Record of Sprays
Mr. Mason says that 10 per cent of the orchards in Missouri and Kansas produce 90 per cent of the apples of a marketable type. His aim from the start was to have as near a 100 per cent producing orchard as possible. “I sprayed first in the spring at cluster bud time,” he says, “when the first leaves were about the size of a mouse’s ear. That was primarily for scab. I used one-gallon of lime-sulphur solution to twenty-five gallons of water.
“I sprayed the second time just as the blossoms were dropping. That was for the codling moth. I used one gallon of lime-sulphur to forty gallons of water, with two pounds of paste arsenate of lead, or one pound of dry arsenate. The third spraying was the same as the second, and was applied two weeks later to control the curculio. The fourth spraying was done about the first week of July, using the same formula as in the second and third applications, to control the second brood of codling moths and side worms. If cankerworms are prevalent I use three pounds of paste arsenate of lead, or half in dry form, to fifty gallons of water.
“That is the spring spraying. If the San José scale is present, the trees must be treated in winter, after the leaves drop and before they make their appearance in the spring, spraying once with a strong solution of lime-sulphur in proportion of one part of lime to ten parts water. This application is very good.”
