§ Lord Ashley of Stokeasked Her Majesty's Government:
Whether they will list (a) the reports of the Pesticides Usage Survey Group which refer to the use of benomyl; and (b) the studies considered by the Advisory Committee on Pesticide which have indicated clear safety levels for birth defects in relation to the use of this chemical.
