Bill,
     I wonder if this type of mix would work on Iris Borers?  When I lived
in Kentucky, I tried Cygon once, with disastrous results, so I went back to
Lindane.  Of course, Lindane is bad stuff too.  
     Hopefully, some less toxic compound could be found to control the Iris
Borers other than the commonly used poisons.  
     I have not seen any borers here so far, and truthfully I am glad that
I have not had to use that stuff.
