EPA Clears DuPont Aproach Fungicide

Posted by |19 December 2012

DuPont said it received U.S. Environmental Protection Agency registration approval for its Aproach™ fungicide, which will give corn, soybean and wheat growers more protection from a broad spectrum of foliar and soil-borne diseases.

Within its class of fungicides, Aproach has unprecedented movement into and within the plant, DuPont said. 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.

“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.

According to DuPont, 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. Increased green leaf area gives a corn plant greater opportunity to achieve its yield potential.
In soybeans, Aproach demonstrated up to 85% reduction in white mold severity, 60% reduction in brown spot severity compared to leading fungicide programs and a yield increase of seven bushels per acre compared to the untreated plots.
In wheat, Aproach showed 62% uptake into leaf cells two days after application and 80% uptake seven days after application. Competitive fungicides achieved no more than 17% uptake by seven days after application.
