General Information

GENERAL INFORMATION

Not for use on home lawns.

One water-soluble packet is equivalent to 1 pound of product, which equals 1/2 pound of active ingredient.

Quali-Pro Oxadiazon 50 WSB is a preemergent herbicide for control of many broadleaf weeds and annual grasses in turf and on a variety of woody ornamental shrubs and trees. Quali-Pro Oxadiazon 50 WSB controls weeds by killing the seedlings of young weeds as they come in contact with the herbicide during germination.

Make applications with a properly calibrated sprayer that will apply the spray solution uniformly. Uniform application is essential for satisfactory weed control. Calibrate the sprayer before using, according to the manufacturer’s directions, and check the equipment daily to assure that it is working properly.

Application Rates: Do not use more than 12 pounds (12 packets) of product per acre per year except in areas where there is heavy weed infestation. In areas of heavy weed infestation, the maximum application rate is 16 pounds (16 packets) of product per acre per year. Do not apply more than 8 pounds (8 packets) of product per acre per application.

Wherever a range of application rates are listed on the label (for example: “4-6 water-soluble packets”), use higher rates of Quali- Pro Oxadiazon 50 WSB where heavy weed pressure is anticipated, or where medium- or fine-textured soils exist. Soil textures are defined as follows:

- Coarse: Sand, sandy loam, loamy sand

- Medium: Loam, silt loam, silt

- Fine: Sandy clay loam, silty clay loam, clay loam, sandy clay, silty clay, clay

Lower rates may be used on light (coarse) texture, low organic matter (< 1.0% OM) soils; however, these guidelines are intended as general information only. Consult the list of annual grasses and broadleaf weeds below for rates used to control specific weeds.

When a range of spray volumes is recommended, use a sufficient amount to ensure adequate spray coverage under your use conditions. Generally, larger plants require larger volumes.

GENERAL HANDLING INsTRUCTIONs

Each Quali-Pro Oxadiazon 50 WSB water-soluble bag is sealed within a plastic outer sleeve. Do not break the seal until ready to use.
