Question 32185 — dangerous products

Summary

Mr. Hugues Renson alerts the Minister of Ecological Transition to the use of succinate dehydrogenase inhibitors (SDHI) in pesticides. These fungicides spread on nearly 80% of wheat surfaces, on barley, on fruit trees, on tomatoes or on potatoes serve to destroy fungi by an enzymatic mechanism of action which causes cellular asphyxiation. However, these molecules also attack to populations of earthworms, nematodes, insects and aquatic fauna, creating inevitable breaks in food chains. Additionally, these fungicides target SDH, a molecule essential for cell respiration, which can pose risks to human health. According to Paule Bénit, research engineer, Inserm, and Pierre Rustin, research director, CNRS, these pesticides contribute to the loss of biodiversity and they call for the urgent application of the precautionary principle and the questioning of the use of SDHIs. Alerted for three years, ANSES is slow to react and the report requested from Inserm since 2018 has still not been published. Thus, 450 researchers called in January 2020 for an end to the use of these molecules in an open environment, while deploring a denial of scientific data. He asks him what measures the The government intends to take steps to accelerate the process of evaluating SDHIs and whether it intends to request an end to the use of SDHIs in open environments.
