At a meeting of the Michigan Horticultural Society, W. A. Brown of Benton Harbor said growers in that vicinity had for three years practiced spraying apple trees with Paris Green with great success. Sprayed on just after the blossoms fall, the poison seems to kill off the brood of moths that survives the winter. This brood is small, comparatively, the main damage being done by the later hatchings. The effect has certainly been marvelous in making apples perfect, even when the adjoining orchards were not treated - showing that the moths migrate but little. There is danger of injury to trees by use of too strong solution. He used one pound to 50 gallons of water, but half the quantity is sufficient. W. N. Cook spoke of the danger to the operator. Do not allow the spray to be blown back against you.
