§ Mr. Henderson Stewartasked the Secretary of State for Scotland if he is aware of the deaths caused to animal and bird life by the spraying of potatoes with sulphuric acid; and whether, now that the war is over, he will forbid the use of this poisonous weed killer.
Mr. FraserThe only instance known to me is one in which some young partridges and rabbits were killed or injured by sulphuric acid spray. In view of the importance of this spray in preventing the spread of disease and increasing the yield of seed potatoes my right hon. Friend is not prepared to adopt' the hon. Member's suggestion.
