Generic herbicides in lettuce
By Barry Tickes, UA Area Agriculture Agent
A proprietary use patent is granted for 17 years to the company that first develops a herbicide. All of the active ingredients in the herbicides commonly used on vegetables are now off patent. Most have been off patent for more than 20 years.
Some companies have developed proprietary formulations that contain off patent active ingredients. Examples include Prowl H2O, GoalTender, Select Max and Dacthal Flowable.
