§ Miss Richardsonasked the Minister of Agriculture, Fisheries and Food whether oak wilt disease constitutes a threat to the countryside; and what measures are being taken to counter it.
§ Mr. WigginOak wilt disease is known to occur only in the USA and the likelihood of transmission to this country is assessed by pathologists, both American and British, as extremely remote. The potential risk lies in the bark, and the Importation of Wood and Bark (Prohibition) (Great Britain) Order 1977 requires that oak from North America must have the bark removed prior to shipment; additionally the wood must be either dried or disinfected.
A proposal to extend similar controls to include square-edged sawn oak wood from the USA has been provisionally agreed in Brussels and, subject to ratification, will be included in the EEC plant health directive which is due to be implemented later this year. These additional 540W measures will reduce the risk even further.
