Sustainability Report FY 2021

RUFFINO | Sustainability Report FY 2021 Tenute Ruffino S.r.l on the front line in develo- ping research against vine disease Italy’s vineyards are increasingly harmed by esca, a disease caused by a group of fungi that colonize the lymphatic vessels and the wood, compromising the translocation of the water and nutrients from the roots to the upper part of the vine. Esca disease causes damage in terms of production, quality and revenue, which is why the Unione Italiana Vini, University of Florence, the Italian National Research Council, Perleuve and the app 4Grapes have joined forces to find a solution and increase knowledge about the di- sease through national monitoring, which aims to involve an increasing number of companies through the research titled “Study about vine wood disease in the main winemaking regions in Italy”. In FY 2021, the study was first structured with an online questionnaire: “Diffusion and econo- mic damage: the opinion of technicians” to un- derstand how widespread esca was, which vine varieties were affected the most, the extent of the financial damage and which agronomic practi- ces were adopted to prevent the disease. Later, monitoring got underway in the vineyard using the 4grapes app, which enables all vine disea- ses to be monitored and analyzed, in addition to carrying out other surveys and observations to verify the health of one’s vineyard in comparison with the national or regional average. Here are the surveys carried out in FY 2021, whi- ch show only a fairly reduced portion. On avera- ge, 4.25% of the total vines analyzed are affected by esca and the gravity of the symptoms (avera- ge 2.23%) found in the vineyard is currently not regarded as critical (the threshold for the critical level is 10%). The monitoring will always take place in the same vineyards and a overall view of the disease’s progression will be developed in the coming years, which will be useful in ma- king operational decisions (uprooting and re- planting, renewal) and planning the necessary investments.
