Great Mixture To Keep Weeds Out Of Infields And Warning Tracks

With summer now upon us, many high school playing surfaces are winding down from spring play. Now, crabgrass, goosegrass, and other unwanted growth will appear.

How do you control this issue? 

A simple mixture of glyphosate in a 2% solution and SureGuard at 3 teaspoons (or Bayer’s Speticle at 1.65 fluid teaspoons/8 ml) per 1000 sq ft. So, in a 3 gallon spray hand can, 7.68 ounces of glyphosate and 9 teaspoons of SureGuard (or 4.95 fluid teaspoons of Speticle/24 ml). The tank will cover 3,000 sq ft. How well does it work? The photos below are from the warning track at Brebeuf High School, using glyphosate and Sureguard. The track was sprayed in March.

Note: the weeds along the track edge. This is due to the application. As many of you know, glyphosate is a non-selective herbicide, meaning it will kill anything it touches. So, be careful along all grass edges. Finally, to get better control, try not the work the infield/track up as this will break the Sureguard barrier.
