A fast growing super weed that has destroyed soybean and cotton fields in southern states is popping up in Ohio alarming researchers and agriculture groups who fear its spread. It’s called “Palmer amaranth” and commonly used herbicides have no effect on this weed.

Infestations in Scioto County last year and in Fayette County this year have researchers in Indiana and Tennessee concerned as well as the Ohio Soybean Council. More than 3,000 soybean farmers and agriculture firms have been sent letters and DVDs to warn them of this invasive weed. It is very impossible to estimate the effect it could have on Ohio agriculture. OSU Extension Agent Mark Loux is asking farmers to send samples of suspect weeds to his office.
