Fairy-ring
Fairy Ring
View Guide
i

Fairy Ring

One of the more difficult turf diseases to control, fairy ring is caused by any of 60 or more soilborne basidiomycete fungi. The fungi do not directly attack plants, but instead cause problems by stimulating turf and/or causing hydrophobic soils that lead to localized dry spot (LDS).

Gray Leaf Spot

Gray leaf spot is a foliar disease that can devastate ryegrasses but also damage tall fescue. Perennial ryegrass loss can occur quickly, so knowing the conditions for optimal disease development is essential to making the right management decisions.
