RE: RE: Zone 6a and borer control

Hi,
I just use the bleach as a cleaner and perhaps a killer of eggs.  

I don't think any grower would ship borers knowingly and I do check every
rhizome I buy for problems.  Sometimes they are dirty and so the soak could
show a hole.  Also, they are still very small at my dig/plant time.
Thanks for the kind words, Mike I appreciate them.

 I am in prime borer land and have see hundreds of them. Not many if any 
commercial growers would ship a rhizome containing a borer or even a rhizome

that had damage. One way they get imported is by people trading and the 
e-bay sellers. Shipping bearded Iris in the spring when the borers are eggs 
or very small could spread them.

I don't believe an over night soak with a 1 to 10 bleach solution will 
safely kill borers. I have had borers crawl over 6 foot( through thick lawn)

from one bed in the summer to a bed of lined out seedlings. Those seedlings 
were lined out in early July and had to be moved in late August. I found 
several borers  and quite a few pupa in the bed.
