Control of Cherry Leaf-Spot

Description: "The leaf-spot of the cherry seriously injures both sweet and sour varieties of that fruit in many sections of the eastern half of the United States. It is caused by a fungus which lives through the winter on the fallen leaves and infects the new leaves in the spring. The best control of this disease is obtained by spraying with a diluted lime-sulphur solution or with Bordeaux mixture 1) as soon as the petals fall, 2) about three weeks later, and 3) directly after the fruit is picked." -- p. 2
