We have been screening a random sample of waterhemp populations for herbicide resistance over the past two years. Herbicides used in the screen include mesotrione, atrazine, 2,4-D, fomesafen, and metolachlor.

Results of our research show that it’s possible for Ohio waterhemp populations to have some level of resistance to one, several, or all of these herbicides. Glyphosate is not included because we assume almost all populations are already resistant to this. We are also part of a regional project that has been screening for dicamba and glufosinate resistance with populations that we supply, although none has been identified to date. Our sample size has been small so far, so at this point we are looking to expand our screening to include waterhemp populations submitted by anyone in Ohio looking for more information about their response to herb

With the crappy spring we missed proper burndown timing, pre-emergent herbicide application, and now are working on missing the proper timing for post applications. In 2020 we lost the soybean dicamba products after June 30, and now that is permanent with the new labels. In most years and most scenarios we should be done with soybean spraying by July 1, right.
The Ohio, Indiana & Illinois Weed Control Guide is a great resource for getting management tips on how best to apply herbicides. See the recommendation tables to choose products for these post applications. The Guide is available from our now reopened county Extension offices, or look for more information on-line from Mark Loux on his Weed Management website: https://u.osu.edu/osuweeds/.
