Product Overview

Barricade 4FL Herbicide - Control Weeds Before They Germinate

Prevent weeds season long with a single application. Barricade® 4FL herbicide controls susceptible weeds by preventing growth and development of newly germinated weeds.  All applications must be made before the targeted weeds germinate; Barricade 4FL will not control weeds after they have already emerged.


  • FOR SUMMER ANNUALS: For annuals such as crabgrass, foxtails, goosegrass and barnyardgrass, a single application can be made as early as January to prevent weeds all season long. Also, late fall applications of Barricade 4FL in cool-season turf grasses after soil temperatures fall below 50°F but before the ground freezes will control crabgrass the next spring.
  • FOR WINTER ANNUALS: For annuals like Poa annua, henbit and chickweed, applications should be made in the summer/fall before these broadleaf weeds germinate. For control of Poa annua, apply Barricade 4FL in August/September to non-overseeded turf before Poa annua seeds germinate.

Barricade 4FL also offers programmable weed control; adjust application rate to dial in the length of weed control you need.  Use higher rates for maximum residual and length of control, use lower rates in shorter growing seasons.  See label for additional details. Length of control also varies by turf species and application time of year.

Barricade 4FL is labeled for a wide range of turf species, use sites and weeds controlled.  It can be used on residential turf, golf courses (except putting greens), sod farms and nurseries.  It is also labeled for container, field grown, and landscape ornamental plantings including christmas tree farms.  More than 30 turf weeds are on the label; controlling summer annuals when applied pre-emergently in the spring and winter annuals when applied in the summer/fall.
