| Question: | "Towards the end of the summer we noticed very high populations of crane flies, a white clubhouse wall was often coloured black with daddy long legs. We are most concerned that severe damage to areas of fairway in the spring may be the result of the great numbers of adults this year. Should we be prepared to spray the fairways and if so, what can we safely use?" |

| Answer/Response: | "The larvae of crane flies (leatherjackets), feed throughout the autumn and winter during mild weather, feeding particularly voraciously in the spring with the return of warmer weather. It is at this time that the most severe damage is usually seen, the leatherjackets feeding on grass stems at or just below ground level. On heavily infested, established turf bare patches appear where plants have been destroyed, these areas quickly filling in with weeds. In other cases, the first signs of infestation are either straw coloured areas of grass debris or pieces of fibrous turf torn up by birds looking for food. If poor, weak areas are seen in the early spring with accompanied bird activity (usually rooks or starlings), leatherjacket damage should be suspected. Attention to fibre reduction can reduce leatherjacket activity, as decaying vegetative matter is a food source. Therefore, attention to fairway aeration and scarification treatments can be preventative measures. A hard winter and most particularly heavy spring frosts may reduce leatherjacket numbers significantly so do not automatically reach for the insecticide bottle. However, where visible signs of damage are evident and where leatherjackets can be easily found then chemical control measures are justified. Under the Control of Pesticides Regulations 1986, current MAFF approved insecticides for the control of leatherjackets include those with the active ingredients gamma-HCH, gamma-HCH and thiophanate methyl and chlorpyrifos. When using pesticides follow the manufacturers instructions on the label carefully, remember your obligations as a user of pesticides." |
