North Central Region Herbicide-Drift Risk Management Working Group

Project Director: Douglas Doohan, The Ohio State University

Locally produced vegetables, fruits and wines, and certified organic products (specialty crops) are amongst the fastest growing sectors of U.S. agriculture. Yet the continued growth and stability of these enterprises is threatened by droplet and vapor drift from rapidly expanding use of highly phytotoxic herbicides, specifically dicamba and 2,4-D. In the North Central region, speciality crops are at an extremely high risk of drift damage, due to their close proximity to herbicide-tolerant corn and soybeans. There is a need within the region on behalf of both speciality crop growers and commercial grain farmers for education opportunities and resource creation to better understand drift and how to prevent it. 

The goals of this group will be to evaluate and prioritize the many issues involved, and develop and disseminate new resources that meet the established priorities. Long term goals will be to help farmers recognize and respond to dicamba and 2,4-D drift risk. In order to address the many stakeholders affected by this problem, the group will consist of weed, agronomic, and horticulture crop specialists.


The North Central IPM Center granted a second year of funding for the Herbicide-Drift Risk Special Project. 

Additional Work to Come

  1. Weed or crop specialists are welcome to join.
  2. A fifth fact sheet will summarize research on comparative plant sensitivities to dicamba and 2,4-D. This is still in development and should be available this winter. 
  3. Slides for winter meetings are also being developed.
