| Question: | "Quite recently we have noticed the rapid development of a layer of a green slimy substance on various parts of the course, particularly on well used traffic routes. Certain areas (though relatively small in size) are now so affected that they are positively dangerous to walk on. I enclose a plug of affected turf and would welcome your comments and recommendations for treatment." |

| Answer/Response: | "We have received a number of similar samples from clubs in your locality and, in common with the others, yours has been found to contain a mixture of algal species but primarily a eukaryotic green alga, Dactylothece braunii. Like all algae, this species is associated with wet conditions - although it is generally uncommon on turf it is locally abundant under the right conditions, i.e. when the turf is particularly wet for long periods, especially under mild autumn conditions. Due to the fact that this alga possesses thick gelatinous sheaths, it can resist drying out to some extent (unlike most algae) but is killed by prolonged desiccation. Rapid multiplication does occur when conditions are right, as they obviously are now - dispersal from one site to another could possibly be by means of birds or humans. It is not usually harmful to the grass and as colder and drier conditions develop, it should die out. In the meantime, as the alga is particularly troublesome, it may be brushed off the affected areas to give a better foothold. If it continues to be a problem, one rather inexpensive treatment would be an application of sulphate of iron at a rate of say 8 g/m2 (1/4 oz. per sq. yd.), suitably bulked with a carrier such as sand. As an alternative, you may care to try a mercury fungicide or an algicide called dichlorophen which is available as a proprietary mosskiller. In the long term, particular attention should be paid to easing any compaction resulting from heavy use with the aim of improving surface drainage and thereby producing drier surface conditions (unfavourable to the development of algae). To this end, spiking and sanding will be required. The need for additional drainage work should not be overlooked." |
