Wine, what is mold and why it forces you to say goodbye to the (organic) harvest

Mold, which has halved the production of entire regions, but also flavescence, which contributes to the extinction of some varieties, and some insects “imported” from other continents, are redefining Italian wine production in an increasingly impressive way, especially the biological footprint.

It was a choice in line with our vision, which puts the protection of the environment and the health of those who drink at the forefront“, so one of the many Italian wine producers announces that there will be no “Year 2023“. Reason? PUSH they fall, which can cause serious damage to the vines and threaten the production capacity of the vineyards. But what is mold and why does it affect the harvest that follows ecological standards?

This bitter news comes from a Tuscan organic winery that produces fine Montepulciano wine, but the mold problem affects several vineyards, from north to south.

The blight that afflicts vineyards throughout Italy has strongly attacked ours too, forcing us to make the forced and coherent choice to abandon the harvest, as it is unthinkable to carry out more treatments than we have. we have set ourselves the goal of being a truly ecologically sustainable and organic company, say Podere Casanova.

What is mold

It goes o.a vine mycosis caused by a pathogen Plasmopara viticola. More precisely, it is a trophic disease that concerns – that is, nutrition caused by a parasite that takes energy resources from the host vine. PUSH they fall it attacks all green parts of the vine and causes greasy spots on the upper side of the leaf and white fluff on both the underside of the leaf and the shoots and bunches.

It is fungal diseasewhich can cause serious damage to the vines, endanger the production and economy of agricultural companies and wine cooperatives, especially those with an ecological focus.

During a regional hearing in recent months, Coldiretti Lazio called for financial support for farmers affected by the loss of production due to the disease, in order to avoid business closures and job losses.

In the approved ordinance in the last Council of Ministers they were taken just before the summer break urgent measures for wine productionwhich would allow agricultural holdings that have suffered damage as a result of downy mildew and that do not benefit from compensation from insurance contracts or mutual funds to access the foreseen interventions to support the recovery of economic and production activity.

But that’s really a drop in the bucket, because the year 2023 100% ecologically managed vineyards was practically impossible. In this case, fungicides based on copper and sulfur are actually allowed. Especially – when it comes to defending against they fall alternative vineyards are recommended to use copper in a maximum amount of 6 kg per hectare per year, which is a limitation given that copper can accumulate in the soil, with a consequent reduction in the microbial and biological activity of the soil and thus i .

The painful decision of several organic wineries to stop harvesting at least until 2023 depends on all of this.
