Ohio State Publishes Free Weed Resistance Resource Site

Ohio State University Extension is currently in the second year of a three-year partnership of ag industry, United Soybean Board, and a number of land grant universities to provide education and resources for managing herbicide site of action and mitigating herbicide resistance. This is resulting in some additional free publications for use by agronomists, growers, CCA’s, etc.


Examples can be found on http://agcrops.osu.edu/specialists/weeds, either in the “News of Interest” or the “Herbicide Resistance Information” sections.

Brief Overview Of Content Resources Offered:

  • “Herbicide Classification Chart,” “Take Action” and “Know Your Weeds” are single page/posters. They are available in roughly a 20×30 size (glossy paper), although some foam core posters about twice this large were made. The smaller size is suitable for distributing to clientele, while the larger would be suitable for the wall of a business or office.
  • “Control of Marestail in No-till Soybeans” was expanded to four pages so that it provides more comprehensive information. It can be downloaded and printed as needed.
  • “Weed Control Guide for Ohio and Indiana” can be downloaded free as a pdf from OSU or Purdue weed science websites.
  • A “Palmer amaranth video” provides an overview of the biology of this weed and the problems that it has caused in the South. It can be viewed online via http://agcrops.osu.edu/specialists/weeds. This was also mailed out to ag industry and CCA’s on a DVD.
