Lubricating oil emulsion, wettable sulfur with nicotine sulfate, and nicotine dust (2 per cent nicotine) controlled the rosy aphis (Anuraphis roseus), altho none of these preparations were quite so effective as lime-sulfur with nicotine sulfate, which is the standard treatment. The spray mixtures should be applied preferably during the delayed-dormant period, while dust mixtures containing a 2 per cent nicotine will probably give best results when used for the pre-pink treatment. Dust and spray mixtures applied during the pink and calyx periods gave in most instances inferior control.
