Show DORMANT SPRAY IS URGED FOR SCALE Spraying orchards for the control of scale Insects, especially the San Jose scale, should be done during the dormant season. This means any time after the leaves drop in the autumn until the buds open In the spring. Usually this work is done In the spring, says the Indiana Farmers' Guide. It is reported that San Jose scale is increasing, principally because be-cause control measures have either been neglected or the weather conditions con-ditions have been unfavorable In the spring of the year for proper spraying. spray-ing. Spraying to be effective must be thoroughly done. The entire surface of the tree or shrub must be completely com-pletely covered with the spray material, mate-rial, to the case of trees It may be 1 necessary to apply the spray when the wind Is In one direction, then go over the trees again when the wind is In opposite direction, so no portion of the tree may be missed. A few spots not reached by the spray may harbor some of the scale Insects and from these colonies the entire orchard may be reinfested before the next winter. The spray materials used for scale insects are lime-sulphur and mlscible oils. Both are effective and both have their advantages and disadvantages. Some orchardists prefer one and some the other. Whichever, material Is used, it must be remembered that proper equipment Is essential If a good job is to be done. A barrel sprayer is the smallest nraetieal-sized eouln- ment for the farm orchard. It should have at least 35 feet of hose with a 10-foot rod and a 45-degree nozzle. For large orchards a larger power pressure should be used. Not only the dormant spray, but the applications made after the growing season begins to control other Insect pests and fungous diseases are Important. Impor-tant. Fruit from trees which have been thoroughly sprayed keeps better because It Is clean and healthy and It Is disinfected by the covering of spray. |
