An invasive species is threatening Iowa soybean fields.
The Palmer Amaranth weed has now been found in five Iowa counties. The herbicide-resistant weed is especially troublesome in soybean fields.
The weed can be killed if it is found early. But if it is allowed to grow, no herbicide will stop it.
It can cut a field’s soybean yield by as much as 30-percent. That could mean millions in lost profits.
The Iowa Soybean Association is reminding farmers to be on the lookout for the weed and seek help if they spot it.
