ORNAMENTALS AND CONIFER NURSERIES ON COMMERCIAL PROPERTIES - ANNUAL GRASSES

General Information

GENERAL INFORMATION

RONSTAR FLO HERBICIDE is a selective, preemergent herbicide for control of many annual grasses and broadleaf weeds in turf and on a variety of woody ornamental shrubs and trees. RONSTAR FLO HERBICIDE controls weeds by killing the young weed seedlings as they come in contact with the herbicide during germination.

Apply RONSTAR FLO HERBICIDE with a properly calibrated sprayer that will apply the spray solution uniformly (uniform application is essential for satisfactory weed control). Calibrate the sprayer prior to use, according to the manufacturer’s directions and check daily to be certain that the equipment is working properly.

Do not allow domestic animals to graze treated areas. Avoid contamination of water intended for irrigation and domestic use.

Limitations, Restrictions, and Exceptions

WOODY ORNAMENTAL SHRUBS AND TREES, CONIFER NURSERIES, AND ORNAMENTALS ON COMMERCIAL PROPERTIES

Apply prior to weed seed germination, as a directed spray to the soil surface or as an over the top spray only on labeled species. RONSTAR FLO HERBICIDE can be applied to both newly transplanted and established plants. Application can be made to actively growing or dormant plants. However, RONSTAR FLO HERBICIDE should not be applied during bud break or during the 4 weeks after bud break.

Rainfall or overhead irrigation (one-half inch) immediately after application will improve weed control activity. Rainfall or overhead irrigation immediately after over the top sprays is required to move the RONSTAR FLO HERBICIDE from the foliage to the soil surface.

RONSTAR FLO HERBICIDE should not be mixed into the soil. Cultivating or disturbing the soil may reduce the weed control activity of RONSTAR FLO HERBICIDE. Do not apply in greenhouses as plant injury may result from co-distillation of RONSTAR FLO HERBICIDE active ingredient onto leaf surfaces in condensation.

In areas of heavy weed infestation, the maximum amount of product allowed per year is 7.4 fl. oz of product per 1000 sq. ft. (2.52 gallons of product per acre per year) (equivalent to 8 pounds ai/A/year). For best results, water-in product as soon as practical after application.
