Neonicotinoids and other Pesticides

Duncan Baker Excerpts

Tuesday 5th March 2024 Westminster Hall

[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.

[Duncan Baker (North Norfolk) (Con)]

Pollinators, which are obviously the subject of the debate, are particularly important, but what about human health? Norfolk County Council is the first council in the country to ban glyphosate. That is an important move forward, and perhaps the hon. Lady will give her thoughts on that. More importantly, should we not be trying to find naturally produced, sustainable products that are not harmful to pollinators or human health and to repeat what has happened with Norfolk County Council and glyphosate? We should be rolling that out and putting all our scientific efforts into trying to find those products for the future.

[Jim Shannon (Strangford) (DUP)]

It is a real pleasure to serve under your chairship, Mr Henderson. I congratulate the hon. Member for City of Chester (Samantha Dixon) on setting the scene so very well on a subject that should really interest us all. If it does not, then there are questions to asked—that is the reason we are all here. It is a pleasure to see the shadow Minister, the hon. Member for Cambridge (Daniel Zeichner), who has a deep love of farming. It is an especial pleasure to see the Minister, who is always here whenever debates such as this are to be answered. I know that he, like me and others in this room today, understands the importance of the subject.

I declare an interest—not because I am a beekeeper, but because my neighbours down the road, Chris and Valentine Hodges, are. A couple of years ago, I let them put some of their beehives on to my land, because I wanted to see the natural environment that I live in enhanced. It quite clearly has been. They have what is called a black bee species, which is almost extinct; they are responsible for ensuring that it comes back. This is not just on my farm, but in the constituency across the whole of the Ards peninsula, up into North Down and as far over as Strangford lough. By the way, the honey is absolutely gorgeous. Every morning before I leave my house, I have two spoonfuls on my brown toast. Fibre is very important when getting to a certain age, so the honey gives me that wee bit of flavour and taste, and I thank the Lord for it. It is really special.

I am ever mindful of the responsibility that we hold to be good stewards of our environment, which I know is an obligation that our farmers honour in every sense. All the farmers I know want to do that; I know the Minister does that, and other people here do the very same. Many farmers see themselves not as landowners but as caretakers of the land for future generations, as the hon. Member for City of Chester said clearly in her introductory speech. The responsibility for producing food that is safe is of great importance. For that reason, many old-school farmers—I am probably one of them—have encouraged their children to attend agriculture college to get a basis of generational knowledge, while working hand in hand with modern techniques, and to be taught how to get the most out of the land and diversify where necessary. Our agriculture colleges are vital to the future food security of this nation, and that should also be noted today.

The complexity of grant applications and red tape has been somewhat reduced, but it is still a matter of concern to the farming community. The need for the Ulster Farmers’ Union—the sister organisation of the National Farmers Union in England—is very clear. The two work together and provide some of the best insurance rates possible; maybe I am a wee bit biased, because all my insurance is with the Ulster Farmers’ Union. That is why I looked to see what the NFU’s view was on this issue, knowing that it has hands-on knowledge and science at its fingertips.

I can understand that there are situations in which the use of these pesticides is important. Most recently, the Government approved an application from NFU Sugar and British Sugar for the emergency use of the seed treatment on sugar beet seed in 2024. That was a vital application, and we need to look at it and recognise why that decision was made and its implications. The authorisation was granted on the condition that the product will be used only if the threshold for virus lessons is reached. Michael Sly, the chair of the NFU Sugar board, said:

“The British sugar beet crop, which safeguards more than 9,500 jobs, continues to be threatened by Virus Yellows disease.”

That terrible disease can do all sorts of damage to the countryside and to bees in particular. He continued:

“In recent years the disease has caused crop losses of up to 80%.”

We cannot ignore that; those are the facts, figures and statistics. He went on to say:

“I am relieved that this has been recognised by Defra”—

particularly the Minister who is here in Westminster Hall today—

“in granting the derogation which will be invaluable if we see a return of severe pest pressure.

An independent, scientific threshold is used to forecast the severity of pest pressure on the British sugar beet crop and any seed treatment will only be used if this threshold is met.”

So there are conditions; this is not a wild abandonment of the process, which is very much controlled. DEFRA and British Sugar have it well under control. Mr Sly added:

“the industry will again deliver a comprehensive stewardship programme to ensure safe and responsible use of the treatment if the threshold is met.

Led by the British Beet Research Organisation, the homegrown sugar industry is working hard to find viable, long-term solutions to this disease.”

This process is about the long-term vision and how we find a cure or something that ensures that this disease does no more damage.

[Duncan Baker]

I am the first person to say that we need to look at insecticides and make them safer. However, I represent a constituency that produces a large amount of sugar beet, and this derogation is for a limited period and for a non-flowering plant in its first year, so pollinators will not be at risk from it. The fact that we are spraying the seeds of this plant actually mitigates a huge amount of risk. I think the public do not fully appreciate that absolutely key point.

[Jim Shannon]

I thank the hon. Gentleman for that very salient and helpful intervention, which put the facts on the record. He explains why and how these things have been done, the controls that are necessary and why these things are necessary, and I am sure nobody here will have any concerns about the way they have been done, how long they will last or their importance. As I said, Mr Sly concluded by saying that the homegrown sugar industry is working hard to find a viable long-term solution to the disease, but it is imperative that we recognise the necessity for that.

To conclude, that application shows the level of thought that must go into having an application approved by British Sugar. The use of these harsh chemicals is not the first solution; it is a final solution. For that reason, I believe that they should remain available, but they should always—always—be closely monitored. We owe a duty to our environment, but also to our food security. The balance between them is so delicate, but it can be struck; I believe in my heart that if there is a will, there is a way. I look to the Minister, as I always do, to ensure that we in this House are doing the best we can to put the garden back in the shape that it should be in.
