Jeoff. and Martin,

Thanks a lot for that.

The weedkiller to which I refer is known as Spasor Biactive Herbicide.
A solubable concentrate containing 480 g\l (41%) isopropylamine salt of
glyphosate, equivalent to 360 g\l glyphosate.

Would your comments i.e. that it is safe to plant in land to which
Glyphosate has been applied, apply to Spasor Biactive Herbicide?

Just check the small print to make sure "biactive" doesn't mean it also
contains some other more persistant weedkiller as well. I knew someone
who used "Pathclear" on their lawn. It killed the weeds OK, but it was
the devils own job to get grass to regrow on the bare patches.

Glyphosate is astonishingly lethal to green plants considering how
relatively benign it is to mammals.

You have more to fear from the surfactant wetting agents than from the
active ingredient. By the time the weeds are dead the glyphosate will be
totally inert on the clay and partially decomposed to boot.
