Brown Patches of Lawn
Do you want to know why lawns are so eye-catching? It is because of their color uniformity. Single or multi-shaded green lawn soothes your mind intensely. That’s why when brown or large patches cause discoloration, it bugs you the most.

Both the patches showcase the same sort of symptoms but still are separated in some points.
Firstly, they are induced by different strains of fungus- Rhizoctonia solani.
Secondly, Cool-season grasses like Tall fescue, Ryegrass, Kentucky Bluegrass, etc are susceptible to brown patches.
And warm-season grasses like St. Augustinegrass, Centipedegrass, Bahiagrass, Zoysiagrass, Carpetgrass, Bermudagrass, etc are inclined to large patches.
Rhizoctonia solani gets an invitation whenever the grasses remain wet for a long period with the daytime temperature above 26-degree celsius & nighttime temperature around 18-degree celsius
Dead or dying or drying grasses making circular brown or grayish shapes. Often surrounding green grasses give it sunken exposure.
