Mission accomplished for the first webinar of the Eurocastanea network
Eurocastanea, the European chestnut network brought online nearly 70 operators from the chestnut sectors: producers, APOs and marketers from 8 countries. Participants from Austria, Spain, France, Greece, Italy, Portugal, Morocco and Chile connected to follow this mini conference on this season’s chestnut production and the impact of the covid-19 on consumption. Three main themes emerged : tree’s health, new plantations and the 2020 production figures.
The management of the gall wasp
European countries have all achieved a protocol for the organic management of the gall wasp (Dryocosmus kuriphilus) through the introduction of Torymus. This method is effective and allows a fairly good control of the pest who caused significant losses to past year’s production. For example, this solution made it possible for Italy to return to its full production potential. However, Spain, Portugal and the Limousin area in France are still showing yield losses, the populations of the pest and the auxiliary are not yet balanced.
The development of chestnut plantations
The European market faces a high demand in chestnut but the offer remains low. Still, efficient plantation dynamics are now set up in many European regions such as Portugal, the North of Spain and in France.
Production prospects 2020
Portugal estimates that its production will amount to 36.000 tonnes, with medium sizes and good quality. Its production is developing with the entry into the market of fruits from new orchards.
In France, there is a fairly good harvest in the south-east. It is weaker in the southwest.
The Italian harvest is estimated at 20 to 30% higher than that of 2019 in most regions. Italy should thus retrieve its full production potential.
The production forecast for Spain is around 28.000 tonnes, it will be in deficit due to losses linked to the gall wasp.
Finally, Austria is seeing its production increase, new rational orchards are gradually coming into production. But its harvested volumes have always been much lower than those of other EU producer countries.
Common issues
During the webinar, topics common to the 5 countries of the Eurocastanea network were highlighted. The first subject is the control of diseases (chestnut blight, fruit rots, root dieback) due to climate change, hot and dry summers and autumns.
Second important point, the establishment of a water management policy appeared to be essential for a viable production.
Finally, speakers from each country recognized that it is indispensable to stimulate the market and consumption, and to communicate, especially to young people.
This webinar humbly replaced The European Chestnut Days which should have taken place in New Aquitaine (Limousin) in September this year. This major annual meeting of producers, marketers, processors and researchers is postponed until September 2021.
