Soil microbial community fragmentation reveals indirect effects of fungicide exposure mediated by biotic interactions between microorganisms

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 470, P. 134231 - 134231

Published: April 6, 2024

Fungicides are used worldwide to improve crop yields, but they can affect non-target soil microorganisms which essential for ecosystem functioning. Microorganisms form complex communities characterized by a myriad of interspecies interactions, yet it remains unclear what extent indirectly affected fungicides through biotic interactions with sensitive taxa. To quantify such indirect effects, we fragmented microbial community filtration alter and compared the effect fungicide hymexazol between fractions in microcosms. We postulated that OTUs would exhibit different response across communities. found primarily bacterial fungal were responsible more than 75% shifts relative abundance dominant after exposure an agronomic dose hymexazol. However, these effects decreased when doses increased. Our results also suggest N-cycling processes as ammonia oxidation be impacted application. This work sheds light on impact underscores need higher-tier risk assessment. ENVIRONMENTAL IMPLICATION: In this study, novel approach based fragmentation determine application could fungi bacteria interactions. assess off-target microorganisms, selected hymexazol, is control variety plant pathogens, exposed arable recommended field rate, well higher rates. findings show at least hymexazol-impacted affected, therefore emphasizing importance tiered

Abstract The Organisation of Economic Co-operation and Development (OECD) 216 nitrogen transformation test is used to understand the impacts plant protection products (PPPs) on soil microbiome. However, there significant interest in developing European PPP risk assessment include new technologies such as amplicon sequencing assess microbial community composition diversity. We have little understanding how generate endpoints from data sets, their robustness, whether they provide an appropriate level Our study addresses this key knowledge gap. conducted a dose-response OECD with two chemicals, nitrapyrin streptomycin, calculated traditional functional endpoints, accordance guideline, techniques range based bacterial diversity, richness, dissimilarity control, species sensitivity distributions, threshold indicator analysis. show it possible sets; however, these varied significantly calculation method, up 101-fold difference between least most sensitive endpoints. Additionally, relative compared currently metrics was compound dependent, many endpoint methods unable detect microbiome at concentrations deemed ecotoxicologically relevant by 216. shows ecotoxicology did not perform consistently reliably when considering both streptomycin treatments cases enhanced degree over assessments already integrated into assessment.

The effect of natural products used as pesticides on the soil microbiota: OECD 216 nitrogen transformation test fails to identify effects that were detected viaq‐PCR microbial abundance measurement

Published: Jan. 20, 2024

Abstract BACKGROUND Natural products present an environmentally attractive alternative to synthetic pesticides which have been implicated in the off‐target effect. Currently, assessment of pesticide toxicity on soil microorganisms relies OECD 216 N transformation assay (OECD stands for Organisation Economic Co‐operation and Development, is a key international standard‐setting organisation). We tested hypotheses that (i) fails identify unacceptable effects microbiota compared more advanced molecular standardized tests, (ii) natural (dihydrochalcone, isoflavone, aliphatic phenol, spinosad) are less toxic compound (3,5‐dichloraniline). determined following three different soils: ammonium (NH 4 + ) nitrate (NO 3 − concentrations, as dictated by test, abundance phylogenetically (bacteria fungi) functionally distinct microbial groups [ammonia‐oxidizing archaea (AOA) bacteria (AOB)] using quantitative polymerase chain reaction (q‐PCR). RESULTS All exhibited limited persistence, with spinosad demonstrating highest persistence. None showed clear dose‐dependent NH NO levels observed were <25% control, suggesting no impacts microorganisms. In contrast, q‐PCR measurements revealed negative total fungi, though one studied soils, significant reduction both AOA AOB across soils. This was attributed 3,5‐dichloraniline. CONCLUSION Our findings strongly advocate revision current regulatory framework regarding microbiota, should integrate well‐standardized tools. © 2024 The Authors.

Agroecological transition: towards a better understanding of the impact of ecology-based farming practices on soil microbial ecotoxicology

FEMS Microbiology Ecology, Journal Year: 2024, Volume and Issue: 100(4)

Published: March 12, 2024

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

Nanopesticide application should enable efficient pest management with smaller doses of an active ingredient. Nevertheless, the environmental risk assessment nanopesticides is currently in its initial stages due to limited access nanopesticides. Therefore, we synthesised nanofungicides captan as organic ingredient and ZnO35–45nm or SiO2 20–30nm nanocarriers ([email protected] [email 20–30nm) evaluated their by testing different microbial parameters potential biomarkers. First, physicochemical analysis (SEM-EDS, XPS, FTIR) confirmed presence nanofungicides, they maintained 43–61 % antifungal efficiency against pathogen fungi compared captan. Second, a laboratory toxicity assay (spot test) showed that generally revealed 10–100-fold lower growth inhibition non-target strains Next, effect on abundance, structure function soil microorganisms was during 100-day microcosm using orchard control, captan, nanocarriers.
