Glean weed killer

The DuPont Company has commercialized two of these compounds. The first of these is chlorsulfuron (Fig. 1), formerly DPX-W4189, the active ingredient in Glean weed killer. It is being marketed by DuPont for use in small grains such as wheat and barley. 

Chlorsulfuron is the active ingredient in Du Pont Glean Weed Killer. A very important feature of this new selective herbicide compound is its very high herbicidal activity at very low application rates. The compound controls most broad-leaved weeds in small grains at 10-40 g/ha. It is nonvolatile and is active due to uptake through both foliage and root system.
