Show CARELESS SPRAYING IS NOT EFFECTIVE Every Part of the Surface ol Tree Should Be Covered ,With a Fine Liquid Mist. (By C. W. RAPP, Department of Horticulture, Horti-culture, Oklahoma A. & M. College, Stillwater.) Spraying, in ordinary language, means covering the plants treated. Every part of the surface should be covered with a fine mist. Spraying a little liquid spray into the tree to cover about half of the surface is not spraying, but, unfortunately, many folks think that it is. When you spray, cover the tree or don't spray at all. A single un-sprayed un-sprayed part of the tree, foliage or fruit leaves "a. door for the entrance of disease or provides food for Insects. Once started on a tree, these pests will usually manage to develop. In a short time much of the spray may be washed off by rains, and the results will be almost the same as if no spraying had been done. If you have half sprayed your trees instead of covering cov-ering them with a fine mist, blame yourself if little good results. Spray is effective only when applied In the right way. |
