PREVENTIVE AND CURATIVE MEASURES FOR BIOLOGICAL CONTROL OF THE PATHOGEN BOTRYTIS CINEREA IN EGGPLANT CULTIVATION IN GREENHOUSE

Abstract

Romanian agricultural research gives special importance to the development of technologies for the cultivation of vegetables grown in ecological agriculture. This paper presents the biological control of grey mould (Botrytis cinerea) pathogen on eggplant (Solanum melongena) cultivated in greenhouse, using the following products: Cavaler 600SL (microorganisms Bacillus pumillus and Bacillus subtilis) 0.3%, Amulet (microorganisms Bacillus thuringiensis, Bacillus subtilis, Bacillus megatherium) 40 l/ha, Zytron (citrus seed extract 20%) 0.15% and Mimoten (Mimosa tenuifolia 80% extract) 0.3%. The efficacy of biological products varied between 65.9% (Mimoten 3 l/ha) and 90,1% (Amulet 40 l/ha) in controlling this pathogen on leaves and lower efficacy on the fruits with values ranging between 34.3% (Mimoten 0.3%) and 62.2% (Amulet40 l/ha).
