| Question: | "Our bowling green contains a number of grey-green patches of coarse grass species which are understand is Yorkshire fog. This is not interfering with play to any significant extent but it does spoil the appearance of the green. Could you please tell us how this grass can be controlled or eliminated?" |

| Answer/Response: | "In the past Yorkshire fog was commonly seen as a weed species in all types of fine turf including golf greens and bowling greens. In the case of golf courses, however, it has been most noticeable in recent years that the grass is far less common in putting surfaces than it used to be. The general reduction in the amount of Yorkshire fog seen in golf course work can be attributable to the more frequent use of triple mowers which have scarifying attachments or thatching reels which are now being used quite frequently - perhaps, once a week or once a fortnight. This therefore very neatly illustrates the fact that Yorkshire fog does not like frequent light scarifying and in your case this would be one method of controlling the weed. Many bowling clubs now possess small rotary scarifiers and if these are used at intervals during the playing season as well as in spring and autumn then Yorkshire fog can be significantly weakened and in some cases almost eliminated. Frequent light raking using a comb attachment on the mower, which means that the green is lightly raked each time it is cut is also helpful in reducing the vigour of Yorkshire fog. Chemical control of the weed grass is not usually a practical proposition due to lack of suitable weed killers which will kill one grass and leave unaffected the desirable finer species. We have, however, had some reports from the field of greenkeepers treating fog patches with aerosol weedkillers with some success. Patches of weed grass should be treated several times during a single growing season with the aerosol weedkiller, preferably based on fenoprop and 2,4-D. Good results cannot be guaranteed but there may be some weakening of the weed. Of course the most reliable method of control is physical removal although this is generally only practical where only a few small patches of Yorkshire fog are present. The coarse grass can be removed using square-cut turf repairer or similar tools such as circular cutters similar to those used for cutting golf holes. golf holes. Turf containing the coarse grass can then be discarded and replaced by turf made up of the desirable fine bents and fescues. This procedure, of course, depends on having good quality turf available to replace the unwanted weed grass patches." |
