This herbicide inhibits the enzyme acetolactate synthase in plants (ALS inhibitor). Spinnaker can be used either pre- or post-emergence of the weeds. When the product is applied pre-emergence of the weeds, susceptible weeds may emerge but growth will be retarded and the weeds will either die or remain stunted and will not compete with the crop. Adequate soil moisture is important for optimum activity. When applied post-emergence of the weeds, they will either die or remain stunted and will not compete with the crop. For use post-emergence of the weeds, a non-ionic surfactant must be added to Spinnaker.
