Show Spray Facts for Fruit Growers To give fruit growers a more intimate in-timate knowledge of spraying materials, materi-als, spraying machinery and the why and wherefores of spraying so their operations may be more uniformly successful, a handbook on spraying insecticides and important insect pests has been published by the United States Department of Agriculture as Farmer's Bulletin 906. Orchard spraying, spray-ing, it says, is an exceedingly cheap form of insurance for the fruit grower against the group of insect pests and fungous diseases preventable by this treatment.' Although it may be expensive, ex-pensive, the crop value both as to quantity and quality is so greatly increased in-creased thereby that it is comparatively comparative-ly a small investment. The bulletin contains directions for the preparation prepara-tion and use of the more important insecticides necessary in combating the various insect pests of orchard, vineyard, etc., as well as other information in-formation of use in preventing or reducing, insect losses to these crops. Various types of spraying apparatus, nozzles, etc., are decribed and illustrated il-lustrated with special reference to their use in orchards and home grounds. A ready reference table for dilutions of sprays may be combined and upon what plants they may be used. The bulletin gives an important list of insects in-sects with spraying schedules for their control. Keep Zinc away From Y'our Preserves Do not use galvanized utensils in making preserves, jellies, or fruit juices, the Bureau of Chemistry of the United States Department of Agriculture Agricul-ture advises. Some of the zinc with which the vessels are galvanized may be changed to salt of zinc, which will give the product an acrid and astringent astrin-gent taste and render it unsuitable for ! human use. Moreover, the dissolving of this zinc coating tends to ruin the container. The use of galvanized j utensils for boiling down fruit juice I is especially risky. I w. s. s. |
