Does chlorothalonil kill bees?
Chlorothalonil has been linked to stunted colony growth in bumblebees and an increased vulnerability to Nosema, a fatal gut infection in bumblebees and honeybees. While half of crop pollination work is done by commercially managed honeybees in the U.S., the other half is done by bumblebees and wild bees.
