Pesticide Risk Assessment for Pollinators

David Fischer is Director of Environmental Toxicology and Risk Assessment at Bayer CropScience.Thomas Moriarty is a Team Leader in the United States Environmental Protection Agency's Pesticide Re-Evaluation Division.

“The debate concerning the effects of neonicotinoids on bees, though probably not the one about mobile phones, will no doubt continue for a long time so the publication of this excellent and comprehensive book is timely.”  (Chemistry & Industry, 26 January 2015)
