Bees: Neonicotinoids

Victoria Prentis Excerpts

Wednesday 2nd February 2022 Westminster Hall

[The Minister for Farming, Fisheries and Food (Victoria Prentis)]

Sir Roger, it is great pleasure to serve with you in the Chair, particularly as I think you would rather have been speaking in the debate. I congratulate the hon. Member for Plymouth, Sutton and Devonport (Luke Pollard) on securing the debate, and I thank Members for taking part in this really important discussion.

I should probably declare my interest. We have two hives of bees at home, and they are an integral part of our orchard management, particularly for my apple and pear crop.

Let me set out the problem. We all eat and enjoy sugar—some of us rather more than we should. It is important to remember that 63% of the sugar that the UK consumes is made from home-grown sugar beet, and we had an interesting debate on food security in this Chamber yesterday. Sugar beet seedlings are very vulnerable to aphid predation. The aphids spread the devastating virus yellows, which can seriously reduce both the quantity and quality of the crop. The disease is more widespread in certain years, particularly after mild winters.

As we have heard, neonics were previously used as a pesticide to tackle the problem. We banned their use outside in 2018, at the same time as the EU, because of a growing body of academic evidence that they could be damaging to bees and other pollinators. That affected my farm in respect of growing oil seed rape. We had grown the crop since 1974, but we no longer do so. In this, we are not alone, and the planted area of oil seed rape is not much more than half the level that it used to be before neonics were last used.

[Dr Johnson]

Will the Minister give way?

[Victoria Prentis]

I will not, as I have a great deal to get through.

Oil seed rape is significantly different from beet. As we all know, it is a beautiful flowering crop, and its pollen and nectar attract bees. Beet is harvested before flowering, so the crop itself does not pose a direct threat. Protecting bees and other pollinators is a priority for the Government through the pollinator strategy, and this is a way to bring farmers and researchers together in order to improve the status of pollinating insects.

The need to take action to protect sugar beet is not restricted to this country. Twelve beet-producing EU countries have granted emergency authorisations for neonics since 2018. Their authorisation conditions have been less stringent than ours—for example, none has applied a threshold to determine whether the product should be used. There is no doubt that if our crop suffered major damage because of aphid predation and we did not allow the use of a neonic in an emergency, we would have to import beet from countries where these products are used.

We have now had three years to grow the crops without neonics. In 2019, perhaps because of residual levels in the soil, and in 2021, after a cold winter, the virus threat was low. However, 2020 saw severe damage, with about a quarter of the national crop being lost, as we have heard. Some individual growers were even more severely affected. Imports were needed to enable British Sugar to honour its contracts. Partly because of that, a smaller crop was planted in 2021, with some growers understandably reluctant to take the risk.

Taking into account both the scientific evidence and the economic analysis, the decision was taken to grant exceptional temporary use of Cruiser this year. In order to mitigate the risk, conditions of the authorisation include a reduced application rate, as well as a prohibition on any flowering crop being planted in the same field within 32 months of a treated sugar beet crop. Our chief scientific adviser advised us on that mitigation.

There will be an initial threshold for use, meaning that the seed treatment will only be used if the predicted level of virus is above 19% of the national crop. If that threshold is not met, the treatment for the seed will not be used. That is exactly what happened in 2021. It will only be used in an emergency.

I would like to provide what I hope will be some reassurance to Members. The maximum amount of neonics that could be used on English crops, if the threshold is reached, will amount to 6% of what used to be used prior to 2018. In reaching our decision, we were informed by the advice of HSE, and the views of the UK expert committee on pesticides and DEFRA’s chief scientific adviser, who has been involved at every stage of the process. We also considered economic issues and were informed by analysis provided by DEFRA economists.

The scientific advice identified risks to pollinators, and the restrictions we have applied for are designed specifically by our chief scientific adviser to mitigate those risks. Some residual risk remains, but we judge that it is sufficiently low to be outweighed by the benefits to sugar beet production of using the product.

In taking this decision, we wanted to be as transparent as possible and give hon. Members, as well as members of the public, access to the information that informed the decision-making process.

[Daniel Zeichner]

The Minister says the risk is judged to be sufficiently low. Could she say a little more about how that judgment was arrived at?

[Victoria Prentis]

If I have time, I would be delighted to. I refer the hon. Gentleman to the full set of reasons given by the Secretary of State on gov.uk, because that gives the complete decision.

DEFRA agrees with HSE that it is not possible to completely rule out a degree of risk to bees from flowering plants in or near the field in the years after the neonic use. That is the concern. However, our chief scientific adviser suggests that the risks are reduced to a large extent by the 32-month ban on flowering crops.

The materials have been made publicly available. I was very keen to do that and to make sure that the decision was as transparent as possible. We have published several accompanying documents outlining the key elements involved in making the decision. There is nothing sneaky about the decision. The details are all available on gov.uk.

On the suggestion that we have a parliamentary vote on the issue, I am happy to look again at how the system works. We will be outlining our ideas about the new system in the national action plan, which will be published this summer. I politely say that there are at least 10 to 15 applications for emergency authorisations every year for different products. I see the hon. Member for Nottingham South (Lilian Greenwood) sitting over there—I do not know whether the Whips would be thrilled if we had to vote on each of those, nor perhaps would it be a good use of parliamentary time.

There is no doubt that this is an issue in which parliamentarians take an interest. That is right, and I am always happy to discuss these decisions with anybody who wants to. Please come and talk to me about the specifics of the decision or the science at any point.

Looking to the future, it is of course important that industry works hard on the development of alternative sustainable approaches to protect sugar beet from the viruses. Those include the development of new tolerant seed varieties, measures to improve crop hygiene and husbandry, and modern breeding techniques, such as gene editing. British Sugar and NFU Sugar attended a parliamentary event this week. I was able to talk to them about how they could interact better, telling us about the new products and ideas they can put in place to deal with the problem in future.

Ultimately, our food security relies on a healthy environment and thriving pollinators. Sustainable agriculture and supporting nature go hand in hand. In our agricultural transition, we are already incentivising farmers to do the right thing. This year, we are piloting a standard that will help farmers to transition away from the use of pesticides, and incentivise alternative ways to control pests.

This decision was not taken lightly, and is based on a robust scientific assessment. We will continue to work hard to support farmers and to protect and restore our vital pollinator populations.
