Disease Affecting Corn Crop in Seminole County

Corn farmers are about to see their hard work pay off.

"Corn is tassling and silking now."

But before that, they have a major problem to take care of...a disease known as Northern Corn Leaf Blight

"It can cause a yield loss, that's the problem. You get enough lesions on those leaves and you can have yield loss," Rome Ethredge said. Ethredge is the Seminole County Extension Agent.

Farmers have to face this disease annually, but this year is different.

"We're worried because it came in very early this year," Ethredge said.

"There's a chance that this disease could be very very severe given the type of weather that we've had and the type of management that we've got, if we do not control it early," Dewey Lee said. Lee is a professor at the University of Georgia and is a Corn Agronomist.

And just how does this affect the corn crop?

"You block out the ability of the plant to make the photosenthate or sugars to produce a good ear."

Extension agents also have suggestions for combating this disease.

"We suggest a good fungicide," Ethredge said. "Use it with at least two ingredients of that fungicide for short term and long term control of plant disease."

But this isn't just a Georgia problem.

"Corn growers in southeast Alabama and in the panhandle of Florida should be very concerned about it," Lee said.

If you are facing this problem, both Ethredge and Lee hope you keep an ear out to prevent this from affecting you.
