Powdery Mildew Could Limit Yield Potential in Wheat

Aproach® fungicide controls powdery mildew to guard yield potential in wheat.

Start scouting for signs of powdery mildew in wheat as spring air temperatures increase. Snow cover, crop residue and cool weather can provide an environment that allows overwintering fungus to spread quickly once temperatures warm to 60 F to 75 F. Early signs of powdery mildew can be easy to miss, because they first appear on lower leaves.

Look for patches of whitish-gray cottony growth on leaf surfaces. The disease can spread to upper leaves rapidly, limiting yield. Powdery mildew is favored by susceptible high-yielding varieties, dense foliage and high nitrogen levels.

Using 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 foliar health when Aproach® is applied at 3 to 4 ounces per acre during tillering. Aproach® may be tank-mixed with a postemergence herbicide, such as DuPontHarmony® Extra SG

Later in the season, for disease protection at the jointing/flag leaf stage, growers can apply DuPont Aproach® Prima fungicide at 6.8 ounces per acre. It starts with the same unique strobilurin in Aproach® and adds a triazole for additional control of 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 fungicides are not be available in all states. Contact your local DuPont sales representative for details and availability.
