SPRAYING ADDS TO FRUIT YIELD
Cure of Orchard Disease Explained In Article By State Food Director. . By State Food Director Christie. In the campaign for a greater food production in Indiana the farm orchard should receive attention. Ap£les are no longer considered a luxury nt a necessity and an important food. The practice of canning, evaporating and drying apples makes it possible to have this fruit throughout the whole year. The summer sprays have for their purpose the control of plant diseases, such as the black rot, apple scab, bitter rot, leaf spot, apple rust, apple blotch, sooty blotch and fly speck fungus and the control of. the insects already mentioned. The standard materials used in the summer sprays for apples are lime sulphur, Bordeaux mixture and arsenate of lead. Nicotine sulphate is added when the occasion demands, for soft bodied insects such as plant lice. The first summer spray is applied to control apple scab, curculio, canker worms, etc. Use Bordeaux mixture (4-6-50) with one pound of powdered arsenate of lead or two pounds of paste arsenate of lead to fifty .gallons of Bordeaux mixture. Apply when the leaf .buds burst, taking care to finish before the flower buds open. The second summer spray is the important spray in the control of the first brood of codling moth. Use diluted lime sulphur solution at a strength of one degree Baume, which is approximately one and one-quar-ter gallons of comniercial concentrated lime sulphur solution to fifty gallons of water, to which is added one pound of powdered arsenate of lead or two pounds of paste arsenate of lead. Apply this just as soon as the petals fall. It must be remembered that the calyx cup begins to dose when the petals fall and since the majority of the apple worms, which hatch from the eggs of the codling moth, enters the apple at the Calyx end, it is extremely important that some of the spray solution be forced into each calyx cup. If plant lice are infesting the leaves, they may be controlled by adding one-third pint of nicotine sulphate to every fifty gallons of spray solution. .
