Effect of succinate dehydrogenase inhibitor (SDHI) fungicides on public health

27.1.2020

Question for written answer E-000445/2020
to the Commission
Rule 138
Eric Andrieu (S&D)

Since the 2000s, in an effort to tackle problems with moulds and fungi, use of succinate dehydrogenase inhibitor (SDHI) fungicides on vines, fields of rape and sports fields has grown exponentially.

However, recent scientific studies have shown that this pesticide family acts by blocking a cellular-respiration enzyme known as succinate dehydrogenase (SDH). To varying degrees, they are also capable of blocking SDH activity in mould, earthworms, bees and human cells. These studies confirm that SDHIs are extremely dangerous because they can speed up a range of human illnesses which may be caused by cells’ respiration being blocked.

In the light of the above, what action is the Commission taking to apply the precautionary principle at EU level? For example, authorisation of boscalid, part of the SDHI family, runs out on 31 July 2020 (following two administrative extensions). Will the Commission ask for that authorisation to be renewed?

What specific plans does the Commission have to limit the risk of a health disaster resulting from the use of any of the SDHI fungicides in Europe?
