. Better fruit. Fruit-culture. Page 18 BETTER FRUIT The Value of Spray Spreaders T*HE use of the spreader in the poison spray solution which has come to be looked upon recently by expert hort- iculturists as very important to the or- chardist is set forth in a valuable way to the fruit grower by Leroy Childs and A. L. Lovett in the crop pest report recently issued by the Oregon Agricul- tural College. In putting this phase of spraying before the orchardist these ex- perts say: "The use of a spreader in the poison spray solution accomplishes a number of desirable things. By increasing the wetting and covering power of the solution it permits a reduction in the amount of arsenic necessary for protec- tion. By permitting a more uniform covering over the surface and increas- ing the adhesiveness, it affords a bet- ter protection from worms. Through the increased wetting and covering pow- ers afforded, less solution is required to cover the trees and a tank of spray will go farther, finally allowing the sj^ray to dry a smooth, even covering over the surface, an inconspicuous cov- ering of the mature fruit is obtained. This does away with the blotchy, con- spicious poison coating so objectionable on the fruit when apples and pears are sent to eastern markets, particularly since there has developed a tendency to discriminate against the heavily sprayed Western fruit. "The investigation of possible spreaders and their economic value in improving the efficiency of the spray solution under commercial orchard spraying conditions has been under way for four years. Many of the problems in connecion with the investigation have not as yet been satisfactorily solved, but of the materials tested as spreaders for cheapness, availability, combatibility, efficiency and ease of preparation, casein, miscible oil, glue and proprietary soaps appear to be the most satisfactory. "The casein used in the preparation of the spreader is the commercial pow- dered or granulated case
