Dear Constituent,
Thank you for contacting me about the use of neonicotinoids.
I am aware that the Department for Environment, Food and Rural Affairs (Defra) has approved emergency temporary authorisation for the use of the neonicotinoid pesticide Cruiser SB, due to the risks of yellows viruses to the UK's sugar beet crop.
When making this decision, the potential risks, such as any possible environmental harm, must be balanced against the potential benefits in addressing the danger, such as protection against a pest. In making this judgement, the Farming Minister considered the advice from the Health and Safety Executive, the Expert Committee on Pesticides and Defra’s Chief Scientific Adviser.
Emerging sugar beet seedlings are vulnerable to predation from aphids that have the potential to spread beet yellows virus. This can severely affect sugar beet yield and quality. In 2020, around 25 per cent of the national sugar beet crop was lost, which resulted in a total loss of £67 million across an industry that is linked to nearly 10,000 jobs.
I am assured by my ministerial colleagues in Defra that there are strict conditions to the emergency authorisation of Cruiser SB. This includes only allowing for application if independent modelling predicts a virus incidence of 63 per cent or above. On 1 March 2023, the Rothamsted Virus Yellows forecast announced that the threshold has now been reached, with the forecast predicting a national Virus Yellow infection level of 67.51 per cent for 30 March 2023.
Finally, I am informed that as the threshold has been met and as such limited use is allowed, then further strict conditions will be applied to minimise risks to the environment. This includes a maximum number of seeds planted per hectare and restrictions on farmers planting flowering crops in the same field within 32 months of a treated sugar beet crop, which will allow time for the chemical to break down.
During a debate in Westminster Hall last month, the minister again indicated that “he decision to allow the limited and controlled use of neonicotinoids on a single crop has not been taken lightly and is based on robust scientific assessment” and further details are here: Bee-killing Pesticides - Hansard - UK Parliament
Thank you again for taking the time to contact me.
Sincerely,
Richard Fuller MP
