Neonicotinoids on Crops

Debate between Ben Howlett and Mike Wood

Monday 7th December 2015 Westminster Hall

[Ben Howlett]

I would not possibly speak on the Government’s behalf, but I hope the Minister will answer that question by explaining the criteria that will be under consideration.

The EU allows member states to authorise the usage of the banned neonics products to deal with emergency situations that are temporary, limited in scale and controlled, in order to address a danger that cannot be contained by any other reasonable means. The Government granted permission for their use on oilseed rape where the crops are in greatest risk of pest damage. The area that was granted permission, which extends across Suffolk, Cambridgeshire, Bedfordshire and Hertfordshire, represents just 5% of the UK oilseed rape crop area. The Government rejected two earlier applications that would have covered 79% of the crop area. I am pleased that the Government accepted the application only for a far smaller area, but I am still concerned about the potential impact of neonics on the bee population in that area.

Field studies have suggested that the levels of exposure experienced by bees in the wild are not sufficient to cause any negative consequences for the pollinators. The problem with relying on that assertion is that there have not been experiments of a significant scale to provide definitive evidence on which to base our approach to neonics. The usage currently authorised by the Government provides a good chance to ascertain on a bigger scale what their impact might be.

[Mike Wood (Dudley South) (Con)]

I thank my hon. Friend for giving way and join others in wishing you a happy birthday, Ms Vaz. Is my hon. Friend familiar with the study by the European Academies Science Advisory Council that shows that, even at sub-lethal doses, the impact of neonicotinoids on pollinators can be such that the reduced crop yields actually offset any benefits from using them as a pesticide in the first place?

[Ben Howlett]

Yes, I have seen that report, and I agree with my hon. Friend about its findings.

The Government have frequently and rightly stated that they will base their future policies on scientific evidence. They admirably said that decisions need to be ruled by science, but if they are committed to that, then proper data must be collected from the crop areas that have been granted permission to use neonics. Because neonics are absorbed so well by plants, residues are found on the pollen and nectar, which consequently affects pollinators. Evidence about the effect of such residues is crucial for future conservation work, so I encourage the Government to consider using approved plots to help to shape future decisions.

The high number of signatures on the petition shows how concerned the public are about the harm that neonics cause to bees and other pollinators. I urge the Government to gather more scientific evidence from the EU’s research and from sites that currently use the banned neonics. I also urge them to consider other types of neonics that are currently authorised but may have a detrimental effect. Since 1990, the UK has lost about 20 species of bees. We cannot afford to keep losing those crucial pollinators.
