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
