The Influence of the Climatic Factors on the Main Vineyard Diseases When Organic Products Are Used in Feteasc Regal Variety

This paper presents the main results of a study undertaken during 2005 - 2007 in Blaj Center vineyard in whichwe followed the evolution of pathogens Plasmopara viticola, Uncinula Necator and Botryitis cinerea in wine grapevariety Feteasc Royal, in conjunction with climatic and treatment options without organic synthesis. There was a verybig influence of climatic conditions, in particular precipitation and relative air humidity that have an uneven distributionduring the growing season, which causes fungal diseases in each year of research. Research conducted during the threeexperimental years shows that the largest share in total degree assault had gray mold which met favorable conditions inthis area.
