Firm to trial bleeding canker ‘cure’

Arboriculture specialists may have found a cure for bleeding canker in horse chestnut trees, Horticulture Week reports.

It says arboculturalist consultancy Jonathan Cocking Associates (JCA) will trial a newly patented product with English Heritage.

JCA managing director Jonathan Cocking said he was trademarking the product, which kills canker bacterium in trees’ vascular systems.

Plugs of bark are removed around the chestnut, he explains, and a tree infusion is screwed into the holes.

The process takes an hour and after a year the tree refoliates, he adds.

“We are rolling it out with a few high-profile programmes including one with English Heritage.

“The treatment is invasive, but it’s a natural product.

“It’s better to get cracking and save a few trees than run a 10-year study programme only to find at the end of it that all the horse chestnuts have died.”

JCA, based in Halifax, West Yorkshire, has worked with a Dutch firm on the cure and hopes to license the product later in 2009.
