%X Between 1960 and 1963, four preliminary experiments on herbicides for cotton were carried out at Kimberley Research Station. Diuron, applied pre-emergence at rates of 1/2-1 lb an acre active ingredient (a. i.), and dicryl, applied seven to ten days after emergence at rates of 3-6 lb an acre a. i., gave satisfactory weed control. Diuron, because of its longer residual action (six weeks in early wet season, two months or more in late wet and early dry season) is preferred, and is recommended as the standard herbicidal treatment for Ord River cotton crops.
