Recently there have been reports in states across the country indicating that Palmer amaranth has been found in fields seeded for pollinator habitat. Palmer amaranth is an aggressive weed that is on Ohio’s noxious weed and prohibitive noxious seed list.
The Ohio Department of Agriculture is looking into the issue, according to Matthew Beal, ODA division of plant health. None of the reports about the weed being found in pollinator habitat seed mixes have come from Ohio. Weed seed can be spread in a variety of ways—including by air, animals, rain, soil and mechanical means, according to the American Seed Trade Association.
The association urges farmers who have identified Palmer amaranth in fields or conservation plantings to contact their seed supplier, local Natural Resource Conservation Service, Farm Service Agency or Extension professional.
