Researchers seek solutions as diseases grow tolerant to fungicide

All of the fungicides are sprayed preventively, not in response to what is seen in a field, Langston says.



Grower Greg Leger, owner and president of Leger & Son in Cordele, Ga., is grateful for the work researchers like Langston have done.

“Every time it rained, [gummy stem blight] would eat us up,” he says.

But that has changed since researchers have recommended effective mixtures and combinations of sprays.

“Now when we spray, we feel confident that we can keep it in check,” he said. “Gummy stem blight is not one of our major issues right now.”

Leger asks those who grow under his label to use Bravo before the fruit matures. Inspire Super and a combination of Topsin and Penncozeb are some of the other fungicides he uses.

“You have to stay on a spray program,” he says, “especially in rainy weather.”
