HC Deb 09 April 1959 vol 603 c34W
Sir A. Bossom

asked the Minister of Agriculture, Fisheries and Food what proposals he has for requiring manufacturers to state the proportion of such substances as aldrin, dieldrin and boron which are contained in their compound fertilisers.

Mr. John Hare

Investigations are being carried out into the possibility of devising satisfactory methods of analysis for the determination of these substances. Further consideration will be given to the matter when such work is completed.
