it only acts as a deterent to the casting worm which is of no benefit to
your rootzone


Can you explain that a little further?

The species of worm that leave casts on the surface burrow vertically,
aerating the soil. Can you explain the mechanism by which you avoid the
casts without disrupting the vertical burrowing? Do you mean that it
deters the worm from casting? Or it deters the species of worm that does
the casts?

Are you saying that this substance acts as a deterrent to one species of
worm but not another?

Yes, I agree Kay, it would be worrying to find some chemicals can
inhibit/deter earthworms.

Considering the way soil died in the areas where NZ flatworms ate all the
earthworms, I would rather put up with wormcasts than kill of beneficial
action in the soil!

I suggest you read the thread before posting the chemical deters not kills
the casting worm and is used for sports turf.
