Sunflower Pathologists Protect Sunflower Yields

Up to 90% of the 1.7 million acres of sunflowers planted annually in the U.S. are planted in the North Central region, where diseases pose a major threat to yield. Unfortunately, there has historically been a shortage of specialists and resources focused on sunflower health.

Formed in 2013 with funding from the USDA NIFA’s Crop Protection and Pest Management Program, the Sunflower Pathology Working Group connects experts from the U.S. and abroad to help farmers better manage diseases, insects and weeds. The group partners with universities, nonprofits, industry and government to extend outreach and multiply impact. The return on investment from awarded funds is nearly 14:1.

Impact and Reach

Collaborative efforts have:

  • Improved diagnosis of sunflower diseases
  • Facilitated informed treatment decisions
  • Informed decisions protect yield

Public Value

Sunflower products – oil, seed, butter, cut flowers and feed – support family farms, rural economies and public health. U.S. sunflower profits have ranged from approximately $225M to $760M in the past decade (based on USDA NASS data, 2015-2024).
