[Growwine] worm damage

[Lon J. Rombough]

Might work better if you had your camera set for closeups.  All I get  
is a big soft blur.  The items in the background are the only clear  
parts.  Kind of a neat effect, though, with clear background plants  
framed by the holes in the leaves.

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.
