I might regret commenting, but honestly I think the biggest risk with glyphosate is in its effect on beneficial microorganisms (eg in the soil, our gut microbiome). I just want to add that a lot of this research is in the early days yet, and more studies are needed to prove causation. But at this time I'm erring on the side of caution when possible. "Overall, these findings suggest an intriguing correlation between glyphosate exposure, changes to the gut microbiome and abhorrent development of the GABAergic system, HPA-axis and the formation of microglial cells. Additionally, metabolism of glyphosate by the microbiome may alter NMDA receptor activation thereby promoting neuroinflammation in otherwise healthy individuals. Glyphosate-induced perturbations to the gastrointestinal microbiome may influence the synthesis of many neurotransmitters, necessary for mental health and wellbeing, encourage the formation of damaging ROS and reduce bacteria thought to be beneficial during times of stress. While the understanding of this correlation is still emerging, more research to prove or disprove this relationship is warranted given the food system is known to contain glyphosate residues." Barnett, Jacqueline A et al. “Is the Use of Glyphosate in Modern Agriculture Resulting in Increased Neuropsychiatric Conditions Through Modulation of the Gut-brain-microbiome Axis?.” Frontiers in nutrition vol. 9 827384. 8 Mar. 2022, doi:10.3389/fnut.2022.827384 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8959108/#abstract-a.e.b.ntitle The above article focuses on neuropsychiatic conditions, but the gut microbiome impacts other systems as well including the metabolic, immune, and obviously the digestive system. Here's another relevant study: "Glyphosate inhibits the shikimate pathway, a pathway exclusive to plants and bacteria. Glyphosate’s effect on dysbiosis was not considered when making safety recommendations. Here, we evaluate the literature surrounding glyphosate’s effects on the gut microbiome and conclude that glyphosate residues on food could cause dysbiosis, given that opportunistic pathogens are more resistant to glyphosate compared to commensal bacteria. However, research on glyphosate’s effects on the microbiome suffers from numerous methodological weaknesses, and these limitations make it impossible to draw any definitive conclusions regarding glyphosate’s influence on health through alterations in the gut microbiome" Barnett, Jacqueline A, and Deanna L Gibson. “Separating the Empirical Wheat From the Pseudoscientific Chaff: A Critical Review of the Literature Surrounding Glyphosate, Dysbiosis and Wheat-Sensitivity.” Frontiers in microbiology vol. 11 556729. 25 Sep. 2020, doi:10.3389/fmicb.2020.556729 (I realize both studies I mentioned have the same lead author. I think it's possible I just like her writing style, or that she's been the most prolific at writing reviews on this topic. I promise there are other people writing about this I'm just tired and undercaffeinated.) FWIW the proposed effects of glyphosate on bees is due to its effect on the bees' microbiome. Motta, E.V.S., Powell, J.E. & Moran, N.A. Glyphosate induces immune dysregulation in honey bees. anim microbiome 4, 16 (2022). https://doi.org/10.1186/s42523-022-00165-0 https://animalmicrobiome.biomedcentral.com/articles/10.1186/s42523-022-00165-0 (There we go, a different lead author!)

r/gardening on Reddit: How dangerous is glyphosate really ?

Glyphosate is the most studied herbicide in history. For 50 years it has treated American produce. So it's pretty well known what the risks are. Basically, just read the directions on the bottle. If it gets on a plant, the plant will stop being able to feed, and die. In the soil it breaks down in a few days, and is rain safe within hours. Wear personal protection if you are nearby while it's being sprayed. Don't spray near pets or bodies of water. There is no risk from eating plants treated with Roundup (if they survive lol) as it is broken down naturally. If there was we would know by now from 50 years of people eating them.

I have a huge problem with the marketing. 'Joe' down the street will likely have no idea that the formulation has been changed. He's going to walk in that box store, pick up that jug, get home, and apply that chemical just how he always has - in his flip flops and shorts. This new formula hangs around. It's not safe to apply with the same approach as the glyphosate formula. Triclopyr hangs out in the soil for a substantial amount of time - even several weeks. Glyphosate is rapidly broken down by UV often in less than an hour. More on reddit.com

I worked in ecological restoration for 10 years. Herbicides were a crucial tool, and among them was glyphosate. Without it, invasive species control is virtually impossible, and not even a fraction of the habitat restoration we did would have ever been possible. People are right to have a problem with planting resistant crops and broadcasting glyphosate over everything. Stump applications, wicking, and other targeted applications using only as much product as necessary is what we did, and people need to understand the difference. Like most things, glyphosate is not inherently evil, but the way we choose to use it matters. More on reddit.com
