Prodiamine 65 WDG — Pre-Emergent Herbicide
Prodiamine 65 WDG is a pre-emergent herbicide from Quali-Pro built for season-long control of grassy and broadleaf weeds, with crabgrass and annual bluegrass (Poa annua) as standout targets. It’s labeled for use across turf, golf courses, landscapes, nurseries, and trees, and its flexible timing means it can go down in spring or fall depending on the weed pressure you’re managing.
A few things make it stand out as a pre-emergent option:
- Concentrated active ingredient: At 65% prodiamine, it can be applied at rates as low as a quarter of what some competing pre-emergents require, while still delivering season-long control.
- Stays where it’s needed: Low solubility and volatility keep the product anchored in the weed germination zone rather than moving or breaking down prematurely.
- Non-staining formula: Won’t discolor hardscapes, equipment, or turf surfaces during application.
- Tank-mix friendly: Works well alongside fertilizers and iron solutions, making it easy to fold into existing maintenance programs.
Beyond crabgrass and Poa annua, it’s also effective against henbit, knotweed, chickweed, spurge, foxtail, and goosegrass — covering most of the common pre-emergent targets turf and landscape managers deal with. It’s classified under WSSA Group 3 (mitotic inhibitor) and is comparable to Barricade 65 WG, often used as a more budget-friendly alternative with the same active ingredient profile.
