Formulation and Mode of Action:

Quali-Pro Oxadiazon SC Herbicide is a suspension concentrate formulation containing 3.17 pounds oxadiazon per gallon. Oxadiazon is a member of the oxadiazole chemical family of herbicides. Members of this herbicide family inhibit protoporphyrinogen oxidase production (PPO inhibitor) in plants and control weeds by killing the young weed seedlings as they come in contact with the herbicide during germination. Seedlings of susceptible weeds emerge from treated soil and then wilt and die. A preemergent application of Quali-Pro Oxadiazon SC Herbicide controls many annual grasses and broadleaf weeds in turf, conifer nurseries, and on a variety of woody ornamental shrubs and trees.

Application Information:

Always apply Quali-Pro Oxadiazon SC Herbicide with a clean and properly calibrated sprayer that will apply the spray solution uniformly. Calibrate the sprayer prior to use according to the manufacturer’s directions and check daily to be certain that the equipment is working properly. Thorough and uniform spray coverage is essential for satisfactory weed control. The spray delivery system should provide a uniform spray pattern with a minimum of drift.

Precautions and Restrictions For Use of Quali-Pro Oxadiazon SC Herbicide:

1. Weed control may be reduced if the product is mechanically mixed into the soil.

2. Do not contaminate water intended for irrigation and domestic use.

3. Do not allow domestic animals to graze treated areas.

4. Do not apply in greenhouses, as plant injury may result from co-distillation of active ingredient onto leaf surfaces in condensate.
