Colorado, with its breathtaking vistas and diverse landscapes, is undeniably captivating. However, the state's distinct climatic features and soil profile have inadvertently made it a hotspot for Necrotic Ring Spot activity. Colorado experiences a semi-arid climate. Warm summers and relatively cool but dry winters can place lawns under prolonged stress. Stress, in turn, makes turf more susceptible to diseases, including Necrotic Ring Spot. Many regions in Colorado feature clayey soil. While clay soil can retain moisture, it can also lead to compaction, restricting root growth and reducing the grass's ability to absorb essential nutrients. This limited nutrient uptake can weaken the lawn, making it an easier target for diseases. The sporadic rainfall in Colorado often compels homeowners to rely on irrigation. However, inconsistent or over-watering can create an environment conducive to fungal diseases. NRS thrives in moist conditions, especially when water remains stagnant due to compacted soil. Kentucky Bluegrass is a favorite among Colorado homeowners for its resilience to colder temperatures. However, it's also one of the primary grasses vulnerable to NRS, making many Colorado lawns susceptible to outbreaks. Necrotic Ring Spot is a soil-borne fungus. Once a lawn is infected, the fungus can remain in the soil, waiting for optimal conditions to strike again. This 'disease memory' means that lawns can experience recurrent outbreaks once affected if not treated appropriately.
