As you may have guessed, these brown parallel lines are tire tracks.
This NFL practice football field is Patriot bermudagrass overseeded with
ryegrass. The field directly next to this field is also Patriot bermudagrass;
however it is not overseeded with ryegrass. The Sports Turf Manager
applied a Sulfonylurea herbicide to the bermudagrass field to control Poa
Annua weeds and to clean up ryegrass in the non-overseeded field. After
the application, someone with a utility vehicle decided to take a shortcut
across the sprayed field and continued across the overseeded field, track-
ing the Sulfonylurea herbicide across the ryegrass. A few days later, the
damage appeared and remained visible through the winter months. The
Sports Turf Manager tried to mask the lines with another light overseed-
ing, however this area is a high traffic area for the defensive line and the
seed was trampled as soon as it germinated. Once the springtime came,
the bermudagrass came out of dormancy and the lines disappeared.
