Aproach Fungicide Has EPA Registration for Plant Disease Control

New option delivers reliable improvement in plant disease control and yield for corn, soybean, cereals, dry bean and canola growers

Wilmington, Delaware (January 2, 2013)--The U.S. Environmental Protection Agency (EPA) has granted registration approval for DuPont™ Aproach™ fungicide. Aproach™ will give corn, soybean and wheat growers enhanced protection from a broad spectrum of foliar and soil-borne diseases. The new fungicide will provide more reliable plant disease control and yield opportunities through both preventive and curative disease control, redistribution through the plant for more complete coverage, and rapid movement into and within the plant.


“Aproach™ has unique properties that will deliver results growers can see, from protection against production-limiting diseases to increased harvestable yield,” said John Chrosniak, regional director, North America, DuPont Crop Protection. “Aproach™ is another powerful tool from DuPont Crop Protection that will help growers address the challenge of producing high-quality crops to feed a growing world population.”

Within its class of fungicides, Aproach™ has unprecedented movement into and within the plant. This movement rapidly protects poorly covered leaf surfaces, plus leaves and stems that have not yet emerged, and delivers protection closer to the soil surface where many plant diseases originate.

Better coverage, preventive and curative activity, and residual control means Aproach™ helps compensate for less-than-ideal application timing, so growers are better able to defend yield despite challenging conditions.

Research has shown Aproach™ helps reduce incidence of yield-robbing diseases, including gray leaf spot, Northern corn leaf blight, Southern leaf blight and common rust in corn; soybean white mold, frogeye leaf spot, brown spot and Asian soybean rust in soybeans; and powdery mildew, rusts, tan spot, septoria leaf blotch and glume blotch in wheat.

• When applied to corn under stress, Aproach™ nearly doubled total leaf area and more than tripled average chlorophyll index compared to a leading fungicide.1 Increased green leaf area gives a corn plant greater opportunity to achieve its yield potential.

• In soybeans, Aproach™ demonstrated up to 85 percent reduction in white mold severity, 60 percent reduction in brown spot severity compared to leading fungicide programs and a yield increase of seven bushels per acre compared to the untreated plots.2

• In wheat, Aproach™ showed 62 percent uptake into leaf cells two days after application and 80 percent uptake seven days after application. Competitive fungicides achieved no more than 17 percent uptake by seven days after application.3

For added crop protection and efficiency, Aproach™ may be tank-mixed with a variety of herbicides and insecticides, including DuPont™ Harmony® Extra SG herbicide for broadleaf weed control in wheat, DuPont™ Asana® XL insecticide for control of aphids and beetles in soybeans and DuPont™ Prevathon® insect control for effective control of yield-reducing worms in corn.
