The assessments are crucial to understanding the threats the pesticides pose to animals, people and the environment.
Bayer and Syngenta criticised for secrecy after unpublished research obtained under freedom of information law linked high doses of their products to damage to the health of bee colonies
Unpublished field trials by pesticide manufacturers show their products cause serious harm to honeybees at high levels, leading to calls from senior scientists for the companies to end the secrecy which cloaks much of their research.
The research, conducted by Syngenta and Bayer on their neonicotinoid insecticides, were submitted to the US Environmental Protection Agency and obtained by Greenpeace after a freedom of information request.
