Chlorsulfuron is an active ingredient used in herbicides which control select broadleaf weeds and other undesirable grasses. Originally used for agricultural weed control and selective  control of weeds in wheat (pre- and/or post-emergent to crop) and barley as well as reduced tillage fallow preceding wheat, chlorsulfuron eventually was sold commercial to use to control broadleaf and grassy weeds on residential and commercials lawns and turf.

What is Chlorsulfuron?

Chlorsulfuron (Chemical name: 2-chloro-N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) aminocarbonyl]-benzenesulfonamide (58)) was the first commercial herbicide from the sulfonylurea group. It is 100 times more active than traditional herbicides so very low rates are used in the field.

It is a selective and translocated herbicide that can be absorbed through the leaves and roots of the targeted weed. Its main uses are for the control of a large variety of grass and broad-leaved weeds as pre-emergence application on wheat or as a postemergence application on wheat, barley and oat crops. 

Some of the key weeds chlorsulfuron is known to successfully control include:  Velvetleaf, pigweed, mustards, shepherd's purse, lambsquarters, Canada thistle, sunflower, henbit, plantain, smartweed, curly dock, Russian thistle, chickweed, cocklebur and many others. It has activity on most broadleaf weeds and some annual grass weeds. Certain perennials like Cirsium arvense are also sensitive to the effects of chlorsulfuron.

Wild oats, cheat and nightshade are tolerant of this material. Broadleaves are more susceptible than grasses.  Shallow incorporation may improve grass control but may also reduce broadleaf control.  It is known to be a slow killing herbicide yet is still very effective.

How Chlorsulfuron works

The mode of action of chlorsulfuron is that it stops cell division in plant roots and shoots, which in turn causes plants to not be able to grow any further.

How Safe Is Chlorsulfuron?


Chlorsulfuron has a low toxicity to mammals, birds and fish. Chlorsulfuron acts on the ALS enzyme in plants which is not present in animals and this is the main reason it is classified for its low toxicity. Chlorsulfuron presents a low hazard to the environment because it is used at low diluted rates and breaks down relatively quickly in most field situations and in the environment. Plants resistant to chlorsulfuron have developed and are expected after repeated use.


While it is a relatively safe chemical to use, it is still highly recommend to use protective equipment before applying. Gloves, protective glasses and long sleeve clothing should be a bare minimum level of protection. Please refer to the product label for specific safety instructions.
