Answer: Z-52 is also called Meyer Zoysia. The most serious disease likely to damage Meyer Zoysia is Brown Patch (rhizoctonia fungus). Leaf Rust is a lesser problem. Grubs and bill bugs (plus moles, crickets in the lower South) are soil borne insects, which can cause serious damage. Start by inspecting the brown areas. Try to pull up the sod. Grubs can feed on the roots and if you can roll up the brown areas and they have no roots, grubs are the problem. Inspect the leaf blades of signs of fungus or spots of rust. If you find them, a fungicide should help. Look at the soil after you've removed some of the sod to see if you can find other insects or holes in the soil. Hope this information helps you determine just what the problem might be. Good luck with your lawn!
