. The more important fruit tree diseases of Ontario [microform]. Fruit; Pulvérisation et poudrage en agriculture; Spraying and dusting in agriculture; Fruits; Exploitations agricoles. 22 done early in spring before the buds have started to swell, and care must be taken to see that every bud is thoroughly covered. Success depends upon early and thorough spraying, as can be understood from a consideration of the life history of the fungus. Somewhat weaker solutions of lime-sulphur or Bordeaux mixture will prevent the Leaf-Curl, but will not kill San Jos6 Scale, which is apt to be found wherever peaches are grown, and therefore it is advisable to use the strong solution of concentrated lime-sulpliur as recommended above. Fall spraying for the prevention of Peach Leaf-Curl has been tried in New York State and satisfac- tory results obtained. The results of experiments in Ontario in the fall of 1915 and again in 1916 point to the same Peach Leaf-curl. Peach Yellows and Little Peach. Thi'sc two disea-ses are so closely in the orchard and seem to be so nearlv n-lnti'd that they may be discussed together. Tliey are both very destruc- tive and are much feared by all peach growers who have had an opportunity to see the damage they can do. From about the year 190!) to 1913 these diseases were so prevalent in the Niagara district that there was something like a panic among the growers lest the peach industry might soon be ruined. At that time the writers saw several (itherwise excellent orchards varying in size from 500 to 1,000 trees, in which almost every tree was diseased and thus worthless; for there is no cure for a tree once it is diseased. Some of tiiese orchards were not more than eight years of age. and so had not reached their prime. Fortunately, a better knowledge.
