Merit Turf Insecticide at Clare College Cambridge eradicates a plague of chafer grubs

A plague of chafer grubs threaten the lawns of some of Britain’s finest university colleges.

Steve Elstub, head gardener of  Clare College, University of Cambridge has worked with fellow  university gardeners to find a solution.  

Mr Elstub said “The Professional Gardeners Guild and Community of University Gardeners had shared ideas on the chafer grub problem. We’ve come together as a collective of head gardeners at the colleges to discuss how to cope”, he explained.

“It’s been playing havoc with the fine turf at the colleges. Crows, rooks and magpies are tearing big holes in the lawns. There are only a few stone walls between the colleges. We’re like a large estate so if one gets them we all do”.

Around 20 head gardeners are now using Bayer Merit Turf to tackle the grubs. Mr Elstub said using nematodes was useful in small areas but required too much watering to be good for larger lawns.
