Developing and evaluating tools for assessing the impact of low-dose herbicide nicosulfuron on soil microbial diversity and functioning

Today's conventinal agriculture still relies on the general use of pesticides. Even thought this guarantees production capabilities it also causes environmental pollution having impact on non-targeted organisms. Agricultural practices have been recognized by "The European Soil Framework Directive" as a major threat for soil biodiversity. However, without taking into consideration. recent methodological advances in microbiology, pesticide regulation at EU level relying solely on simple C and N mineralization tè-sts•. ln order to cope with this ECOFUN­-MICROBIODIV project .aim to develop and evaluate tools to estimate the impact of herbicide nicosulfuron on the function and population dynamic…

ECOFUN-MICROBIODIV : an FP7 European project to estimate the ecotoxicological impact of low dose pesticide application in agriculture on soil functional microbial diversity

Soil is hosting a tremendous microbial diversity playing a key-role in a number of soil ecosystemic services including nutrient cycling and filtering. ln the European Soil Framework Directive pesticides are clearly marked as one of the major threats for soil biodiversity and functioning. ln orcier to guarantee minimum effects of pesticide application on soil microbes, pesticicleregistration at EU level (Regulation 2006/388) consiclers the toxicity of pesticides ontci non targefsoil microbes by relying on carbon- and nitrcigen-mineralization tests (OECO 216, 217). However tnese tests do not provicle a comprehensive assessment of pesticides onto soil microbes.-ECOFUN-MICROBIODIV was a project…

Towards the identification and quantification of candidate metabolites of tebuconazole fungicide

International audience; Tebuconazole belongs to the family of triazole fungicides, used for crop protection and human health applications. In the environment, the dissipation of the parent molecule leads to the formation of metabolites that are of unknown identity or toxicity. In order to identify and determine the putative identity of those metabolites and their po- tential toxicity, a quadrupole time-of-flight (Q-TOF) approach is often used. Q-SAR approaches help to predict their toxicity by comparing them to a known database of molecules with known properties. All together the information on the candidate by-products may help to select relevant sub-set of metabolites for further quantifi…
