The innovative sprayer for fine-drop treatment with oil preparations is the result of the needs reported by fruit growers, who every year struggle with the pressure of pests, restrictions on the use of plant protection products and low efficiency of treatments. Standard sprayers used in horticulture do not provide optimal parameters when applying oil treatments (number of drops per 1 cm2, mass application per 1 cm2 and degree of surface coverage). During the spraying, large losses of the substance used for the treatment are observed, too little coverage of the plant surface, poor spraying of the drops. The overriding goal of the planned operation is to obtain healthy plants and fruits characterized by high quality and taste values through the use of vegetable oils in plant protection. The choice of apple orchards for ecological research is justified by the situation prevailing in Polish fruit-growing and the problems of invasive pest species, i.e. Sanctuary scale, which producers face. In addition, the theme is in line with the prevailing trends in organic food. Unfortunately, the fruits available on the market are often of dubious quality due to overused or unauthorized use of insecticides. The implementation of specific objectives will contribute to a qualitative change of the product.
