Necrotic ring spot prevents your turf from absorbing water properly.

A lawn in Grand Junction, CO, affected by necrotic ring spot.

When your lawn is subjected to cool, wet conditions, it might be at risk for necrotic ring spot! This lawn disease is a fungal infection of the root system and makes it difficult for the grass to absorb water. It thrives in compacted soil, especially when temperatures are between 60-75 degrees Fahrenheit, and the heat of summer and drought can intensify its symptoms. Some common symptoms of necrotic ring spot are light, green spots on your turf, which eventually grow into large patches ranging in size from about 1 to 3 feet. The infected grass will turn reddish brown or bronze before resembling straw surrounding a small patch of new grass growth. If left untreated, it's possible for your turf to die, leaving a depression in your lawn where the infection was.


Brown patch causes brown, circular patches of infected turf.

Extended periods of hot, humid weather might leave your lawn more susceptible to brown patch! Brown patch is a type of fungus that can cause small patches of gray cotton to grow on your turf. This disease often develops when the grass is wet for 10 hours or more while temperatures at night are above 70 degrees Fahrenheit with daytime temperatures above 90 degrees Fahrenheit. The symptoms can be intensified in areas of shade and when there's poor soil drainage paired with over-watering. Some typical symptoms you might see are brown, tan, or orange circular patches of turf with a dark brown border. These patches can range in size from about 6 inches to several feet. Grass blades affected by brown patch will eventually dry out, turn brown, and possibly die.

If conditions remain ideal for brown patch and it's not treated, it can quickly spread and affect large areas of your turf.

Ascochyta leaf blight can cause your turf to turn white.

Ascochyta leaf blight is a lawn disease that commonly affects lawns in the Grand Junction, CO, area. This lawn disease causes yellow lesions on your grass when in the early stages and often resembles frost injury or drought stress. Your turf is at a higher risk of Ascochyta leaf blight when in a shaded area with extended periods of wetness. Cool to moderate temperatures intensify its growth as dew and water won't dry as quickly and if the disease is allowed to progress, the grass will eventually turn white and die.
