Palmer Amaranth has been found in multiple fields in Knox County, in Richland County (just north of the County line) and in Delaware County. IT’S HERE!!!
While we must remain vigilant to prevent more weed seeds from entering Knox County, we now must also focus on preventing the spread of this invasive and devastating weed.
Glyphosate-resistant waterhemp has also been found in Knox County! As harvest continues, “keep on the look-out” for these weeds. Harvest is a good time to evaluate the “weed bank” you have in each field. Don’t forget to check field borders and fence rows. Contact the Extension Office (740-397-0401) if you have any questions or if you come across a weed that you need help identifying. Remember, weed seeds are easily spread within a field and from field to field during harvest.
