Northern corn leaf blight (NCLB) or Turcicum leaf blight (TLB) is a foliar disease of corn 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.
The Western corn rootworm, Diabrotica virgifera virgifera, is one of the most devastating corn rootworm species in North America, especially in the midwestern corn-growing areas such as Iowa. A related species, the Northern corn rootworm, D. barberi , co-inhabits in much of the range and is fairly similar in biology.
Diabrotica undecimpunctata, the spotted cucumber beetle or southern corn rootworm, is a species of cucumber beetle that is native to North America. The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle.
For example, the northern corn rootworm (Diabrotica barberi) became adapted to a corn-soybean crop rotation by spending the year when the field is planted with soybeans in a diapause. [107] As of 2014, few new weed killers are near commercialization, and none with a novel, resistance-free mode of action. [108]

The toothed flea beetle, adult 12-spotted cucumber beetle, seed corn maggot, wheat wireworm, white grubs, and larvae of corn rootworms can also carry P. stewartii from one plant to another during the summer. These pests cannot overwinter and transmit this disease. [13] All sweet corn varieties are susceptible to wilt in the first leaf stage.
