Sulfonylurea Herbicides

The sulfonylurea family of herbicides is very broad.  SUs are used in many crops, including wheat, corn, and soybeans. 

Sulfonylureas are ALS-inhibitors. 

There are several weeds which have biotypes resistant to this family of herbicides but the most common one in our area is kochia.

Some common brand names of wheat herbicides include  Ally Extra, Express,  Finesse, Glean, Harmony Extra, Rave and the active ingredient in Ally, metsulfuron.
