Gains to the Grower from Weed Science

  • J. R. Hay (a1)


First of all I would like to bring greetings from the Canada Weed Committee (CWC). Under one name or another this Committee has met every year since 1929 when it was organized by a handful of workers to coordinate their tests with sodium chlorate, sodium arsenite, sulphuric acid, etc. The CWC still meets as a working planning committee to review current work, up-date recommendations and coordinate testing for the forthcoming year.
