Do you have Wild Proso Millet on your farm?
Late summer is a good time to identify grassy weeds because they often have seed heads. Wild proso millet is present in NY and can be a problem weed in sweet corn and other vegetable crops. Wild proso millet is a large tufted annual grass with erect stems branching from the base. It may grow up to 2 m tall and is often nearly as tall as sweet corn.
