We sprayed two preventive
applications in September and October and today are in the process of making
our Spring Application of Triton Flo at .75 Oz per 1,000 sq feet. The Zorro Fairways are emerging from dormancy
and the weather conditions have been very favorable for the development of
Zoysia Patch.
Zoysia patch, caused by Rhizoctonia
solani, is the most common disease of zoysiagrass in our region. Symptoms are
most common in spring and fall as zoysiagrass enters or breaks winter dormancy.
The patches range from just a few feet across to 20 feet or more. Circular areas of thin, tan zoysiagrass initially
develop in late September to early October during cool, rainy weather and again
in April and May. Leaf blades, particularly those near the patch edge, may
develop a yellow orange color, causing an orange margin. The symptoms will fade as temperatures
increase in summer, but often reappear in the same areas when conditions become
more favorable.
