Barrier? 50W

Barrier® 50W Dichlobenil Herbicide is formulated to stop all vegetative growth under asphalt when applied prior to paving. By eliminating vegetation beneath asphalt, Barrier 50W helps prevent blemishes and repairs associated with surface heaving, punctures, and sprouting weeds for several years, as long as the asphalt surface remains intact.

Barrier 50W controls annual and perennial grasses and broadleaf weeds, including chickweed, crabgrass, dandelion, foxtail, Poa annua, and many more as listed. And Barrier 50W poses minimum risk to ornamentals growing adjacent to the asphalt because any roots penetrating the treated area are pruned off, and the active ingredient is not picked up by the root system.


Barrier 50W:
  • • Stops all vegetative growth under asphalt when applied prior to paving
  • • Helps prevent plant growth damage to asphalt
  • • Controls listed annual and perennial grasses and broadleaf weeds
  • • Does not affect trees or woody ornamentals when applied as directed
