Bee-killing neonicotinoids have been banned across Europe since 2013, but the UK government has just approved these deadly chemicals for emergency use
That part of the petition is untrue.
From my link (I know some posters don't like links):
EFSA has completed its assessments of emergency authorisations granted by 11 EU Member States for the use of neonicotinoid-based insecticides on sugar beet in 2020 and 2021.
The assessments cover 17 emergency authorisations for plant protection products containing clothianidin, imidacloprid, thiamethoxam and thiacloprid granted by Belgium, Croatia, Denmark, Finland, France, Germany, Lithuania, Poland, Romania, Slovakia and Spain.
In 2020 the European Commission asked EFSA to assess whether the emergency authorisations granted by the Member States were justified because there was a danger to crops “which cannot be contained by any other reasonable means”, in line with the EU Plant Protection Products Regulation.
EFSA has concluded that in all 17 cases the emergency authorisations were justified, either because no alternative products or methods – chemical or non-chemical – were available or because there was a risk that the pest could become resistant to available alternative products.
So the petition needs to be sent to the UK Government and to the European Commission too.
