Impact of a synthetic fungicide (fosetyl-Al and propamocarb-hydrochloride) and a Biopesticide (Clonostachys rosea) on soil bacterial, fungal, and protist communities
Science of the Total Environment, 2020Co-Authors: Bertrand Fournier, Sofia Pereira Dos Santos, Julia Gustavsen, Frédéric Lamy, Edward A. D. Mitchell, Gwenael Imfeld, Matteo Mota, Dorothea Noll, Chantal Planchamp, Thierry HegerAbstract:The use of synthetic pesticides in agriculture is increasingly debated. However, few studies have compared the impact of synthetic pesticides and alternative Biopesticides on non-target soil microorganisms playing a central role in soil functioning. We conducted a mesocosm experiment and used high-throughput amplicon sequencing to test the impact of a fungal Biopesticide and a synthetic fungicide on the diversity, the taxonomic and functional compositions, and co-occurrence patterns of soil bacterial, fungal and protist communities. Neither the synthetic pesticide nor the Biopesticide had a significant effect on microbial α-diversity. However, both types of pesticides decreased the complexity of the soil microbial network. The two pesticides had contrasting impacts on the composition of microbial communities and the identity of key taxa as revealed by microbial network analyses. The Biopesticide impacted keystone taxa that structured the soil microbial network. The synthetic pesticide modified biotic interactions favouring taxa that are less efficient at degrading organic compounds. This suggests that the Biopesticides and the synthetic pesticide have different impact on soil functioning. Altogether, our study shows that pest management products may have functionally significant impacts on the soil microbiome even if microbial α-diversity is unaffected. It also illustrates the potential of high-throughput sequencing analyses to improve the ecotoxicological risk assessment of pesticides on non-target soil microorganisms.

Biopesticides: State of the Art and Future Opportunities - Biopesticides: state of the art and future opportunities.
Journal of agricultural and food chemistry, 2014Co-Authors: James N. Seiber, Joel R. Coats, Stephen O. Duke, Aaron D. GrossAbstract:The use of Biopesticides and related alternative management products is increasing. New tools, including semiochemicals and plant-incorporated protectants (PIPs), as well as botanical and microbially derived chemicals, are playing an increasing role in pest management, along with plant and animal genetics, biological control, cultural methods, and newer synthetics. The goal of this Perspective is to highlight promising new Biopesticide research and development (R&D), based upon recently published work and that presented in the American Chemical Society (ACS) symposium "Biopesticides: State of the Art and Future Opportunities," as well as the authors' own perspectives. Although the focus is on Biopesticides, included in this Perspective is progress with products exhibiting similar characteristics, namely those naturally occurring or derived from natural products. These are target specific, of low toxicity to nontarget organisms, reduced in persistence in the environment, and potentially usable in organic agriculture. Progress is being made, illustrated by the number of Biopesticides and related products in the registration pipeline, yet major commercial opportunities exist for new bioherbicides and bionematicides, in part occasioned by the emergence of weeds resistant to glyphosate and the phase-out of methyl bromide. The emergence of entrepreneurial start-up companies, the U.S. Environmental Protection Agency (EPA) fast track for Biopesticides, and the availability of funding for registration-related R&D for biorational pesticides through the U.S. IR-4 program provide incentives for Biopesticide development, but an expanded effort is warranted both in the United States and worldwide to support this relatively nascent industry.
