Research shows corn fungicide application at tasseling pays off most often

As disease pressure ramps up across the Corn Belt, many growers are trying to determine the return on investment for fungicide.

Tyler Harp with Syngenta tells Brownfield research indicates an application when the corn plant is tasseling pays the most dividends.

“Our data shows that 8 out of 10 times, that’s going to be a profitable application regardless of the conditions that occur afterwards.”

He calls the first application foundational.

“That’s the one that’s going to preserve the most yield potential. That’s the one that’s probably going to protect you the most against diseases like tar spot or southern rust that may come in. That’s also one of the most important developmental stages in the crop to be protected.”

Harp says if conditions conducive to crop diseases continue, a second fungicide application could also be warranted.
