not great pictures, look for the small black lines.  They are soft, squish
easily, all over the place.

 

Rain forecast for the next two days - would I be better to wait for better
weather?

Larry, 

 

Curiosity has got the best of me.  I'm stumped.  I can think a catapillar
that damages grape foliage in the pre-bloom to bloom stages that looks like
that.  My guess is it is a generalist pest, and not grape-specific.  Any
chance you could get a photograph before you do them in?

 

Another 'soft' (sensu OMRI) product you might consider is a neem-oil based
product.  I don't know about registration in Canada.  Last I knew that was
still in the pending stage for use on grapes.

We are having a problem with some small (about 1 cm long) black worms on the
leaves.  In some cases they have almost defoliated entire vines.

 

What is available to fight these (safely) without special access to
chemicals?
