HC Deb 06 December 1951 vol 494 cc281-2W
52. Mr. Hurd

asked the Minister of Agriculture what progress has been made with trials to test the efficacy in this country of the spray treatment of sheep rather than dipping as a method of destroying animal parasites.

Sir T. Dugdale

Trials have been made this year by a commercial firm with the "deluge" type of sprayer, under field conditions, and some success in fly control has been achieved. We are anxious to do some work on the use of sprays for external parasites of livestock but the resources of my Department's veterinary laboratory at Weybridge are limited, and it has not yet been possible to find time for this work.
