Q.Can You Let Me Know What Is Wrong With My Grass?
Start to get a few random patches of grass going brown and dying. At first, I thought it was just getting enough water but now I’m thinking it is something else like lawn grubs/beetles – I haven’t seen any physical evidence. Or could it be some type of disease? The turf is Empire Zoysia. Any idea what it could be and how to treat it? Thanks Logan

I notice what looks like a plumbing stack. It could be possible that there is a leak, which could keep the soil wet and disease ridden. If this is the only area of grass that you are seeing dying off, then you may consider having that gray pipe looked at. Wet conditions can cause Rhizoctonia root rot to take over. I see the telltale ring of yellow with green in the center. If you are seeing this elsewhere, as well, then it may not be due to the pipe. It could be low places in the lawn collecting extra moisture. Another thing to consider will be overfertilization. Too much nitrogen will invite the disease.
I would turn towards fungicides, though it will not eliminate the issue. To get rid of it, the factors that are allowing it to flourish must be removed.
