"We found that honeybees that had been fed with solution containing 10 mg l−1 GLY spent more time performing homeward flights than control bees or bees treated with lower concentrations. They also performed more indirect homing flights. Moreover, the proportion of direct homeward flights performed after a second release from the same site increased in control bees but not in treated bees. These results suggest that, in honeybees, exposure to levels of GLY commonly found in agricultural settings impairs the cognitive capacities needed to retrieve and integrate spatial information for a successful return to the hive. "

Glyphosate is also not allowed in organic produce. Because of allegedly inappropriate involvement of pesticide manufacturers in scientific reviews, glyphosate has also only been approved for five years in the EU (2017).

> And if you really go pesticide free, you start to have more insect damage in crops

There is an organic solution to insect damage and that is predators. I know some green houses that is run here uses sterile large insects that targets crop damaging insects, after which they are just washed off the plants. 100% toxin free and naturally you could balance that to get rid of molds as well. Costly but very effective.
