Over the past several years many have had concerns about scouring rush creeping into crop production areas. Scouring rush is not a typical agronomic weed.

Some of this can be determined by pulling some individual horseweed plants out of these fields and breaking the stem in half. If the stem is beginning to discolor or Continue reading
