Since the disease survives on infected residue, management practices … 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. Periods of wetness that last more than six hours at temperatures between 18 and 27 °C (64 and 81 °F) … Ver mais NCLB can cause significant yield loss in corn. 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. Corn Belt and Ontario, NCLB has recently become a significant disease, causing … Ver mais In nature, E. turcicum lives and reproduces in an asexual phase with a relatively simple life cycle.

Northern Corn Leaf Blight (NCLB) – Agriculture Monthly

WebNorthern corn leaf blight (NCLB) is a disease of corn caused by the fungus, Exserohilum turcicum. Severe outbreaks of the disease can cause up to 30-50% yield loss in dent corn if the disease is established before tassel [1]. NCLB also causes significant reduction in quality in sweet corn and silage corn.
