Monsanto's global weedkiller harms honeybees, research finds

Glyphosate - the most used pesticide ever - damages the good bacteria in honeybee guts, making them more prone to deadly infections

The world's most used weedkiller damages the beneficial bacteria in the guts of honeybees and makes them more prone to deadly infections, new research has found.

Previous studies have shown that pesticides such as neonicotinoids cause harm to bees, whose pollination is vital to about three-quarters of all food crops. Glyphosate, manufactured by Monsanto, targets an enzyme only found in plants and bacteria.
