Terrestrial ecotoxicity of glyphosate, its formulations, and co-formulants: evidence from 2010–2023

Abstract Glyphosate (GLY), the most widely used herbicide in world, is frequently detected various environmental matrices, including soil, foundation of agriculture. In practice, more than 2000 GLY-based (GBH) products are used, consisting one or active ingredients (AIs) and so-called “inert” co-formulants that increase efficacy AIs. However, focus ecotoxicological assessments mainly on AIs, while organisms exposed to complex pesticide formulations under real-world conditions. Overall, effects non-target indicate a broad range biochemical physiological modes action, which contrasts with general assumption herbicides specific act only target plants. Both GLY alone GBHs have unintended side-effects many terrestrial organisms, plants, microorganisms, insects, spiders, earthworms, as well vertebrates such amphibians, reptiles, mammals.

Most studies examined short-term single application GLY/GBH species. agricultural practice applying two three times during cultivation season over an extended period time, interactions other pesticides agrochemicals applied same field, within field landscape rarely considered. vast majority cases, toxicity exceeds GLY, demonstrating supposedly inert either toxic their own right interact add The chemical diversity different non-disclosure make it difficult attribute substances GBH. Moreover, impurities (e.g., heavy metals arsenic, chromium, cobalt) pose additional environment food safety risks. These impacts even critical because so distributed worldwide pollutants stressors. Based available literature ecotoxicity, given drastic decline biodiversity, we conclude continued high use GBHs, resulting increased exposure risk, cannot be considered ecologically sustainable.

Nature-Based Herbicides and Micro-/Nanotechnology Fostering Sustainable Agriculture

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(27), P. 9900 - 9917

Published: June 26, 2023

Bioherbicides, also known as nature-based herbicides, play a crucial role in sustainable agriculture by effectively inhibiting weed growth and development. They help increase crop productivity reducing competition between plants for nutrients, water, light. Their eco-friendly nature sets bioherbicides apart, promoting environmentally conscious farming practices. Despite their numerous benefits, many bioherbicide compounds are inherently unstable susceptible to environmental degradation temperature, light, humidity, microbial activity, thus posing challenges effective management. To address this issue, growing emphasis has been placed on encapsulation strategies recent years. Encapsulation techniques offer several advantages bioherbicides, including enhanced efficacy, biological compound release, factor protection, shelf life improvement. Polymers, particularly biopolymers, promising materials micro-/nanoparticles. These particles specifically designed the targeted delivery of ensuring protection Micro-/nanotechnology incorporation encapsulated formulation development revealed notable potential. This study focuses latest developments into micro-/nanoparticles practical application By leveraging micro-/nanotechnology, researchers aim maximize bioherbicidal paving way agricultural management The findings may serve reference expanding use micro-/nanotechnology-associated providing potential control solutions.

Glyphosate and a glyphosate-based herbicide affect bumblebee gut microbiota

FEMS Microbiology Ecology, Journal Year: 2023, Volume and Issue: 99(7)

Published: June 14, 2023

Pollinator decline is one of the gravest challenges facing world today, and overuse pesticides may be among its causes. Here, we studied whether glyphosate, world's most widely used pesticide, affects bumblebee gut microbiota. We exposed diet to glyphosate a glyphosate-based herbicide quantified microbiota community shifts using 16S rRNA gene sequencing. Furthermore, estimated potential sensitivity bee microbes based on previously reported presence target enzyme. Glyphosate increased, whereas decreased diversity, indicating that negative effects are attributable co-formulants. Both treatments significantly relative abundance potentially glyphosate-sensitive bacterial species Snodgrasella alvi. However, Candidatus Schmidhempelia genera increased in bumblebees treated with glyphosate. Overall, 50% detected were classified as resistant while 36% sensitive. Healthy core have been shown protect bees from parasite infections, change metabolism, decrease mortality. Thus, heavy use herbicides implications ecosystems.

Exposure to a fungicide for a field-realistic duration does not alter bumble bee fecal microbiota structure

Applied and Environmental Microbiology, Journal Year: 2024, Volume and Issue: 90(2)

Published: Jan. 19, 2024

Social bees are frequently exposed to pesticides when foraging on nectar and pollen. Recent research has shown that pesticide exposure not only impacts social bee host health but can also alter the community structure of gut microbiotas. However, most pesticide-bee microbiota interactions been conducted in honey bees; bumble bees, native North American pollinators, have received less attention and, due differences their ecology, may be certain for shorter durations than bees. Here, we examine how fungicide chlorothalonil a short, field-realistic duration alters fecal microbiotas (used as proxy microbiotas) performance. We expose small groups

Bumble bee gut microbial community structure differs between species and commercial suppliers, but metabolic potential remains largely consistent

Applied and Environmental Microbiology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

ABSTRACT Bumble bees are key pollinators for natural and agricultural plant communities. Their health performance supported by a core gut microbiota composed of few bacterial taxa. However, the taxonomic composition community structure bumble bee microbiotas can vary with species, environment, origin (i.e., whether colonies come from wild or commercial rearing facility), it is unclear metabolic capabilities therefore as well. Here we used metagenomic sequencing to examine composition, structure, potential across two different Bombus impatiens suppliers, B. , three other species sampled sites within native range all four species. We found that varied between populations origins suppliers. Notably, Apibacter consistently present in some species—suggesting may be previously unrecognized phylotype bees—and lack phylotypes populations. despite variation high-level was largely consistent hosts, including related host performance, though activity remains investigated. IMPORTANCE Our study first compare genome-level whole suppliers In addition, profiled full time. Overall, our results provide new insight into function will help researchers evaluate how well studies conducted one population translate Research on increasing relevance continue discover ways social influence health, decline abundance.
