Neonicotinoids and other Pesticides

Sarah Dyke Excerpts

Tuesday 5th March 2024 Westminster Hall

[Samantha Dixon (City of Chester) (Lab)]

I beg to move,

That this House has considered the environmental impact of neonicotinoids and other pesticides.

It is a pleasure to serve under your chairmanship, Mr Henderson. I thank all Members who have joined this debate. I also thank everyone who has signed the many petitions linked to the debate, including a significant number of my constituents in Chester. It is clear that the concern about this issue is overwhelming. Before I start, I should say that I will do my best to refrain from any bee puns.

On 18 January this year, the Government approved emergency authorisation for use of the highly damaging neonicotinoid on sugar beet for the fourth year in a row, going against the advice of their own advisers and the concerns of campaigners and environmentalists across the country. That decision is yet again ill-judged and wrong. It directly contradicts our national and international obligations, such as the commitment to halt species loss by 2030 and the obligation under the global biodiversity framework to reduce the overall risk from pesticides by at least half.

Those decisions are being made against expert advice, waved through without a parliamentary vote and made on the basis that they are temporary and in the case of an emergency. Have we really had an emergency for four years in a row or is this just the Government’s way of nodding through harmful practice on a yearly basis?

[Sarah Dyke (Somerton and Frome) (LD)]

I congratulate the hon. Member on securing this important debate. I am sorry for intervening early, but I have to go to a meeting and wanted to make my point.

I am a beekeeper myself. I was recently speaking to the Somerset Beekeepers’ Association, which called the Government’s ongoing war on insects “unfathomable”. Does the hon. Member agree that we must have rigorous testing of chemicals before they are approved for agricultural use, and that the Government should introduce a clear qualitative target for significantly reducing the overall use of pesticides in agriculture?

[Samantha Dixon]

I agree with the hon. Lady and I thank her for the intervention.

Last night, I noted a BBC article entitled “Bee-harming neonicotinoid use ‘makes a mockery’ of ban”. There is no doubt that there is an issue with virus yellows, but we are facing a biodiversity emergency and lifting the ban is not the way forward. We have got to find another way. I support the calls made in the article by Richard Benwell, the chief executive of Wildlife and Countryside Link, for the Government to urgently deliver their long-awaited strategy on sustainable pesticide use.

Bees and other pollinators have for many years been facing an increasingly difficult task in the face of changing agricultural practice. That is a challenge in itself for our farming community, but it can also lead to a decrease in available forage and produce monoculture deserts for much of the year, making insect existence increasingly challenging. It is well known that neonicotinoid pesticides can be very harmful to a wide range of insects and invertebrates, including our beloved bees. They affect the nervous systems of bees and other insects, resulting in paralysis and eventually death. In fact, author and academic Professor Dave Goulson has warned that just one teaspoon of this type of chemical is enough to kill 1.25 billion honeybees. That is equivalent to four lorry loads.

Environmentalists, campaigners and local beekeepers have been in touch with me ahead of this debate to share their views and concerns on this topic, including the Wildlife Trust, our own Chester zoo, and Angharad, a local beekeeper who kindly alerted me to a report by the expert committee on pesticides that states:

“There is new evidence regarding the risk from neonicotinoids globally which adds to the weight of evidence of adverse impact on honeybee behaviour and demonstrated negative impacts on bee colonies”.

Bees play a crucial role in our food supply chain by pollinating crops, and their decline could have cascading effects on biodiversity and agricultural productivity. We should be protecting them, not putting them in harm’s way. Insect populations have suffered drastic declines in the UK. Recent evidence suggests that we have lost 50% or more of our insects since 1970 and that 41% of the Earth’s remaining five million insect species are threatened with extinction. Of course, other human factors and habitat loss are also to blame, but so is the widespread use of neonics. Given that a third of our food crops are pollinated by insects, we have a lot to lose.

The Government’s emergency authorisation allows the seed coating of sugar beet crops with neonics—a method of application that results in only 5% of the pesticide reaching the crop. The rest accumulates in the soil where it can be absorbed by the roots of wildflowers and hedgerow plants visited by bees, or it can leech into watercourses and affect the wildlife that lives there. If we thought sewage in our waterways was not enough, we are also adding harmful chemicals into the mix. Harmful neonics have been found in more than 10% of English rivers despite a widespread ban in 2018. In more than half the rivers where neonics were detected, they were at levels that pose a significant risk to wildlife. I back our farmers and am concerned that sugar beet farmers are experiencing a difficult time. However, lifting the ban is not the way forward. In fact, the Department for Environment, Food and Rural Affairs’ own economic analysis found that there was little impact of the beet yellows virus on sugar beet yield in untreated crops.

--- Later in debate ---

[Samantha Dixon]

I could not agree more with the hon. Gentleman. In fact, that underlines the importance of the strategy coming forward on the use of all pesticides. I thank him for his intervention.

We must find a science-led way forward that not only protects our bees and safeguards our future biodiversity and human health, but helps the farming sector by supporting initiatives that promote alternative, bee-friendly pesticides and sustainable farming methods. Despite the emergency authorisation being granted in 2022 and 2023, the proportion of farmers who decided against using neonics was 29% and 40% respectively. That shows that an increasing number of growers are trying to farm in a way that does not harm nature or rivers, yet there appears to be no support for those growers from the industry or Government.

The Government have instead focused on short-term solutions that will undermine the long-term sustainability of the farming sector and disadvantage those growers trying to do the best for nature. Emergency pesticide authorisation risks not only the floodgates opening for other harmful pesticide use, but slowing down crucial research on the alternatives. Without those alternatives, climate change will only lead to increased demand for neonics. The use of pesticides in the agricultural industry has become commonplace for many years, and there are good cases to support the use of targeted pesticides to help secure successful food production. However, some of those treatments are not being used in a targeted way and are affecting beneficial pollinators, as well as pest species.

[Sarah Dyke]

Scientists increasingly believe that there is no safe level of pesticides for humans to be exposed to. There is growing evidence that pesticides become more harmful when they are combined together—something known as the cocktail effect. I spoke to an arable farmer last summer, who told me he would never allow his children to eat bread made with his wheat. When I challenged him, he simply said, “Well, I know what’s gone into it, don’t I?” Does the hon. Member agree that the Government need to regulate, incentivise and support farmers to lead the transition away from pesticide use?

[Samantha Dixon]

I agree. The hon. Lady makes a very compelling case, which I hope the Minister is listening to.

The widespread use of the pesticides is not seeking to target known pest species but, as the hon. Lady has mentioned, being used as a blanket catch-all that preloads the crops with deadly chemicals that can transfer into the pollen and nectar, and into the food chain. We must look for positive alternatives, and not settle for short-term harmful solutions.

Will the Minister comment on the assessment the Government have made on the impact of their emergency authorisation of neonics for the last four years? Will he explain why the Government have ignored expert advice, which puts our vital pollinators under threat? Will he commit to any future decisions on this issue being put to a parliamentary vote? Finally, will he tell us all when the long-awaited strategy will be published?

I thank all Members who have joined today’s debate. I know we are all busy bees with packed diaries, and I hope the rest of the debate will create a real buzz about this issue—sorry, I really couldn’t help myself. On a serious note, nature has a critical role to play in both integrated pest management solutions and tackling climate change. It cannot do that if it is under attack from harmful pesticides such as neonicotinoids.
