Show Bordeaux Mixture May Be Reduced in Strength Bordeaux mixture may be greatly reduced In strength and cost without lessening its efficiency as a fungicide by reducing the copper sulphate content con-tent This has been proved in actual practice. In preparing bordeaux a recommended recommend-ed rule is to use three pounds of good hydrated lime for each pound of copper cop-per sulphate. A 2-6-50 bordeaux spray In the pink of the fruit bud of the apple, sprays of half that strength, or l-li-oO bordeaux, just after the petals fall and again in two and ten weeks thereafter, have given as good results In scab control as the so-called standard stand-ard 3-9-.V) mixture, and w-ith far less Injury to fruit and foliage. Even weaker mixtures than the l-3-.'.O gave satisfactory control of apple Scab and apple blotch. Success in the control of fungous disease depends more largely on timeliness time-liness and thoroughness in spraying than upon the strength of the materials mate-rials used. |
