Evaluation of race population distribution, fungicide sensitivity, and fungicide control of Exserohilum turcicum, the causal agent of northern leaf blight of corn
Northern leaf blight (NLB) of corn, caused by Exserohilum turcicum, is a yield reducing foliar disease common across the north central U.S. Previous race population distribution studies identified five physiological races present in the U.S., prior to 1995. For this study, 156 E. turcicum isolates …

Effect of Resistance Type on the Development of and Yield Losses Due to Northern Corn Leaf Blight
… effect of resistant type on the development of northern leaf blight (NLB), caused by Exserohilum turcicum, was studied on three dent corn (Zea mays L.) hybrids: A619 x A632, B73 x Oh545 and Mo17 x B73. Two nearly isogenic versions of each hybrid were used, one version carrying the resistance …

The Relative Efficiency of Replicates in Sweet Corn Hybrid Disease Nurseries and Posterior Probabilities as a Measure of Confidence in Assigning Sweet Corn Hybrids to Disease Reaction Categories
… or multiple trials. For each of three diseases (northern leaf blight, Stewart's wilt, and common rust), 1,000 simulated mean ratings each for 2,365 to 3,527 hybrids were produced as a random draw of two or three replicates. Boundaries for disease reaction categories from resistant (1) to …

The Genetic Architecture Of Quantitative Disease Resistance In Maize
… disease of maize (Zea mays L. ssp. mays), northern leaf blight (NLB, caused by Setosphaeria turcica L. anamorph Exserohilum turcicum). The maize nested association mapping (NAM) population, a reference design population consisting of 4,630 recombinant inbred lines, was evaluated over three …

Qualitative Resistance to Exserohilum Turcicum Race 2 in Maize (Corn, Genetics)
The fungus Exserohilum turcicum causes northern leaf blight of maize (Zea mays L.) and it is found in most maize growing areas of the world. This disease has been controlled effectively for over 15 years by qualitative and quantitative resistance. In 1979 a new race of the fungus (race 2) was found …

Interactions between oxidative stresses in corn
… sorghi), brown spot (Physoderma maydis), northern leaf blight (Exserohilum turcicum), and gray leaf spot (Cercospora zeae-maydis). Within a growing season disease severity was highly genotype-dependent; however, there were modest genotype-independent ozone effects, mostly significant under …

From field to rumen: foliar fungicide application on corn and its effects on the corn plant, corn silage, and Holstein cow performance
… Evaluators at R1 and R3 reported signs of Gray Leaf Spot and Northern Leaf Blight on the foliage. In part one, 24 individual corn plants from each treatment were collected R1 and R3 for weight and length measurement. At each collection, treatment corn plants were disassembled into leaves, …
