During the efforts to slow down the killing of insects, plant protection products are permanently banned. But additives can also be problematic, as it says "20 minutes" with reference to a Chinese study.
Chinese researchers have exposed bees to three adjuvants: NMP, Silwet L-77 and Triton X-100. As expected, these substances had no adverse effects on insects. However, along with neonicotinoid (acetamipride) at the usual concentration, bee activity of bees is reduced. The result was the same in the field as in the laboratory.
The cocktail was also more harmful than acetamiprid itself. The combination with the Silwet L-77 had a particularly heavy impact.
So far, it has been assumed that a mixture of different substances (different plant protection products or other substances) has a different effect than the chemicals themselves. The study of cocktail effects, however, is in its infancy, given the sheer number of possible combinations.
The fact that there is a growing mix of different pesticides in bees concerns all parties involved – from farmers to beekeepers to research. What can farmers actually contribute to protecting bees in crop protection?

That bees are important and useful is well known and should not be stressed further. However, abstaining from pesticides is still not always possible, as experts and farmers agree. A leaflet from Agridee on this topic introduces measures for farmers.
Spraying preferably before or after flowering.
During flowering, treat only in the evening (after …
