This article presents the results of several fungicide spraying trials on the degree of Leaf Mould controlled in nurseries in Yorkshire and Lancashire, England from 1949 to 1952. All copper fungicides are about equally efficient, but colloidal copper with a white oil emulsion is preferred as it leaves no visible deposits on the fruit. Of the non-copper fungicides, salicylanilide and zineb are outstanding, while thiram, glyoxalidine and ziram give some control. Ziram has the drawback that it leaves a heavy deposit on the fruit. Nabam with zinc sulphate was the only spray to remain efficacious in severe epidemics.
