THE USE OF BIOPREPARATIONS WITH BACTERIA AND FUNGI TO CONTROL DOWNY MILDEW (Plasmopara vitícola) AND REDUCE CHEMICAL TREATMENTS

Abstract

This paper reviews the possible biological control of grapevine downy mildew Plasmopara viticola. Often, when the climatic conditions are very favorable for the emergence and manifestation of the disease, the chemical treatment has a low efficiency, this phytopathogen producing significant damage, including as a result of the formation of resistant strains. A modern method of combating it is biological control using microorganisms bacteria and fungi which can inhibit through their presence directly or indirectly the growth and multiplication of the fungus, which we present in this paper.
