It is therefore appropriate to target the parent molecule when establishing the list, without specifying the enantiomer (e.g. metolachlor instead of S-metolachlor).<\/p>\n\n<p class=\"wp-block-paragraph\">In conclusion to this instruction, the DGS states that, based on feedback from certain ARS, <strong>a list of 200 to 250 molecules is a satisfactory target<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">Once the methodology has been implemented, the list can be updated regularly in light of new data.<\/p>\n\n<p class=\"wp-block-paragraph\">Phytocontrol holds the national approval from the Ministry of Health for carrying out sampling and analyses for the sanitary control of water. We offer testing for a wide range of pesticides and metabolites to meet the needs specific to your region\/department.<\/p>\n\n<p class=\"wp-block-paragraph\">You can find the details of our accreditations in <a href=\"https:\/\/dev.phytocontrol.com\/en\/about-us\/our-accreditations-2\/\">our COFRAC technical annex No. 1-6066<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">Need technical, regulatory or pricing information?
