Canton of Zurich: Up to 90 percent fewer grapes

The wet summer had a disastrous impact on the grape harvest. Conditions were ideal for mildew and other diseases and pests. In the canton of Zurich, the grape harvest was 50 percent smaller than usual. In some of the canton’s regions, as much as 90 percent of the harvest was lost. To protect their grapes, organic winegrowers had to rely on pesticides from conventional agriculture.

It was the wettest summer in decades. As the newspaper “Tages-Anzeiger” reported, winemakers are calling 2021 the worst year for wine in 20 years. Winegrowing regions throughout Switzerland have been affected. In the canton of Valais, yields are expected to drop by between 30 and 40 percent. In some place the situation has apparently been so dire that wineries have been the victim of grape thieves. In the Lake Geneva region, the harvest was only half its normal size. The canton of Zurich, too, has been hard-hit. According to the agency Fachstelle Rebbau, the grape harvest in Zurich was 50 percent smaller than usual. In some of the canton’s regions, as much as 90 percent has been lost.


Organic winegrowers also used conventional pesticides

Because of the wet conditions, mildew has been a particularly widespread problem in Swiss vineyards. This fungal disease has made life especially difficult for organic winegrowers. The “Tages-Anzeiger” reports that according to the wine commissioners, organic growers have had to rely more on pesticides that are normally approved only for use in conventional agriculture. As a result, some wine producers are likely to lose their “organic” label.

Organic farmers, too, need pesticides

It is often alleged that “organic farmers don’t need pesticides”.That is not true. To earn “Bio Suisse Bud” certification, however, production must comply with very strict regulations. Precise guidelines determine which agents may be used. The Research Institute of Organic Agriculture (FibL) publishes a list of permissible fertilizers, crop protection products and biocides.

Farms are only allowed to display the Bio Bud label if their entire operations, and not just some parts or certain crops, follow Bio Suisse guidelines. This leaves no room for flexibility. In bad years, when organic pesticides are not enough, farmers have no choice but to stand by and watch their crops die.


Organic rules increase food waste

This leads to food waste in the fields, which is not resource-efficient. All of the invested labor, energy, money and seeds are for nothing. The rigid rules for organic production spark discussions on a regular basis. Bio Suisse guidelines stipulate that medicinal products and vaccines must be free of genetic engineering. A few years ago, the president of Bio Suisse, Urs Brändli, came under pressure after almost all of Switzerland’s organic chickens received a genetically modified vaccine. This high-tech vaccine offers protection against a highly infectious virus. “We were faced with a very difficult dilemma. We had seen thousands of animals die. That’s why we made a clear decision in favor of animal welfare – and opted to use the vaccine,” Brändli told “Rundschau,” explaining why the vaccine had been granted temporary approval.

By refusing to use modern technologies, the organic sector is increasing food waste and impeding resource-efficient production – which is not the way to achieve a truly sustainable agricultural landscape.

Why trust in science is so important

It is essential that society has confidence in research. Only in this way can it realise its maximum potential and ultimately overcome social challenges such as climate change or a pandemic. But there are also critical voices: Some of the Swiss population has little or no trust in science. Four experts debated how research can gain people's trust at an «NZZ Live» panel discussion.

Crop protection products are in short supply - and soon the first vegetable varieties too

Vegetable producers are currently struggling. The reason for this is the lack of crop protection products . It is becoming increasingly difficult to bring saleable products onto the market. Some farmers are even reaching their limits to such an extent that they have had to stop growing certain vegetable varieties.

Pests increasingly threaten fruit, berry and grape harvests

Fruit, berry and wine growing is increasingly threatened by pests such as the Japanese beetle, the spotted wing drosophila and the Mediterranean fruit fly. Producers are sounding the alarm – but there is a lack of pesticides that can put an end to the pests.

Organic farmer calls for genome editing for fruit growing

The high number of plant protection treatments is a major challenge for organic farmers. One of them is apple grower Marco Messerli from Kirchdorf BE. He has had to treat susceptible apple varieties with organic pesticides a total of 48 times. Too much, he thinks, and is now calling for the authorisation of new breeding methods. Experts agree with him.
