The DuPont Aproach fungicide, which will give corn, soy and wheat growers enhanced protection from a broad spectrum of foliar and soil-borne diseases, was granted registration approval by the Environmental Protection Agency (EPA).
The new fungicide will provide more reliable plant health and disease control performance 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. "It 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."
Aproach quickly moves into the plant, and it 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 grey-leaf spot, Northern corn leaf blight, Southern leaf blight and common rust in corn; soy white mould, frogeye leaf spot, brown spot and Asian soy rust in soy; and powdery mildew, rusts, tan spot, septoria leaf blotch and glume blotch in wheat.
When applied to corn under stress, it 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 soy, Aproach demonstrated up to 85% reduction in white mould severity, 60% reduction in brown spot severity compared to leading fungicide programmes and a yield increase of seven bushels per acre compared to untreated plots.
Aproach may be tank-mixed with a variety of herbicides and insecticides, including DuPontPrevathon insect control for effective control of yield-reducing worms in corn, DuPont Asana XL insecticide for control of aphids and beetles in soy, and DuPont Harmony Extra SG herbicide for broadleaf weed control in wheat.
