Bees feed on fermented pollen – i.e. bees need yeasts to assist with digestion of pollen – so fungicide would be expected to harm bees. This research links the presence of the fungicide chlorothalonil with the presence of a bee gut pathogen – Nosema bombi.

Chlorothalonil is a widely used fungicide in UK – especially in cereal crops.
