Show TO MAKE BORDEAUX MIXTURE Copper Sulphate, Quicklime and Water Are Necessary Ingredients Mix and Apply at Once. The necessary Ingredients for making mak-ing bordeaux mixture are : Copper sulphate, sul-phate, 4 pounds ; quicklime, 4 pounds ; water to make 50 gallons. Prepare the copper sulphate by suspending It in a gunny sack just below be-low the surface of several gallons of water in a clean barrel. When the sulphate is dissolved, which requires three or four hours, remove the sack and stir into the barrel enough additional addi-tional water to make exactly 25 gallons gal-lons of the copper solution. Prepare the lime by slacking it slowly and thoroughly in a clean barrel, bar-rel, strain, and add enough additional water to make exactly 25 gallons of lime milk. Stir thoroughly. Pour the two ingredients together Into another barrel, or better, directly Icto the spray tank, if it will hold 50 gallons. It Is highly important to stir the mixture very thoroughly and to strain both ingredients before they are combined, as otherwise clogging of the spray nozzles might result. Use a copper cop-per or bronze wire strainer of 18 meshes to the inch. Do not put copper sulphate or bordeaux mixture Into tin or Iron vessels ; use only wood or copper cop-per containers. Mix the bordeaux as needed and apply at once. It is never as good after it has settled. |
