Beekeepers weigh concerns about European foulbrood and fungicides and consider if the pollination fees are worth the potential for damage to their colonies. In some growing regions in Canada the government is helping boost rental fees because there aren’t enough colonies to meet demand.(1)
To provide answers for beekeepers over the years, Project Apis m. has funded several research projects with scientists studying the subject-beginning as long ago as 2008!(2)
