§ Mr. Ron DaviesTo ask the Secretary of State for the Environment what consultation he has had with the National Rivers Authority to take steps to prevent the contamination of water courses by the fungicide Tecnazene.
§ Mr. Baldry[holding answer 11 November 1991]: With the cooperation of the National Rivers Authority my Department has carried out a survey of Tecnazene and its metabolites in rivers and effluents from potato washing and processing. The Ministry of Agriculture Fisheries and Food has suggested a provisional water quality standard of 1 microgram per litre for tecnazene. The results of the survey, and the NRA's data, have been submitted to the Advisory Committee on Pesticides which is currently reviewing the registration of this fungicide.
