Show solve 40 pounds of copper sulphate in 40 gallons of water, and in a box slake 40 or 50 pounds of linie. This can bo kept as long ns ono desires. When needed, measure out 4 gallons of the copper sulphate sul-phate solution, and add some of the slaked lime until no change in color col-or can be produced by tho test given above. The mixture . will then be rendy for use when diluted. The strength of Bordeaux can be varied to a considerable degree. The above formula is about as strong as we care to use at anytime, any-time, and, after the second application, appli-cation, it is our custom to reduce it by using 50 and even GO gallons cf water for the four pounds of copper sulphsto and three of lime. This can be done, with no apparent appar-ent loss in the efficacy of the Bordeaux, Bor-deaux, when the fungi are not particularly par-ticularly troublesome, and when several applications are to be made at frequent intervals. If the lime is fresh and a proper amount is added add-ed after it has been carefully sink--ed there is no danger of burning tho foliage with Bordeaux mixture. It is moreover, one of the least expensive of the fungicides, and if strained through two thicknesses of burlap before being placed in the barrel from which it is )ump-ed, )ump-ed, it will not clog the nozzle It is generally conceded to bo the most effectual of all the fungicides, its efficiency being due in part, no doubt, to the fact that the lime sticks it quite securely to the foliage, foli-age, so it is not readly washed off. Another desirable feature about this fungicide is that. Paris green can be used with it, thus saving one 'application, and that the lime also neutralizes any free arsenious acid in the Paris green and greatly lessens its caustic effect For all fungous diseases of plants, such as mildew, rust, rots and blights, in which either the spores, 01 the fungus itself, is exposed to its action. ' From Special Spraying Bulletin "When and what to Spray," published pub-lished by Michigan State Agricultural Agricul-tural College Exeperiment Station. Bordeaux Mixture. Copper Sulphate 4 pounds. Fresh Lime (unulaked) 3 pounds. Water 40 gallon. Place 6 gallons of water in a tub or barrel and hang in it 4 pounds of pulverized copper sulphate, in a burlap or other coarse sack. Slack the lime, adding water only ns fast as it takes it up, and pour together. Before using dilute to 40 gallons. Enough lime should ba added to neutralize the free acid as, if this is not done, it will injure the foliage. To test this, get five cents worth of ferro-cynide of potassium (yellow prussiate of potash) at a drug fctore, and place in a small bottle of water. Add a few drops of this solution to the Bordeaux, before it is diluted, and, if it turns brown,thelima is deficient and more lime should be added until the fer-rocyanide fer-rocyanide has no effect. The addition addi-tion of a slight excels of lime will generally bo dehiiabh. When much Bordeaux is used it is an excellent ex-cellent plan to make up a stock solution so-lution which can be diluted as used, proceeding i s follows: Dis- |
