How many of you also use Cygon in the fall? I have only ever done this in =

the Spring. Is there a significant improvement?

Jules -- No amount of alfalfa, rabbit chow or any other FOOD will help
control borers. Use the Cygon 2E in late fall and again in early
spring/late winter when you see the first evidence of iris growth, It's
a systemic pest killer and will do in the little microscopic devils as
they go about their evil deeds (eating your iris, fans first, rhizomes
eventually).
I'm sorry you composted your irises. Often, the damage a borer has done
can be countered by cutting away the damaged tissue of the rhizome and
fan, giving it a rinse of 25% bleach solution, washing that off, and
replanting it. (Of course, if you've got a LOT of the particular
variety, it's easier to throw the damaged stuff away.)
