FOR CRABGRASS CONTROL

General Information

General Information Usage on Turfgrass

PRO-MATE RONSTAR 0.67% PLUS FERTILIZER may be used at full rate or as split application in established Perennial Bluegrass, Bentgrass (see restrictions), Bermuda grass, Buffalo grass, Perennial Ryegrass, St Augustine grass, Seashore Paspalum, Tall Fescue and Zoysiagrass turf, at apartment/condominium complexes, corporate and public parks, golf courses, sod farms, athletic fields, playgrounds, cemeteries and other ornamental recreations turfgrass areas. Not for use on home lawns. The turf should be free of leaves and thatch and in condition to allow granules to reach the soil surface. Know the square footage of the areas to be treated and uniformly apply using a granule spreader. Do not apply to turf when it is wet. When using a full rate do not overlap spreader applications, especially on St. Augustine grass since discoloration “streaking” may temporally occur from the “doubled” rate. PRO-MATE RONSTAR 0.67% PLUS FERTILIZER is a pre-emergence herbicide and must be applied prior to weed seed germination. It will not control growing weeds.

USE PRECAUTIONS

Do not use on Red Fescue, Dichondra, or Centipede grass because damage will occur. Do not use on Putting Greens or “Tees” due to varying cultural practices used.

HOW TO APPLY

For best weed control, rake the area free of leaves and thatch and mow if necessary so that granules will reach the soil surface.

Measure the area to be treated and uniformly apply the required amount using a fertilizer spreader (see Spreader Settings chart). Do not apply to turf when it is wet. Do not over-lap spreader applications on St. Augustinegrass, as discoloration “streaking” may temporarily occur from “double rate.” After applications, if rain is not expected within 24 hours, sprinkle the treated turf with 1/4 to ½ inch of water to get maximum weed control.
