Pennant Magnum Herbicide 5L

Pre-Emergent Protection: Pennant Magnum Herbicide

Pennant Magnum Herbicide is a powerful, selective, pre-emergent solution designed to provide superior control of annual grasses, broadleaf weeds, and Yellow Nutsedge in warm-season turfgrass and various ornamental plantings. This professional-grade emulsifiable concentrate (EC) offers exceptional flexibility and a high degree of plant safety, making it a valuable tool for turf managers, landscapers, and nursery professionals.

The active ingredient, S-metolachlor (83.7%), belongs to the Group 15 family of herbicides (VLCFA inhibitors). It works by being absorbed by the weed’s emerging shoots, inhibiting cell division and growth shortly after germination. This unique mode of action ensures that it does not significantly inhibit new root development in established turfgrass, a crucial benefit for recovering turf or during sod production.

Pennant Magnum Herbicide is highly effective against challenging weeds like Yellow Nutsedge, Large and Smooth Crabgrass, Goosegrass, Doveweed, and Foxtails. A single application provides reliable, long-lasting residual control for up to 90 days, drastically reducing weed competition during the critical early growth stages of your turf or ornamentals.

It is labelled for use on a wide range of sites, including:

• Warm-Season Turfgrasses (Bermudagrass, Zoysiagrass, St. Augustinegrass, Centipedegrass)

• Nurseries (field-grown and container-grown ornamentals)

• Landscape Plantings

• Non-Crop Areas (golf courses, sports fields, cemeteries, etc.)

Its liquid formulation mixes easily with water or liquid fertilizer and can be sprayed directly over-the-top of many ornamental plants, offering unique application flexibility. Choose Pennant Magnum Herbicide for dependable, long-term, and safe pre-emergent weed control.
