A plant pathologist says the application timing of fungicides is key when managing Fusarium Head Blight in winter wheat.

Nathan Kleczewski with the University of Illinois tells Brownfield, farmers have been asking if earlier application can make a difference, but his research suggests fungicide application at flowering is best.

“You can get a reduction in head blight if you go out when the heads are just starting to pop, but it’s not nearly as efficacious as if you got out at a recommended time which is flowering to 5 or 6 days after flowering.”

He says their research also shows there are no significant benefits to using a high rate of fungicide to suppress head blight.
