The vote in the European Commission is a major extension of existing restrictions which have been in place since 2013.
Under the new ruling, three neonicotinoids - clothianidin, imidacloprid and thiamethoxam will be banned.
CLA Chief Land Use Policy Adviser Susan Twining said: “This is another blow to farmers at a time of significant uncertainty. Removing yet another tool from farmers which helps them control pests and disease will negatively impact their ability to farm efficiently and profitably, as we develop a post-Brexit strategy for agriculture.
“It is vital that regulatory decisions on crop protection products follow a science-based approach and we respect the decision of the regulators on this matter. It is however, incumbent on ministers and officials in the EU and the UK to think about the real world business impacts of these decisions, and work with us to provide the necessary support for farmers who need to find ways to combat pests, control costs and produce food efficiently.
"Above all we will be seeking reassurances from the Secretary of State that any restrictions will be enforced against all imports through Brexit and beyond.”
