Maintaining a lush, green lawn greatly enhances a landscape's attractiveness. However, the presence of brown patch disease, recognizable by the emergence of brown patches and the gradual browning of leaves, can be problematic.
Brown patch disease is commonly seen in cool-season turfgrasses, particularly tall fescue, and occasionally in hybrid bermudagrass and zoysiagrass. It tends to appear in hot, humid weather, especially when night temperatures exceed 60 degrees Fahrenheit and the foliage remains wet for extended periods. Several environmental factors can worsen the severity of this disease, including poor soil drainage, limited air circulation, overwatering, and high nitrogen levels.
Good management practices are crucial to reducing the risk of brown patch disease. These include avoiding excessive nitrogen application, judicious fertilizer use, reducing prolonged leaf wetness, sharp mower blades, and applying effective fungicides when needed.
