HC Deb 13 July 1955 vol 543 cc185-6W
98. Mr. Kershaw

asked the Minister of Transport and Civil Aviation what experiments have been made by his Department in order to discover a method of permanently stunting, by the use of chemicals, the growth of grass on the verges of roads.

Mr. Boyd-Carpenter

In consultation with the Road Research Laboratory and the Nature Conservancy, I am investigating the control of the growth of grass by stunting agents. It is too early yet for the results to be assessed. On the other hand, experiments in the control of roadside weeds by means of chemical agents have now reached the stage when I am in a position to issue a circular to highway authorities giving guidance on this subject, and this I hope to do very shortly.
