Prodoxaben is a granular preemergent herbicide that controls over 150 grassy and broadleaf weeds in established turfgrass, lawns and ornamentals. Prodaxaben’s active ingredient is a combination of Prodiamine (Barricade®), which controls grassy weeds like crabgrass and poa annua, and Isoxaben (Gallery®) which is effective on over 100 broadleaf weeds. Plus it can be applied on plants or turf, making it your go-to pre-emergent both spring and fall. It offers season-long preemergent control, so one application provides residual control for 3-8 months, depending on application rate and region, reducing labor and follow-up sprays.
