This should be followed up by a summer treatment, consisting in the application of either the Bordeaux mixture or modified Eau céleste. Formulas and directions for the preparation of these and other fungicides are given on pp. 17 to 19. The Bordeaux mix ture presents one very decided advantage over the modified Eau céleste, in that it contains no ammonia, hence does not dissolve the arsenic compounds, and can therefore be used in conjunction with Paris green or London purple to prevent the attacks of the codling moth as well as of the scab fungus. The mixture should be made in the proportion of one pound of the arsenic compound (paris green or London purple) to 100 gallons of the fungicide, the former being stirred to a smooth paste with a little water and added to the latter.
