Diseases

A structural quality performance standard which states the maximum amount of disease, as a percentage, in the surface being maintained. The standard can be qualified to also state some specific diseases for which the acceptable maximum percentage content might vary. For example, for Red Thread, a content of 20% might be acceptable, yet for Fusarium Patch it might be given as 2%. Fairy ring type 2 might be qualified as being acceptable to 100% of the surface, with a proviso that attention is given to removing any fruiting bodies by hand and application of sulphate of iron, or similar, to green up the sward to match that of the green ring produced by the fungal ring activity.
