Oregano protects against fungal diseases in the vineyard

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 two Swiss researchers are currently doing are interesting. They discovered that by spraying essential oil of oregano on chasselas grapes […]

Wine producers are facing difficult choices today. Not least in what way they should manage the vineyard. Conventional, sustainable, organic or biodynamic? They have a variety of pesticides to choose from. More if they grow conventionally, less if they are organic. However, there are very different opinions about how dangerous these products are (e.g. glyphosate) […]

Corsican wine region bans glyphosate

The discussion about the future of glyphosate continues. It is very contested if glyphosate is dangerous or not at all dangerous (when properly used). In 2022, it will again be on the EU agenda, until then it is allowed. But France (at least the government, but not all farmers) wants to ban glyphosate before that. […]

Oil spray in the vineyard to fight weeds

During our spring wine tours we have visited the small and interesting Champagne house Philipponnat.

Lower copper limit for organic wine producers. Maybe.

Being an organic winegrower means that you are obliged to spray with copper to prevent certain fungal diseases rather than using synthetic pesticides. Copper is effective primarily against mildiou. As with all other pesticides the authorisation to use copper is renewed every ten years. This year the EU will evaluate copper and decide whether to […]

A future with herbicides replaced by thermal foam?

More and more herbicides are prohibited. What will happen to glyphosate and flumioxazin, two key ingredients in a variety of herbicides, is currently unclear. Many winemakers are preparing for a future without chemical weed removal. But there is no lack of new inventions. An Italian company will soon launch a new thermal weed control called […]

Bayer buys Monsanto?

To combat pests, diseases, and to remove weeds belong to the everyday tasks of a farmer and a wine grower. There is a lot of money – and controversy – in pesticides so therefore the announcement that the German company Bayer is probably buying the American company Monsanto has caused a lot of speculations. Bayer […]

Glyphosate, a herbicide to be allowed, or not?

The debate around glyphosate continues. The product is used as an herbicide, in for instance Roundup. It has been, since a while back, on EU’s list of unsafe products that maybe should be phased out. It is now time to renew the permit for its use (which is done every ten years for pesticides). This […]

South African rooibos plant used instead of sulphur

Rooibos is a South African plant that we have so far only been in contact with in the form of tea. Rooibos has a strong antioxidant capacity, preservative, like sulphur. Wine producers now realise that maybe this quality can be used for winemaking. The big producer KWV has recently launched a wine called Earth’s Essence […]
