Pesticides: Thiamethoxam

Baroness Bennett of Manor Castle Excerpts

Thursday 20th January 2022 Lords Chamber

Asked by

[Baroness Bennett of Manor Castle]

To ask Her Majesty’s Government what assessment they have made of the potential negative impacts of their decision to permit the use of the pesticide thiamethoxam for sugar beet cultivation on (1) bee health, and (2) the spread of antimicrobial resistance; and what steps they will take to mitigate the concerns raised by their scientific advisors about the use of this pesticide.

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Lord Benyon) (Con)]

My Lords, the Government have given emergency authorisation for the use of thiamethoxam in 2022 to protect sugar beet from viruses. The environmental assessment identified potential risks to bees and the authorisation imposes strict restrictions to minimise these risks. In particular, the pesticide will be used only if, according to independent modelling, the predicted level of virus is at or above 19% of the national crop. No flowering crop may be planted within 32 months of sugar beet having been treated.

[Baroness Bennett of Manor Castle (GP)]

My Lords, I thank the Minister for his Answer. I have no doubt that other Peers will address the absolutely crucial issue of bees. This relates also to our second Question on food security.

In the light of the Lancet article yesterday which showed that, in 2019, 1.3 million people around the world died as a result of antimicrobial resistance, I will focus on the second part of my Question. It is, perhaps, the first time this has been mentioned in the House. Increasing numbers of studies, and increasing understanding, show that cross-resistance can develop. Bacteria exposed to pesticides can end up being resistant to drugs they have never even experienced. Will the Minister commit to going back to his department and speaking to officials to ensure that sufficient account is being taken of this when all pesticides are considered?

[Lord Benyon (Con)]

I, my department and others mind desperately about antimicrobial resistance. When I saw the wording of the Question, I looked into the matter in some detail. The neonicotinoid we are talking about is an insecticide that is not found to be causally related to antimicrobial resistance. I will look at the Lancet article about which the noble Baroness spoke and I will take her points back. The Government take AMR extremely seriously and we are coming forward with a number of different ideas to tackle this problem.
