| Question: | "We have been troubled this season by small sunken patches, usually about 6 to 8 in. across, which have appeared on a number of our golf greens. The soil immediately below these patches has the same musty odour that one finds in fairy rings and white "spawn" is also sometimes present, so it would seem obvious that some kind of fungus is involved. A plug of turf taken with a hole-cutter from one of the affected areas is enclosed for examination." |

| Answer/Response: | "The causal fungus has been identified as belonging to the basidiomycetes, a group of fungi which also include the fairy ring toadstool - producing organisms. The particular fungus found on your greens is usually termed a "Superficial Basidiomycete", a rather unsatisfactory name applied to a number of fungi which produce a variety of depressed, yellowed or stimulated patches on fine turf. In your case the fungus is feeding on the layer of accumulated fibre present, breaking it down and so producing depressions in the surface. One method of lessening the effect of the fungus is therefore general fibre removal by scarification and aeration. Like related fairy ring fungi, this Basidiomycete is waxy and difficult to damp. Fungicide treatment can therefore be ineffective unless steps are taken to ensure maximum contact between fungus and fungicide. Affected areas should therefore be closely hand forked and an organic fungicide then applied at double the normal rate, using plenty of water to wash the material into the surface. Alternatively, diseased patches can be physically removed by means of a hole-cutter if the areas are small and distinct enough to be so dealt with." |
