LD50 is less than common salt.
Ummm... I know what these terms all mean, but strung together this way they don't exactly form a complete sentence.

If you're saying that median lethal dose for a tree is less hazardous to humans than table salt...
Nope, they don't use humans in LD trials.
Then were you trying to say with that half a fucking sentence? Don't fuck with my head like that, man! It is TOO fucking early for that shit!!!

Go study MSDS and toxicity lab tests and tell me how frequently any chemical needs be tested to be sure it meets its spec, NDA requirement and user safety.
Here, very few years while it's still available for sale.
Now, no substance is safe if used outside it's label recommendations and that's what its guidance is for...to protect us from ourselves.
You might appear to have a different spin on toxicities and in many cases you'd be right as many chemicals that were once used freely and in some cases leglistrated to be used are now banned as science has proven them to be dangerous to human health. Those that have stood the test of time like Glyphosate since the '80's are a shit load less toxic than some would have us believe.
