In the Dallas Ft Worth area Brown Patch is showing up again due to the excess rains and cool temps. It starts with a yellow spot and then in a week, turns into a big circles in the lawns.When people keep their lawns wet most of the summer it raises the pH and makes perfect environment for fungus. Oct is the 2nd rainiest month of the year and the ground is saturated so spores are flying everywhere looking for a host. Only the weakest yards-- the ones that are over fertilized, and over watered, during the Summers get it. Once you get, you got it forever because it will lie dormant until the right conditions arise, and Boom shows up again. It is found mostly in the wealthy neighborhoods because they water too much and fertilize every year. No fungicide can stop it so far in the last 15 or 20 years, so don't waste your money on it. I've seen a lot of money wasted on fungicide and it doesn't work.
