Climate change more evident in recent years has been cause changes in life cycle of pathogens and pests, as well as has been increase aggression attack on vineyards. In this sense, in 2020-2021 period was followed the behavior of some vine varieties for table grapes newly created at SCDVV Iași, 'Mara’, ʻPaula’ and ʻAromat de Iași’ to the attack of the main pathogens (Plasmopara viticola, Uncinula necator, Botrytis cinerea) and pests (Lobesia botrana, Calepitrimerus vitis and Colomerus vitis). The observation of intensity and frequency on the leaves and grape attack highlight a different behaviour of the studied varieties. The results of the study confirm that the temperature and rainfall from the vegetation period influenced the pathogens attack and pests occur, attack degree and the economic damage threshold, as well as the quantitative and qualitative level of grape production. Also, varieties resistance in specific climatic conditions of the analyzed period under the application of anticryptogamic treatments was appreciated with notes on the OIV scale from 7-9.
