Protect Wheat Yield From Rust Damage

Aproach® fungicide controls wheat rust damage to guard yield potential.

Wheat rust damage — a double threat to the crop — is often difficult to predict. Not only can rust overwinter from last season’s grass weeds or crop residue, but spores can travel hundreds of miles on the wind.

Some of the worst yield losses have occurred when spores blown from the South have infected late-developing, susceptible wheat crops in the Central Plains and Midwest.

Once infection occurs, leaf rust and stripe rust can move quickly to cause serious yield and grain quality loss. Kansas State University has observed yield losses in excess of 60 percent if rust infects wheat at the flag leaf stage without treatment. Fungicide applications that arrive too late can allow significant yield loss from rust damage, especially in combination with other diseases, such as Septoria leaf spot.

Rust spreads quickly as temperatures warm up to 59 to 72 F. Watch for reports of rust appearing in other areas, which could send infecting spores your way.

Delivering both residual activity and systemic movement within the plant, DuPont Aproach® fungicide helps preserve yield potential while offering treatment flexibility. DuPont field trials show improved plant health when Aproach® is applied at 3 to 4 ounces per acre during tillering. Aproach® may be a tank-mixed with a postemergence herbicide.

For fungal disease protection at the jointing/flag leaf stage, growers can apply 6.8 ounces per acre of DuPont
Aproach® Prima fungicide. Aproach® Prima starts with the same unique strobilurin as Aproach® and adds a triazole for additional control against fungal diseases such as powdery mildew, rust and leaf spot. Using two modes of action helps prevent development of fungicide-resistant diseases.

DuPont Aproach® and Aproach® Prima fungicide are not be available in all states. Contact your local DuPont sales representative for details and availability.
