Turf Disease Control
Lawn and turf diseases can occur when weather and/or lawn practices favor disease development. Very often, hot and humid weather contributes to diseases. Excess moisture, such as is provided from watering a lawn in the afternoon instead of the early morning hours can cause diseases as well.
Luckily, lawn diseases can be treated with a few different approaches. Sometimes an application of fertilizer can give the grass what it
needs to outgrow the disease. Changing lawn practices such as watering amounts and times and cutting the grass at the appropriate length
(3-3 1/2") can also help with lawn fungus. If neither of these methods will help, sometimes a lawn fungicide treatment is necessary and
will eliminate the problem.
Below are some of the most common turf diseases that we deal with in this region.
Red Thread:
Red Thread is a fungus that can cause spots in the yard as pictured above. These can appear yellow to brown in color, but upon closer inspection, you will see that they are actually red or pinkish in color. Red thread can be treated with an application of fertilizer if it is mild, but may require a fungicide treatment if it is more severe.
Dollar Spot:
Dollar Spot fungus appears much like red thread from a distance, but is much different when you examine it from closer. As you can see in the picture on the right, the disease makes an hour-glass shaped lesions on the grass blade. A fungicide is often required to control dollar spot.
Leaf Spot:
Leaf Spot can cause yellow or brown spots in the yard. If you look closely there are black spots on the blades of grass which is the fungus. Leaf spot can be corrected with a lawn fungicide.
Rust:
Rust is a fungus that appears when the weather is hotter. It is most easily identified in the way in which it turns your shoes orange when the affected areas are walked through. Many times the condition can be corrected with an application of fertilizer, but severe cases may require a fungicide treatment.
