I installed new Ky Bluegrass sod around the edges of our local high school baseball field in Sept. Everything looked great until last month. (Nov) I started seeing brown streaks developing around the edges. I spot sprayed Round Up on some grass and weeds that were developing in the skinned areas of the infield in late Oct. These streaks look like over spray but I never saw them until a month after I sprayed. Water washes from the skinned area into the grass where these streaks are located. Do you think Round Up caused this or is it something else? Will I be able to make these areas green by April? I'm in north central Ky.
