Weed Killers: Lycoris and Lontrel

We spray with herbicides to help control weeds outdoors in the beds.  We 
usually start in the spring with a tank mix of Lontrel (R) and Fusilade II 
(R).  We can safely use this to overspray Hemerocallis (daylily) beds with 
no discernible damage to the daylilies.  The mixture suppresses grasses and 
broadleaf weeds like Canada Thistle and wild mustard.

We noted in the spring that Hosta are damaged by Lontrel, as people had 
warned us.  In the future we will try very hard to avoid getting this 
herbicide spray on the Hosta foliage.

Now I observe that some of the Lycoris are showing damage to the scapes 
which I suspect was caused by directly spraying the above mixture of 
herbicide onto the foliage of the Lycoris in spring.  The damage I'm seeing 
is twisted scapes and distorted flowers.  I will try to get some pictures 
of the damaged Lycoris and eventually post them in my blog.

Has anyone else seen problems with Lontrel on Lycoris?  Could something 
else be causing the damage to the Lycoris?  Only a few clumps of Lycoris 
are showing this damage.

Lontrel (R) is made by Dow AgroSciences; see:

good stuff!  (Always follow label directions.)
