Web1 de abr. de 2024 · Northern corn leaf blight (NCLB) is a globally devastating maize foliar disease caused by Setosphaeria turcica (Luttrell) Leonard and Suggs. Early intelligent diagnosis and warning is an effective and economical strategy to control this disease. Northern corn leaf blight (NCLB) or Turcicum leaf blight (TLB) is a foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria turcica. With its characteristic cigar-shaped lesions, this disease can cause significant yield loss in susceptible corn hybrids. Ver mais Lesions can eventually expand to a more oblong or “cigar” shape. They may also coalesce to form large areas of necrotic tissue. There are several host-specific forms of E. turcicum. The most … Ver mais The ideal environment for NCLB occurs during relatively cool, wet seasons.

If severe disease is present two to three weeks after silking in field corn, grain yields may be reduced by 40 to 70 percent. In the U.S. … Ver mais Spores of the fungus that causes this disease can be transported by wind long distances from infected fields. Spread within and between fields locally also relies on wind blown spores. E. turcicum causes disease and reduces yield in corn … Ver mais In nature, E. turcicum lives and reproduces in an asexual phase with a relatively simple life cycle. In temperate regions, the fungus overwinters mycelia, conidia, and chlamydospores in the infected corn debris. When conditions become favorable the … Ver mais Preventative management strategies can reduce economic losses from NCLB. Preventative management is especially important for fields at high risk for disease development. In-season disease management options, such as fungicides, are also available. Ver mais
