BETTER FRUIT Page 2^ How to Mix Bordeaux Mixture Standard Fungicide May Easily Made Witli Attention to Certain Details Bordeaux mixture, the standard fun- gicide for use in controlling disease on plants, may be easily made by a little attention to a few important details. The standard mixture, known as the "4-4-50" formula, is composed of the following ingredients: Bluestone (cop- per sulphate), 4 pounds; lime (un- slaked), 4 pounds; water, 50 gallons. The method of making is as follows: Dissolve the bluestem by suspending in a sack in water, and dilute to 25 gallons. Slake the lime, being sure to use only the fresh stone, to an even paste with a small amount of water to start, and when slaked, add sufficient to make 25 gallons. Mix these dilute solutions by pouring together slowly into the spray tank or barrel, through a 20-mesh strainer made of brass wire. Stir well. In large operations it is best to prepare stock solutions of both blue- stone and lime. The bluestone may be dissolved at the rate of one pound per gallon of water. The lime may also be slaked at the same rate, one pound to the gallon, being careful to make up water lost by evaporation before using, if kei)t for any length of time. Stir the mixtures well before using to in- sure getting on
