after the difficulty and interrelated relationship development; hence these crops have the most established record of cultivation by humanity. In current scenario maize cultivation is facing many challenges by several biotic and abiotic factors. Among all diseases, Northern corn leaf blight (NCLB) caused by Exserohilum turcicum (Passerini) (Leonard and Suggs.) accounts for significant damage to this crop and ultimately responsible for maximum loss in terms of quality and quantity. Disease symptoms first appear on the leaves at any stage of plant growth, but usually at or after anthesis. newline
