Category: Diseases Subject: Red Thread, Yellow Patch, Dollar Spot
Fungal diseases have been relatively minor over the past week. The weather
has been cool and dry and favorable for turf growth. RED THREAD became
quite active in some lawns during the extended rain last week, but this
week's dry air should help the turf outgrowth the fungus unless the fertility
is very low or the soil is very compacted. YELLOW PATCH (cool-season brown
patch) was seen on some golf courses, especially where fertility was high
in the wet weather. Again, this disease should disappear without treatment
or sustained injury. The temperatures are approaching normal in the coming
week, so some of the early summer diseases, such as DOLLAR SPOT, might
begin to develop.
