It's trifluralin, a really nasty crap. We use it for tetraploid induction in the lab, and it has as a specific that a part evaporates as a gas, hence using that near cyps you would surely end up with mutation or very big problems.

It is very persistent in the soil, and its effects are on the mitosis, in fact it binds to microtubules, so even if you use very low rate, or you have very low rates residues, it will for sure make damages and mutations, no matter the concentration.

I like it when they call it 'natural'...
but the product MSDS is there:

One of the many papers mentioning gas transformation of trifluralin:
http://www.google.com/url?sa=t&rct=..._9DSBA&usg=AFQjCNEWZaXE9NFlWiWQ20nxizi7GP5CGA

type in google trifluralin phytotoxicity, or trifluralin persistance, or trifluralin cancer, you get a wide range of interesting ( US Governement for many) results...

Thanks!
Thats what I thought,but wanted a second opinion.

I dont buy into that ''Natural'' nonsense with anything.
