Bees: Neonicotinoids

Caroline Johnson Excerpts

Wednesday 2nd February 2022 Westminster Hall

[Dr Caroline Johnson (Sleaford and North Hykeham) (Con)]

I think we can all agree on three things: that bees are very important and we should protect them; that we have all eaten something containing sugar in the last 24 hours; and that the Government have to consider competing risks and balance them carefully. Given the accepted importance of bees, the Government have developed the pollinator strategy. Their new environmental land management schemes for farmers will encourage the growing of areas in which bees can find safe habitat, increase the number of other areas for habitat for bees, increase public awareness of the needs of bees and increase the understanding of health and disease in bees, so that we can manage those more effectively. I welcome all of that.

We also have to consider the importance of sugar. Sugar production is responsible for 9,500 jobs in the UK, many in my constituency. I should at this stage mention that my husband is a farmer, although this is the first time in 45 years that no sugar will be grown on the farm. There are also 7,000 businesses in the sugar supply chain, and 3 million tonnes of sugar is consumed in the UK every year. I appreciate that the Government are investing in trying to ensure that we have pest-resistant varieties, so that no chemicals will be needed because virus yellows will not be able to attack the sugar beet, but these are not available yet. We had an awful time in 2020, just two years ago. I remember being called by many constituents to look around their fields and seeing whole fields of crops that had turned yellow because of virus yellows. Farmers had spent many months growing and tending to those crops, only to find them failing.

The Government have to look at the various risks and ask what the alternative is. If our sugar crop fails, what do we have to do? We could import sugar beet from Belgium, France, Denmark, Spain or one of the other 12 European countries where sugar beet is grown and where they also use neonics, often without the restrictions that the Government have proposed to impose. I heard Members mention the effect on net zero. Let us think about the alternative—importing sugar cane from overseas. What about the deforestation? Most sugar beet is not irrigated; it is just fed by the rain, but sugar cane, because of where it is grown, usually has to be irrigated. That is a 60% water use saving. What about the food miles? We know that sugar grown in the UK travels an average of 28 miles to the factory to be processed into sugar. It travels many thousands of miles, and is a much greater use of carbon dioxide, if imported for many miles across the world. When making environmental judgments, we cannot take the moral high ground and simply export the harm overseas, because we all live on the same planet, and I am sure we agree that we all need to protect it.

What are the farmers’ alternatives if neonics are banned? Either not to grow sugar and to import it, or to use alternative, legal pesticides, which may be broader-spectrum, and potentially more harmful.

[Virginia Crosbie (Ynys Môn) (Con)]

My hon. Friend is making an excellent speech that also mentions farmers. My constituency of Ynys Môn has a strong beekeeping community represented by the Anglesey Beekeepers Association. We have many local honey producers, including Anglesey Bees, Mêl Môn, Felin Honeybees run by Katie Hayward. Does my hon. Friend agree that our farmers are key and that any chemicals, including neonicotinoids, should be used correctly to protect the bee population?

[Dr Johnson]

Absolutely. We must remember that bees are very important to farmers, as my right hon. Friend the Member for Scarborough and Whitby (Sir Robert Goodwill) made clear. Farmers do not wish to use pesticides that they do not need. Equally, they do not wish to see their entire crop fail, nor do we want the alternative of importing crops from overseas, where worse pesticides might have been used.

The Government need to balance the risk, and I think they have done so very carefully. There needs to be a threshold for virus yellows predictions for the year. Indeed, there was a derogation last year, but the seed treatments were never used because the threshold of virus yellows disease was not reached. The application is a seed treatment, which means it is not sprayed on to a flowering crop, potentially landing on bees as they fly past. It is a treatment put on to the seeds, giving protection in the early growth phase. It is not permitted for flowering plants to be grown in that field for 32 months, thus providing additional protection for the crop.

On balance, it is important that we always take an evidence and science-based approach, looking at the potential risks and benefits. Science will ultimately resolve the problem by providing disease and pest-resistant varieties, but I am glad that in the meantime there has been a proportionate and pragmatic Government response.

[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.
