The Phytocontrol Laboratory analyses chlorothalonil and its 4 metabolites: Chlorothalonil 4-hydroxy, Chlorothalonil R471811, Chlorothalonil SA and Chlorothalonil SYN507900.<\/b><\/p>\n\n\n\n

In 2023, chlorothalonil received increased media attention due to concerns about its potential impact on human health and the environment.<\/p>\n\n\n\n

The ANSES Nancy Hydrology Laboratory, as the national reference laboratory for water intended for human consumption (EDCH), has undertaken a study covering the period 2020-2021. The aim of the study was to detect various emerging compounds in EDCH, including 157 pesticides and metabolites, 54 explosives residues and 1,4-dioxane.<\/p>\n\n\n\n

Focus on Chlorothalonil<\/h3>\n\n\n\n

Chlorothalonil is a fungicide widely used in agriculture to control various fungal diseases that affect crops. It is effective against a wide range of fungal pathogens that attack plants, including moulds, leaf spots and rots.<\/p>\n\n\n\n

Chlorothalonil has been banned in the EU since 2020. Once applied to crops, the active substance degrades in the form of several metabolites, including Chlorothalonil-R471811, Chlorothalonil 4-hydroxy, Chlorothalonil SYN507900 and Chlorothalonil SA.<\/p>\n\n\n\n

Furthermore, chlorothalonil is not very soluble in water, unlike its metabolite chlorothalonil R471811, which is very persistent in water. In its opinion of 26 January 2022, Reference No. “2021-SA-0020-b”, ANSES classified chlorothalonil R471811 in the category of relevant metabolites, which means that the molecule is suspected of presenting a risk to human health. As a reminder, the ruling of 11 January 2007 and its successive amendments set a quality limit of 0.1\u00b5g\/L for pesticides and relevant metabolites in EDCH.<\/p>\n\n\n\n

In addition to the Chlorothalonil analysis, Phytocontrol offers you a pack of 4 Chlorothalonil metabolites in response to the regulations in force for EDCH, using cutting-edge technology and very short lead times.<\/strong><\/p>\n\n\n\n
