Turf diseases (fungus)
Turf diseases do occur in our area. The most prevalent are Red Thread and Microdochium Patch, (aka Snow mold, Fusarium patch) We have treatments available that will prevent or cure existing fungus problems.
As a rule, we do not include fungus treatments in our annual programs because of the transient nature of turf disease. However, chronic Microdochium Patch disease has become a problem due to weather conditions the last few years. Therefore we are recommending preventive treatments for Microdochium Patch in October/November and December/January. Red Thread infection is usually related to nitrogen deficiency but can be a problem even on lawns where nitrogen levels are adequate. We can provide very effective control for Red Thread, and treatments can be added to a program or applied separately should a problem arise.
Here is a great tool to use for turf disease identification from MSU
Microdochium patch (Microdochium nivale) (sometimes referred to as Fusarium patch in older references) is problematic from fall through early-summer in areas west of the Cascade Mountains. The Pacific Northwest can be the ideal climate for Microdochium patch given the long dew periods, frequent rainfall, and cool, wet weather that persists for much of the growing…Read More
Red thread disease is a fungal infection found on lawns and other turfed areas. It is caused by the corticioid fungus Laetisaria fuciformis and has two separate stages. The stage that gives the infection its name is characterised by very thin, red, needle-like strands extending from the grass blade. These are stromata, which can remain…Read More
