§ Mr. H. Clarkasked the Minister of Agriculture, Fisheries and Food whether, in view of the recent warning which he issued on the use of Dieldrin, Aldrin and Heptachlor, he will make a statement on the use, as an alternative seed-dressing, of Kotol, which is based on the toxic chemical gamma B.H.C.
§ Mr. SoamesSeed dressings containing gamma BHC have been extensively used since the war to control wireworm and other insect pests, but I understand the manufacturers of Kotol do not recommend its use against wheat bulb fly. There is no evidence to suggest that gamma BHC has caused any appreciable casualties to wild life and its use in seed dressings was not therefore restricted under the recent arrangements affecting dieldrin, aldrin and heptachlor.
