MANAGEMENT OF BENEFICIAL MICROORGANISMS RESOURCES TO SUSTAINABLE AGRICULTURAL PRODUCTION

The sustainability and security of Romanian agricultural production is under threat from intensive production practices, global competition and climate change factors. Maintaining the sustainable production of land lies in striking a balance between socio-economic goals and responsible natural resource management. To rise to the challenge, an integrated approach making full use of all the major players involved - farmers, consumers, regulatory bodies and scientists - is necessary. Trichoderma pseudokoningii Td85 antagonistic fungus was isolated from wheat seeds, Baragan agricultural region. Td85 beneficial strain has the following properties: a wide spectrum of action towards pathogenic microbiological contaminants in cereal crops, due to complex activity expressed by antagonism and competition for food and space colonization. Td85 beneficial strain provide reducing development of primary inoculum that survive in the soil and on the plant debris, due to high capacity for colonization and degradation of plant substrates. Saccharomyces cerevisiae L30b yeast strain was isolated from grapes Chasselas D'ore variety, RDIPP Bucharest vineyard. Research of L30b beneficial yeast was sidelined on strawberry crop, focusing on biological control of Botrytis cinerea fungus. The efficacy of L30b formulations was assessed on Favette (early), Cardinal (middle) and Pandora (late ripening) variety, achieving a reduced disease incidence and severity of grey mould on fruit and providing high efficacy against the pathogen.
