Hi Glenn and all
On Glyphosate, my impression is the most important aspect of
toxicity is, in relation to frogs, the way it is bound to
detergents in many formulations. It is the latter, rather than
the glyphosate itself, which seems to be the major threat to
wildlife from this herbicide.
In consequence the National Registration Authority has
recommended that most formulations are not used near water
ways. But since frogs will breed opportunistically almost
anywhere care should be taken with many glyphosate formulations.
There are formulations which avoid this problem, one being
Roundup Biactive (sorry about the advertising).
I am not aware of any toxicity test on reptiles. They seem to
be ignored in most testing.
