The results of field evaluations of fungicides for the control of stem and leaf rust of wheat at Winnipeg are presented. Economical control was achieved by means of chemicals, especially nabam plus zinc sulphate, provided that the rainfall was not adverse during the period of the spray program. Zineb was as effective as nabam plus zinc sulphate but was considerably more expensive. Four to five applications each of [Formula: see text] quarts (Imp.) nabam (19 per cent) and [Formula: see text] pound zinc sulphate per acre gave effective control. It was extremely important to begin application of the chemicals early, when only a trace of rust was present.The problem of controlling the cereal rusts with protective fungicides is discussed.
