Observations made in the departments of Gard and Vaucluse in southern France show a high level of symptoms of downy mildew, a severe fungal disease, on several supposedly fungus-resistant grape varieties, sometimes called piwi grapes.
A new study by INRAE, a French research institute, in collaboration with the universities of Bordeaux and Québec, shows the tolerance of different grapes to drought. Coping with dry weather is a grape characteristic that
Champagne Bollinger’s flagship Vieilles Vignes Françaises (VVF) is made in ever smaller quantities. The grapes come from vines planted franc de pied, a French expression for planted on its own roots. Thus, these vines are
There is a lot of talk about fungal diseases, which are a real problem for winegrowers (powdery mildew/oidium, downy mildew/mildiou and others). But other diseases in the vineyard are also serious. One is flavescence dorée
In several European wine regions, fungal diseases in the vineyard have been a major problem this summer. Severe attacks by, not least, downy mildew can be difficult to manage with only organic spraying (i.e. copper).
2023 was the smallest harvest in Australia in 23 years. The problem this season has mainly been various diseases in the vineyard. The Riverland in South Australia has been badly affected and a whopping 32%

Pests can be troublesome in the vineyard and now another one has been found in mainland Europe. Already in 2016, vines infected by the bacterium Xylella fastidiosa were discovered in Mallorca. Now it has shown
In the appellations of Bordeaux and Bordeaux Supérieur, and probably soon in the Haut-Médoc, they are allowed to plant certain non-traditional Bordeaux grapes varieties that are believed may possibly help the region cope with a

By using the new genetic technology CRISPR-CAS, Chilean scientists have produced a grape that is resistant to oidium, a fungal disease. The grape in question is Thompson seedless, a table grape, so not relevant in
Winegrowers all over France, yes, all over the world, organic as well as conventional, spray the vines with copper against the severe fungal disease downy mildew (mildiou). There are, regretfully, very few realistic alternatives to
Today, 45 different “resistant” grape varieties are permitted to be planted in France. And so far, they have been planted on 1,200 hectares. There is an interest among winegrowers to plant these grape varieties that
In the French wine magazine Vitisphere, we read about the five most significant challenges facing the winegrowers in the vineyard in 2022. These are not new challenges, but some have become more difficult. Mildiou and
A colleague in the industry that I spoke to the other day said when we discussed spraying the vineyards, “Can’t they just ban everything dangerous?” Yes, that sounds like a good idea, in theory. But
There is something called heroic viticulture. It is, for instance, vineyards on steep slopes, at high altitudes, on narrow terraces, on dry, windy islands. Here the wine world’s superheroes toil. The more difficult the terrain,
Essential oil from orange peel has a drying effect on the vine, it is desiccating. Therefore, many organic wine producers use this product to complement sulphur and copper in the fight against mildiou and oidium
Vines are also affected by viruses. The most difficult one in France since several decades back is court-noué, which is also found in other countries. In English, it is called grapevine fanleaf virus. It is

Can the solution to the problem of the dreaded fungal disease downy mildew (mildiou) be something as simple as oregano? It is a little early to answer yes to that question. But the experiments that
Walla Walla, a well-known wine region in Washington State, was believed to be exempt from the vine louse (phylloxera vastatrix). Therefore, the recent discovery of the louse that is so dangerous to the vines dealt
The vine is in many ways a robust plant that can withstand difficult conditions and drought. But it has weaknesses. One is that it is prone to fungal diseases. No vineyard can survive without spraying.
When we talk about countries with non-grafted vines, most people think of Chile, the only country in the world that is completely free from phylloxera, the small wine louse that infects the wine roots and
Four new white grape varieties have just been approved for use in Austrian Qualitätswein (quality wine) Three of these are so-called PIWIs, which is fungal resistant crossings. PIWI is a German abbreviation for Pilzwiderstandsfähig (literally
