«The fear of genetically modified plants is unwarranted»
Genetically modified plants have garnered a negative reputation, but with new methods, they can hardly be distinguished from conventionally bred plants, as Anke Fossgreen argues in the 'Tages-Anzeiger.'

The umbrella organization of organic agriculture, Bio Suisse, unanimously decided at its delegates' meeting on Tuesday to continue to refrain from using genetic engineering. The result is not surprising, but disappointing. It demonstrates that organic farmers are disregarding the advancements made in modern breeding research and perpetuating the negative perception of genetically modified food.
Ironically, it is precisely future genetically modified plants that offer possibilities that are important for organic farming as well. Modified plants can, for example, be resistant to diseases, reducing the need for pesticides. They can also be more durable, thereby reducing food waste, or they can withstand drought, which is crucial in the face of climate change.
However, why do many consumers refuse to eat genetically modified plants or animals fed with such plants? These plants, such as wheat, maize, and soybeans, are viewed with suspicion because their genetic makeup has been altered in the laboratory. Yet the fear of 'foreign genes' is unfounded. When we consume an apple, we ingest the fruit's genes; when we eat bread, we consume the grain's genes, and when we have a schnitzel, we consume the genes of a pig. Does this make us sick or alter us in any way? No. During the digestive process, our bodies break down not only proteins, carbohydrates, and fats but also foreign genetic material, utilizing it to sustain ourselves.
The discussion is no longer about the modified plant but the process by which it is produced.
Furthermore, genetic engineering has made significant strides. Today's genetically engineered plants are virtually indistinguishable from conventional breeds. This is achieved through genome editing techniques like the Crispr/CAS method, where the genetic material is slightly modified and optimized, akin to using a scalpel.
Those who previously felt uneasy about consuming genetically modified plants due to their perceived difference from conventionally bred plants no longer have a valid argument. Therefore, the discussion is no longer about the modified plant itself but rather the process by which it is produced.
As a reminder, since 1964, genetic modifications have been introduced into the genome of plants in Europe and elsewhere using methods that may sound alarming. Plants were bombarded with radioactive substances in fields and gardens, and now in laboratories. According to the International Atomic Energy Agency, more than 3300 plant varieties have been created through this so-called mutagenesis and have been approved in 70 countries. Some of these varieties are still used and consumed today, including many types of grain, rice, and citrus fruits, such as red grapefruit, which is also sold as an organic product.
In comparison, modern genetic engineering techniques are remarkably gentle and elegant.
While this may initially sound concerning, these plant varieties are not inherently radioactive simply because radiation was used in their production. Similarly, new plant varieties created through mutagenesis are not chemically poisoned, as the mutagenesis process can also be triggered by chemicals. These methods, perceived as 'natural' breeding, are employed to create new varieties.
In comparison, the methods currently discussed to enhance the properties of plants through modern genome editing techniques are remarkably gentle and elegant.
Furthermore, it is worth noting that the taste and nutrient content of plants can also be specifically optimized through these methods. Let us embrace the opportunity to experience these new varieties.

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.
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.
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.
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.
