TRI-BASIC COPPER SULPHATE (53% Copper)—TRI-BASIC 
is effectively used for the control of persistent diseases,

of residue is of particular importance in preventing scale 
infestation. In sprays this fungicide should be used at the 
concentration of one-half or less of the quantity of copper 
sulphate ordinarily used in Bordeaux Mixture. In dusts the 
recommended quantities of TRI-BASIC plus talc or clay has 
largely replaced the old-fashioned Copper-Lime dusts. This is 
especially true where DDT is recommended inasmuch as it is 
generally recognized that the presence of excess lime 
greatly reduces the effectiveness of the insecticide. (6-lb.
