“…corresponding to the standard EN 17033 for the European Union), authorized in organic farming.β-triketone herbicides are derived from leptospermone, a natural phytotoxin produced by the Californian bottlebrush plant Callistemon citrinus (Mitchell et al 2001 ). These plant protection products (PPPs) were qualified as “eco-friendly” because of their efficiency at low agronomical doses: 350 g.ha −1 for sulcotrione and 150 g.ha −1 for mesotrione as compared to 1 kg.ha −1 for atrazine (Duke et al 2010 , Sidhardhan et al 2012 ). However, this “eco-friendly” reputation might be questioned, as these molecules target the 4-HydroxyPhenylPyruvate Dioxygenase (4-HPPD), an enzyme retrieved in plants but also in other organisms, such as mammals or soil bacteria, hence possibly having an effect on non-target organisms (Thiour-Mauprivez et al 2020a ).…”

Alternative farming systems have developed since the beginning of industrial agriculture. Organic, biodynamic, conservation farming, agroecology and permaculture, all share a grounding in ecological concepts and a belief that farmers should work with nature rather than damage it. As ecology-based agricultures rely greatly on soil organisms to perform the functions necessary for agricultural production, it is thus important to evaluate the performance of these systems through the lens of soil organisms, especially soil microbes. They provide numerous services to plants, including growth promotion, nutrient supply, tolerance to environmental stresses and protection against pathogens. An overwhelming majority of studies confirm that ecology-based agricultures are beneficial for soil microorganisms. However, three practices were identified as posing potential ecotoxicological risks: the recycling of organic waste products, plastic mulching, and pest and disease management with biopesticides. The two first because they can be a source of contaminants; the third because of potential impacts on non-target microorganisms. Consequently, the development strategies to allow a safe recycling of the increasingly growing organic matter stocks produced in cities and factories, and the assessment of the ecotoxicological impact of biopesticides on non-target soil microorganisms, represent two challenges that ecology-based agricultural systems will have to face in the future.
