Influence of extra-root application of macro-(calcium), micro-fertilizers (boron) and the domestically produced multifunctional chemical Finovital (biorational activator of sustainability) on storage results of apple fruit has been studied. Fitovital is a mineral microfertilizer (by its composition) destined for extra-root plant nutrition with the aim of increase in their yields irrespective of soil-climatic zone and for improvement of taste qualities and nutritive value of received products as well. Fitovital contains water soluble salts of biologically active microelements in optimum rates and is an ecologically pure means of influence on plants. The aim of the experimentation was to study possibility of decrease in complex of apples diseases at storage by using domestic means and extra-root mineral fertilizers in local agroecological conditions. The positive effect of the increase in multiplicity of extra-root fertilization (with calcium and boron) on storage indices was detected. Extra-root fertilization of fruit with Fitovital and mineral elements in the vegetation period increased the amount of standard fruit after the storage in comparison with the control variant. Fitovital application sustains considerable reduction in the natural loss of fruit weight in the process of long storage and almost totally preserves apples from bitter pit, fruit and penicilium rot
