Overhauling the assessment of agrochemical-driven interferences with microbial communities for improved global ecosystem integrity

Recent studies have shown that various agrochemicals can substantially affect microbial communities;especially those that are associated with cultivated plants.Under certain circumstances,up to 50% of the naturally occurring microorganisms can be negatively affected by common agricultural practices such as seed coating with fungicide-based matrices.Nevertheless,the off-target effects of commonly applied agrochemicals are still understudied in terms of their interferences with microbial communities.At the same time,agrochemical inputs are steadily increasing due to the intensification of agriculture and the increasing pathogen pressure that is currently observed worldwide.In this article,we briefly reflect on the current knowledge related to pesticide interference with microbial communities and discuss negative implications for the plant holobiont as well as such that are spanning beyond local system borders.Cumulative effects of pesticide inputs that cause alterations in microbial functioning likely have unforeseen implications on geochemical cycles that should be addressed with a high priority in ongoing research.A holistic assessment of such implications will allow us to objectively select the most suitable means for food production under the scenario of a growing global population and aggravating climatic conditions.We present three hypothetical solutions that might facilitate a more sustainable and less damaging application of pesticides in the future.
