Barricade 4FL Herbicide
Selective Pre-Emergence Control of Grass and Broadleaf Weeds
Barricade® 4FL herbicide controls susceptible weeds by preventing growth and development of newly germinated weeds. Barricade 4FL is labeled to control more than 30 weeds, and is guaranteed to provide long-lasting, preemergent weed control with one application. All applications must be made before the targeted weeds germinate; Barricade 4FL will not control weeds after they have already emerged.

Instructions:
In many areas a single application of 21-48 ozs./A of Barricade 4FL will control goosegrass. However, under heavy goosegrass pressure and/or an extended growing season, weed control will be most effective by making an initial application of 21-26 ozs./A followed by a second application 60-90 days later. Note: Do not exceed the maximum rate for the turf species listed in the Maximum Application Rates Table.
