How do you control northern corn leaf blight?
Resistant hybrids, crop rotation, and fungicides are ways to do it. Cool and wet conditions in recent years have set lots of cornfields up for northern corn leaf blight (NCLB). Large elliptical-shaped lesions on corn leaves herald this fungal disease.
Which is a suggestion for managing Northern leaf blight?
A combination of rotating away from corn for one year followed by tillage is recommended to prevent the development of NCLB. Rotating to a non-host crop can reduce disease levels by allowing the corn debris on which the fungus survives to decompose before corn is planted again.
How do you treat corn blight?
Treating northern corn leaf blight involves using fungicides. For most home gardeners this step isn't needed, but if you have a bad infection, you may want to try this chemical treatment. The infection usually begins around the time of silking, and this is when the fungicide should be applied.
What causes northern corn leaf blight?
Northern corn leaf blight (NCLB) 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.
What type of leaf does corn have?
The corn leaf plant, more commonly known as corn plant (Dracaena fragrans), is a broadleaf evergreen that may grow up to 50 feet tall within its native range in the tropics of western Africa, though it is more commonly seen as an indoor houseplant with a height between 4 to 6 feet.
Can corn blight?
Northern corn leaf blight (NCLB), caused by the fungus Exserohilum turcicum, is an increasingly important disease in the U.S. Corn Belt. ... NCLB can cause yield loss if it develops before or during the tasseling and silking phases of corn development.
What causes GREY leaf spot?
Gray leaf spot disease is caused by the fungus Pyricularia grisea, also referred to as Magnaporthe grisea. The frequent warm rainy periods common in Florida create favorable conditions for this fungal disease. This fungus slows grow-in, thins established stands and can kill large areas of St.

What is corn rust?
Common rust is caused by the fungus Puccinia sorghi and occurs every growing season. It is seldom a concern in hybrid corn. Rust pustules usually first appear in late June. Early symptoms of common rust are chlorotic flecks on the leaf surface.
How do you prevent corn blight?
Try resistant varieties. Leaves that dry rapidly after rain or heavy dew are unlikely to develop problems with leaf blight, so grow corn at proper spacing to make sure sunlight reaches all the leaves. Avoid places near trees, fences, or low pockets where dew is heavy and slow to dry.
Where do the symptoms of soybean rust first appear?
Symptoms. Symptoms begin on leaves in the lower plant canopy. Tan or reddish-brown lesions (spots) develop first on the underside of leaves.
