Since the first appearance of glyphosate resistant palmer amaranth and waterhemp in Adair County, each species has spread further throughout the county.

Feedstuffs, machinery, and wildlife all play a role in the spread of these weeds.



To make things even more difficult, some populations of waterhemp have also been found to be resistant to additional control options.

It is extremely important that these weeds are identified and controlled early. If left to grow, these weeds become uncontrollable and forfeiture of the crop is inevitable. Soybean fields that are found to have populations of these species this year should be rotated to corn next year to help provide more control options. Prior to these fields returning to soybeans, a management strategy for these weeds should be properly developed.

Effective pre-plant strategies will be essential for controlling these weeds.
