Effect of Northern Leaf Blight (Exserohilum Turcicum.
Turcicum leaf blight caused Exserohilum turcicum (Pass) K.J. Leonard and E.G. Suggs (Teliomorph: Setosphaeria turcica (Luttrell) Leonard and Suggs) is an old disease of sorghum and maize (Agrios 1997; Ramathani et al., 2011). Under many tropical conditions and especially on susceptible genotypes, considerable grain and fodder yield losses of up.

A total of nineteen isolates of Exserohilum turcicum were classified into races using the Ht gene bearing maize differential inbred lines. Three isolates were race 0, three were race 1, one was race 2, one was race 3, two isolates were race 12, and eight did not fit in the known classification. These were named and grouped as k1, k2 and k3.
Exserohilum turcicum is the causal agent of NLB of maize and sorghum (Agrios, 2005). Host specificity of E. turcicum has been observed in isolates from maize, sorghum and Johnson grass (Bhowmik.
Exserohilum turcicum and Puccinia sorghi cause foliar fungal diseases that affect maize crop in Argentina. These diseases, northern leaf blight and com- mon rust respectively, are presented each year with different levels of severity affecting significantly the yield in susceptible hybrids.
