Pesticides praying of sugar beet

I heard on the news that the government is allowing a temporary removal of the ban on spraying the neonicotinoid (I hope that is correct!) pesticide. This is to protect the sugar beet crop that suffers from some insect infestation that reduces the crop. This is the very destructive, all killing one that wipes out all bees and insects. Is sugar beet more important than killing off our fast declining bee population.? Is this one of the advantages we are told we will have as an outcome of leaving the EU as wedo not have to comply with their regulation? I am astonished, astounded and furious at this decision.
