Abstract

Abstract: Non-target organisms are globally exposed to herbicides. While many herbicides – for example, glyphosate – were initially considered safe, increasing evidence demonstrates that they have profound effects on ecosystem functions via altered microbial communities. We provide a comprehensive framework on how herbicide residues may modulate ecosystem-level outcomes via alteration of microbiomes. The changes in soil microbiome are likely to influence key nutrient cycling and plant–soil processes. Herbicide-altered microbiome affects plant and animal performance and can influence trophic interactions such as herbivory and pollination. These changes are expected to lead to ecosystem and even evolutionary consequences for both microbes and hosts. Tackling the threats caused by agrochemicals to ecosystem functions and services requires tools and solutions based on a comprehensive understanding of microbe-mediated risks. Highlights: Microbes have driven ecoevolutionary adaptations since the origin of life and maintain the welfare of ecosystems today. Global contamination with herbicides, initially considered safe for non-target taxa, is shown to influence soil, plant, and animal microbiomes. Changes in microbiomes can have unforeseen effects on organismal and ecosystem functioning and have evolutionary consequences. A comprehensive understanding of the risks associated with agrochemical-altered microbiomes is needed.
