Semera SC Herbicide gallon (128 oz)

Semera SC Herbicide is a professional suspension concentrate herbicide formulated with 41.4% flumioxazin, delivering 4 pounds of active ingredient per gallon for fast contact activity and long-lasting residual control. As a Group 14 PPO inhibitor, Semera SC provides pre-emergent and post-emergent control of a wide range of broadleaf weeds, grasses, and aquatic vegetation in non-crop areas, forestry sites, ornamental landscapes, dormant bermudagrass, and aquatic environments.

Semera SC is an excellent choice for bareground vegetation management, industrial sites, rights-of-way, railroads, airports, reforestation projects, landscape ornamentals, and aquatic weed control. It controls many difficult species including kochia, pigweed, Russian thistle, annual bluegrass, crabgrass, goosegrass, duckweed, watermeal, hydrilla, coontail, pondweed, and filamentous algae. The suspension concentrate formulation offers convenient measuring, mixing, and application while providing the same proven flumioxazin chemistry trusted by professional applicators.

Application Notes

For terrestrial applications, apply 8 to 12 fl oz per acre before weed emergence for residual control or after emergence for post-emergent activity. For best post-emergent results, apply to actively growing weeds less than 2 inches tall and include a labeled non-ionic surfactant.

For aquatic surface applications, apply 6 to 12 fl oz per surface acre plus an aquatic-approved adjuvant. For subsurface applications, apply rates sufficient to establish 200 to 400 ppb flumioxazin concentration in the water column. Aquatic applications perform best when made early in the morning and in water with a pH below 8.5.

Semera SC is rainfast within one hour after application. Do not apply to actively growing turfgrass, golf course putting greens, or desirable plant foliage.
