Show CONTOL LEAF CURL AND SAN JOSE SCALE Lime-Sulphur Spray Is Recommended Recom-mended for Work in Spring Kill Fungus Spores. According to obcorvations made by the New Jersey station, peach leaf curl can readily be controlled by a thorough application of concentrated lime-sulphur before the buds swe.l in the spring. Bordeaux mixture, applied early in the spring before the buds start, also will control leaf-curl, but the lime-and-sulphur mixture is advisable advis-able because it will control San .lose scale as well. In using lime-sulphur it is ess.-titial t i use a solution that has been properly proper-ly prepared and diluted with water to a strength of not less than 1.03 specific gravity. The spray material should then be thoroughly applied so thai, every ev-ery bud and small twig receives its coating. Any portion of the tree that Is not covered with the spray material is likely to become infected. The object ob-ject of the early spring application is to kill the spores of the leaf-curl fungus before they germinate. In other oth-er words, spraying for leaf-curl must be preventive as no cure is possible after the disease is established. |
