Emergency use of a neonicotinoid: unravelling the complexities behind the UK approval
On Friday 8th January, the UK government decided to allow the use of a neonicotinoid-based pesticide, thiamethoxam in emergencies.

When medicine feeds the problem: Are pesticides feeding crop pests?
SPRINT recently attended a fascinating talk at the Oxford Real Farming Conference. Researchers from the University of Edinburgh shared their findings surrounding why pesticides may, paradoxically, benefit crop pests. The research was born from the work by a French agronomist, Francis Chaboussou.

Banned substances continue to enter the market
18 December 2020 - Trouw: Interview Professor Annemarie van Wezel
From the North Pole to Mount Everest, chemicals can be found everywhere. “Thanks to our sensitive measuring methods, we always measure something, even if it is very little, you come across those substances everywhere because we use them all,” says Annemarie van Wezel, professor of environmental ecology and director of the Institute for Biodiversity and Ecosystem Dynamics ( IBED) from the University of Amsterdam. "We would love to go back to Adam and Eve, but we can't." Yet she is hopeful. A turnaround is feasible, although this will not be easy.
“Chemicals have brought us a lot, in agriculture, fire safety and the shelf life of materials and food. Ultimately, we must move towards less dependence and better restriction to essential use. But you have to look at that as a whole, not per substance. Because if you prohibit one substance, another that looks a lot like it, will replace it. ”
That makes it so difficult to prevent the spread of toxins, explains Van Wezel. “Compared to biocides, which are now widely used because of the corona pandemic, pesticides are receiving a lot of attention. Upon approval, we assess one product, which may be used in one crop. The problem is that the same substance can also be used in a different crop, end up in a different place or be used in a completely different context. But we don't look at that.”
Violette Geissen's SPRINT project may be able to change the European standards for the approval of chemical substances, Van Wezel thinks. For the authorization of one substance, the accumulation effect of several chemical substances is not considered. Geissen is looking at that cocktail effect. Furthermore, now it is not examined whether a substance is necessary, only what it does.
