Re: iris disease or virus

Good morning! I am new to this list and hoping for a little help or 
direction.  I have been growing several different iris for a couple of 
years now and have had to deal with odds and ends of disease (crown 
rot and the like) without too much trouble.  I have 3 plants which 
have developed odd looking leaves, very clumpy and spiky, rather than 
the elegant fan that iris usually develop.  The leaves are so 
tightly packed together that they are litterally ripping as they 
attempt to seperate.  The blooms stalk fails to grow and the 
bloom is happening in the middle of the leaf mess. Ick!  Today I 
learned of a virus called pineapple virus which I am guessing is what 
these plants have since the leaves look like pineapple leaves.  Is 
there a treatment, or do I need to eradicate these iris and the ground 
they were in?  I have been unable to find a quick reference, and my 
local library Iris tombs have little if anything on the diseases of 
these lovely plants.  Help!  Please!!  The rest of my iris are happily 
getting ready to bloom if not already blooming.  Will this problem 
spread?  Is there a vector? Suggestions for a GOOD iris book with 
photos of the various diseases and descriptions of the appropriate 
treatments would be welcomed.  Any assistance will be greatly 
appreciated.
Thank you.
