Wildflowers Give Bees a Dose of Pesticides

Posted by timothy on from the bzzt-pass-it-on dept.

JMarshall writes: Wildflowers growing near fields sown with pesticide-treated seeds can be reservoirs of bee-harming neonicotinoid compounds, according to new research. The study suggests bees get most of their exposure to these pesticides from wildflowers, rather than from the crops the pesticides are designed to protect. At the peak of flowering season, 97% of the pollen brought back to beehives tested in the UK came from wildflowers, not the canola crops they were growing alongside.

    I think that one lesson of this research is that since bees get their honey not just from the targeted crops it's generally worth to try and contain the pesticides better. That means taking in account wind, drop size, delivery method. In fact it could mean that the pesticides on the targeted crops are the least of your concerns. Which is interesting.
