It’s that time of year to be on the lookout for brown patch turf disease in Oklahoma lawns. High humidity, excessive moisture, and warmer temperatures are the perfect conditions for lawn diseases such as brown patch to develop.

In order for lawn diseases to occur, there are generally three things that must be present. Those three things include a susceptible host, present fungi, and the right weather conditions. Fungi loves warm, wet, humid weather, which is what we generally experience during this time of year.

As for brown patch, fescue is a good host for this disease and some varieties are even more susceptible than others. Bermduagrass is another grass susceptible to severe brown patch, along with large patch, which is often found on zoysiagrass lawns. Fungi are present just about everywhere and are waiting for the right conditions to grow.

Brown patch will cause yellow to brown splotchy areas in lawns. A turf fungicide can be applied on a preventative and curative basis. But it typically has about a two to four-week residual, so repeat treatments are often needed for best results. In periods of heavy rainfall, make sure you turn off your irrigation system and let the lawn dry out.

If your lawn has been impacted by brown patch turf disease, it’s best to remove the grass clippings when mowing. This will help remove some of the fungi present and allow better air circulation within the turf.
