In the context of organic farming, the control of plant diseases is done by applying certain methods that, depending on the time and method of application, can be preventive and curative. Deposits are usually additional sources of infestation with diseases that begin in the orchard. This paper proposes laboratory cultures of pathogens such as Venturia inaequalis, Monilinia fructigena, Gloeosporium fructigenum, Botrytis cinerea, Penicilium expansum and Pezicula alba, in an attempt to limit the evolution of the diseases produced until the total cessation of evolution. After cultivation on MS culture medium enriched with vitamins and sucrose in a sterile manner, the pathogenic material is allowed to develop. After 6 days, treatments were made with colloidal silver and with a biopesticide solution based on essential oils made according to our own recipe. In both cases, the area of infection was considerably reduced, the best results being obtained, however, after the treatment with the LIVAL 1 Biopesticide.
