For Sunflower Weed Control Use DuPont™ ExpressSun® Herbicide

ExpressSun for broad-spectrum weed control in sunflowers

Weed control in sunflowers, especially broadleaf weed control, has always been difficult. In all other crops, sunflowers are considered a weed and are easily controlled by a wide range of herbicides. That means new technology was needed to help sunflower growers maximize yield potential through clean fields.

DuPont and Pioneer have partnered up to bring an exciting new system to sunflower growers in Western Canada. Pioneer® brand sunflower hybrids with the DuPont™ ExpressSun® herbicide tolerant trait are tolerant to DuPont™ Express® SG herbicide.

This unique system is designed to maximize weed control in sunflower crops, enhancing ease of production and yield. It provides improved weed control over conventional hybrids with traditional herbicides and gives growers a cost-effective option for broad-spectrum weed control.

Herbicide-tolerant sunflower hybrids

With tolerance to DuPont™ Express® SG herbicide, this revolutionary production system offers:

  • Broad-spectrum control or suppression of broadleaf weeds
  • A simplified approach to weed control in sunflowers
  • Improved yield potential through enhanced weed control
  • A cost-effective crop management solution
  • Complete re-cropping flexibility the following year

Developed through traditional plant breeding methods

Pioneer and DuPont researchers brought this tolerance trait to market and developed this hybrid through traditional methods of plant breeding without the use of genetic modification. Sunflowers with the DuPont™ ExpressSun® trait will be grown, harvested and used just like any traditional sunflower seed.

Pioneer® brand P63ME70 and Pioneer® brand P63ME80 are the hybrids with the DuPont™ ExpressSun® trait for tolerance to Express® SG herbicide:

  • Strong performance package
  • Excellent yield potential
  • Exceptional standability
  • Above-average emergence
  • Strong root and stalk strength
  • High oil content
