For lawn and turf disease, submit a 3-4 inch diameter plug taken where the healthy and diseased areas meet so the sample will contain both diseased and healthy turf. Take the plug 2-3 inches deep and include the adhering soil. Enclose plugs in a plastic bag. Do not add additional moisture. Paper towels or crumpled newspaper should be used as a cushion inside the shipping container.
Overnight shipping is preferred, but if regular mail is used, send the sample early in the week.
