All registered uses of cyanazine, the active ingredient in Bladex, ended in 2002. Although cyanazine had some limitations, it was an important sweet corn herbicide because 1) it provided good preemergence broadleaf weed control, 2) it degraded soon enough in the soil that other rotational crops could be planted after sweet corn harvest, and 3) it provided an alternative to atrazine in prohibition areas. Without Bladex, sweet corn growers and field managers may wonder what options currently exist for weed management in sweet corn and what the prospects are for the future.
