The Greek cross-visit under the AdvisoryNetPEST project took place on 11–12 September in the Korinthos region, organized by GAIA EPICHEIREIN, with advisors from France, Spain, and Croatia joining the event.
Participants had the opportunity to visit the vineyards of Mr. Spiros Karachalios, a member of PEGASUS AGRIFOOD COOP – 7Grapes. His farm, located in Velina, in the broader area of Kiato, at relatively high altitude, extends over 2 hectares and is dedicated to Crimson Seedless table grapes. The vineyard is established on acidic red soils (pH 5.5) with calcium deficiency, under predominantly dry climatic conditions, yet faces challenges from Esca infections and sporadic extreme weather such as hailstorms and sudden drops in temperature.
Together with the cooperative’s agronomist, Mr. Thanos Dritsopoulos, Mr. Karachalios presented the cultivation process of Crimson grapes and the challenges encountered. Special emphasis was given to the use of biostimulants, which strengthen vine defense mechanisms, improve resilience to abiotic stress, and enhance nutrient uptake. This approach reduces reliance on chemical plant protection products while supporting plant vigor, berry uniformity, and overall fruit quality. The farmer confirmed noticeable improvements in vine resilience, berry color, fruit size, and commercial value, underlining his commitment to continuing the use of biostimulants. This sparked strong interest among participants, leading to ongoing discussions on the challenges faced in viticulture and the ways in which biostimulants can help overcome them.
The cross visit also included a visit to another vineyard of the cooperative with larger Crimson grape production, local sightseeing in the Korinthos area, and a final stop at the PEGASUS Agricooperative shop, where participants not only received an overview of the regional agricultural sector and insights into how this Novel Approach could be implemented, but also had the opportunity to vividly discuss its application and actively exchange knowledge and experiences.
