Serene is a liquid herbicide for non-selective vegetation control of areas in and around established trees and shrubs, non-crop areas, right-of way, industrial land sites and in and around labelled food crops. Leaves no harmful residue in the soil.

GENERAL DIRECTIONS FOR USE
Best results are achieved from spring and early summer applications to actively growing young weeds. Degree of control depends on several factors, including weed size and stage at application. Apply on a mostly sunny day with temperatures at or above 21° C (70° F). Small annual weeds may be completely controlled with a single application. Control of larger, more established weeds, not completely desiccated with one application, may be short-term and require retreatment. Weeds that are mature, dormant or hardened due to moisture stress tend to be more tolerant to herbicide treatment. Complete coverage of undesirable vegetation is necessary to achieve control. Only contacted vegetation will be affected. Seedling perennial weeds may be controlled with a single application; however, repeat application is required for control of regrowth of established perennial weeds. Rainfall within 1 hour of application will reduce degree of control. DO NOT re-enter or allow entry into the treated areas until the residues have dried. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
