Spraying Formula for Control Of the San Jose Scale.

Having been asked several times for a solution to spray for the San Jose scale, we submit the following through the columns of your paper, to the public: The lime-sulpher wash easily stands first among the contact insectides, and is the most effective solution which we have for use against Uk scale insects. It is designed pVnarily for winter work, as it is so caustic in its action as to be almost fatal to any kjnd of foliage. The following formula is one that has been thoroughly tested by us and is entirely reliable: Lime, 50 pounds. Sulphur, 50 pounds. Water, 150 gallons. Add enough water to the lime to slack it thoroughly and immediately add the sulphur. Boil for an hour or so, with only enough water to keep the mass liquid, until the solution becomes a deep amber color. After it has all been mixed together, boil for at least another hour, and then add water enough to make up 150 gallons, and spray soon as possible. It is more efficient when used warm, and some of the failures with this wash have undoubtedly been due to the use of stale solutions and to careless boiling. It is always advisable with this or any other spray to wear very old clothing that will never be ÜBed for any other purpose, and to protect the hands and face in some way. Auto-mobile-goggles would serve admirably to keep the spray from the eyes. The lime used in the lime-sulphur wash should be unslacked stone lime, containing just as little sand as possible. The "new process” lime -will give excellent results, but lime and sulphur should never be used in a spray outfit that is operated with compressed carbon dioxide, as the carbon dioxide will precipitate dissolving sulphur Commercial lime and sulphur can ,now be obtained from 9 number of reliable firms ready prepared In a concentrated form, ready to be applied to the trees as soon as it is dissolved. As It comes from the factory this material costs about twenty cents per gallon in barrel lots. It is diluted one to ten, thus making a gallon of spray solution as It goes on the tree, cost two cents. In large lots this cohi can be reduced to one and seventyhundredths cents per gallon. HALLECK NURSERY CO.
