Abstract: Abundant and diverse floral resources are needed for the preservation of pollinator populations and the services they provide to human societies. However, pollinators are negatively affected by several agricultural practices, among which pesticide use and ‘weed’ removal stand out. McDougall et al. (2021) published a paper titled ‘Managing orchard groundcover to reduce pollinator foraging post-bloom’, where they propose removing the within-field flowering ground vegetation after the mass flowering period of the crop ends, to reduce pesticide exposure. They consider this is a bee conservation strategy, after observing it reduces the abundance and diversity of pollinators within the crop. However, despite assuming this implied a realisation of an expected reduction in pesticide exposure, this was not quantified. Here, we give three main arguments against the proposal of the authors, that is, the need for providing accessible, sufficient, safe and seasonally-spread feeding resources to crop pollinators, the potential role of diverse floral resources in their pesticide tolerance, and the urgent need to reduce pesticide use and impact in agriculture.
