FOR SPRING APPLICATION ON GOLF COURSE
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.
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.
For Spring Application On Golf Courses: The 3 lbs. or 4 lbs. a.i./acre rates may be applied as split applications. Weed control and better turf management can be programmed by splitting the a.i. per acre rate of active ingredient into “two” separate applications. For example to accomplish this in a given region of the country using the 3lbs a.i. rate, first apply 1.5 lbs a.i. for the first application 1 to two weeks prior to weed seed germination or in late December or early January; then follow with the second “1/2” rate in 60 days or in March. Do not split the 2lbs a.i. acre rate on the label. The 3 or 4 lbs a.i. per acre rate should not be split if applied to new turf areas 1st under management where weed pressure is expected to be heavy.
