This is true of both fruits and vegetablecrops.(Fig. 212). Spray Materials to Prevent Disease.—Nearly all of the plantdiseases are caused by fungous growth. A few, however, are from 303 304 PRINCIPLES OF SPRAYING bacteria attacks. The chief spray materials used to prevent dis-ease are Bordeaux mixture, lime-sulfur, ammoniacal carbonate ofcopper, and livers of sulfur. The first two mentioned are morepermanent and are not easily washed off by rains when once dry onthe plants. The other two materials are used in cases where it isnecessary to wash the fruit or other product before being eaten bypeople. They may be used to spray fruits that are nearly fungicide is copper sulfate used on the dormant form of. Fig. 212.—Spraying improves quality and increases yield.

Bordeaux mixture is made of three materials: copper sulfate,fresh lime and water. The standard formula is 4 pounds of coppersulfate, 4 pounds of lime, in 40 gallons of water. This is brieflyexpressed as 4-4-40. The 3-3-40 formula is sometimes used whereplants are tender, as on young tomato plants. Dissolve the copper sulfate in hot water or hang the crystals in a SPR
