Hello, Last summer I started to see a few spot of dead grass at one end of my yard. The grass would die, but would turn almost white or a really light beige color. Upon inspecting I would see little spore like capsules inside the dead spots. I took it to the local Lessco dealer to find out if it was a fungus or what, but the told me to just apply some pre-emergent weed killer or barrier in the spring. I took their advice and said OK, but after the snow melted from two large snow falls in Maryland, i found even more dead patches that earlier were healthy. Can anyone tell me what this is before I loose my yard?
