Barricade 250ml Herbicide

Barricade Turf Herbicide

Barricade is a trusted pre-emergent herbicide that creates a protective barrier in the soil to stop a wide range of grassy weeds before they emerge — including the troublesome Poa annua (Winter Grass).

With just one application, Barricade provides up to six months of weed control, giving you flexibility in timing and long-lasting results. Applications can be made well ahead of germination, ensuring your turf is protected right through the season.

Unlike some herbicides, Barricade stays high in the soil profile, meaning turf roots grow safely beneath the barrier. This keeps your lawn in excellent condition while keeping weeds at bay.
