From what I've read, glyphosate itself is pretty safe (how it works should only affect pathways that exist in plants).
The issue is more about the stuff it's dissolved in to be sprayed.
The issue is more about the stuff it's dissolved in to be sprayed.
The cocktail is designed to protect the solution in storage and transport, make it easy to mix into batches for spraying, atomise cleanly when sprayed, but then cling to whatever it is sprayed on, then get absorbed into the plant quickly.
It is those chemicals which cause wet membrane irritation, chemical burns, skin irritation and inflammation, etc.
The glyphosate itself is basically harmless to humans and any effect it might have on gut flora is overshadowed by the damage RoundUp will do to your throat and gut on the way through.
Basically remember to follow the directions including appropriate PPE: gloves, dust/mist breathing mask and eye protection.
It's also further proof that Monsanto is full of shit, always deceiving and lying as much as they can get away with. How much is it going to take before we make them stop?
Or, don't spray poison on food?
Enzymes and other parts of biological systems often share similar modalities, and if glyphosate targets a shared modality, it would affect any compound that uses said modality.
