HC Deb 08 July 1959 vol 608 c137W
Sir A. Bossom

asked the Minister of Agriculture, Fisheries and Food if he will advise the manufacturers of chemical soil sterilisers to give more explicit instructions as to the application of their products, in view of the damage to young tomato plants recently caused by the use of such a steriliser.

Mr. John Hare

Reports of such damage have been made following the recent introduction of various formulations of chemical soil fumigants based on sodium methyldithiocarbamate. The commercial interests concerned and my own scientific and technical staff are investigating the conditions under which damage occurs to plants subsequently set out in treated soil. It is hoped that the revised instructions which will result from these investigations will greatly reduce the difficulties presented by the use of this chemical.
