Not illustrated. 1915 edition. Excerpt: ...quantities results in a better mixture than when they are carelessly mixed, or when the whole mass of one solution is poured bodily into the whole mass of the other. Always stir the solution well before dipping out, so that the liquid you take out shall be fully charged with the ingredients of the solution. Adding the P0i$0n.--The arsenate of lead paste is first dissolved in just enough water to make it liquid and is then stirred into the Bordeaux Mixture. It is then ready to apply. If the powdered form of arsenate is used, use only half the amount by weight. Strain Before Using.-...Before using, the mixture must be carefully strained through a cloth or fine wire gauze. Remember that all the spray must come out through the small hole in the end of the nozzle; therefore, to avoid clogging, strain carefully before using. Care in the thorough straining before spraying will pay for the trouble many times over. If one uses considerable quantities of the mixture, it is well to have a large funnel strainer made, fitted with two nettings, one of iron wire windowscreening and the other with much finer guaze, preferably of brass. Having strained the poisoned mixture, it is ready to apply. SELF-BOILED LIME-SULPHUR WASH. The tests of the United States Department of Agriculture indicate that this is the best material to use on peaches in all treatments when there is fruit or foliage on the trees. Some growers use it on apples instead of Bordeaux or commercial washes. The slaking lime does the boiling, no fire being used in boiling the wash itself, though hot water is used for slaking the lime. Stone lime (unslaked) __________________ __ 8 pounds.
