Monitoring the evolution of the pathogenic agents in varieties grown in the Copou Wine Center, in the context of climate change

Abstract

In the present, the vine culture is dependent on phytosanitary treatment applied against the pathogenic agents whose evolution can cause significant crop damage. Performing rational treatments in closely linked with the vine growth phenophases and climatic conditions influences the development and degree of attack of pathogens. The present paper aims to present the results of monitoring the evolution of pathogens in nine genotypes grown in the Copou wine center during two different years in terms of climate, 2020 and 2021, under the influence of the application of treatment schemes meant to maintain a low level of intensity, frequency and degree of attack of each pathogen. The studied genotypes have been assessed with the OIV scores of resistance level between 5-9 for the downy mildew, powdery mildew and gray mold attack.
