QualiPro Oxadiazon 2G Herbicide


Product Description:
QualiPro Oxadiazon 2G is a granular pre-emergent herbicide formulated to control a broad spectrum of annual grassy and broadleaf weeds in turfgrass, ornamental landscapes, and non-crop areas. The active ingredient, Oxadiazon (2%), forms a protective barrier on the soil surface to inhibit weed seed germination and establishment. It is a highly effective tool for professionals managing weed control in golf courses, sod farms, and residential or commercial landscapes.


Key Benefits:

  • Pre-emergent Weed Control – Prevents weed germination before it starts, reducing the need for post-emergent applications.

  • Long-Lasting Residual Activity – Provides extended control for up to 3-4 months, depending on environmental conditions.

  • Selective Action – Controls weeds without harming established turfgrass and ornamentals when applied as directed.

  • Granular Formulation – Easy to apply with a spreader, reducing the risk of drift compared to liquid formulations.

Weeds Controlled:

QualiPro Oxadiazon 2G effectively prevents the emergence of the following weeds:

Grassy Weeds:

  • Crabgrass (Digitaria spp.)

  • Goosegrass (Eleusine indica)

  • Annual Bluegrass (Poa annua)

Broadleaf Weeds:

  • Spurge (Euphorbia spp.)

  • Carpetweed (Mollugo verticillata)

  • Pigweed (Amaranthus spp.)

  • Chickweed (Stellaria media)

    Timing: Apply before weed germination in early spring.

    • Woody Ornamentals Shrubs, Vines & Trees: Application Rate: 100 to 150 lbs per acre

Note: Lightly water after application to activate the herbicide barrier.
