I just recently learned about insect growth regulators while investigating potential solutions for my sod webworm problem. I saw that there were several mentions of IGR's in other posts, but I didn't find a thread dedicated to the subject. Please feel free to leave your comments/anecdotes/observations about IGR's here.

The first resource I found worth sharing is National Pesticide Information Center. On their page, they provide information about:
  • Pyriproxyfen (active ingredient in NyGuard, Archer, Pivot, Tekko)
  • Methoprene (a.i. in Precor, Meteor which is labeled for fleas)
  • Diflubenzuron (a.i. in Adept which is labeled to control Armyworms)
  • Neem Oil

I'm still relying on my pest control company for insecticides. I called both companies I use and neither seemed to be ready to use an IGR. Or maybe they were confused by my question. It's hard to know.

In any case, I wasn't able to find an insect growth regulator that was labeled for sod webworm, which is what I was coping with at the time of my research, so a pest control company and I are going to test out Acelepryn in combination with Bifenthrin to see how it goes for the remainder of this year and next year. They aren't promising anything, but I see Sygenta has a sod webworm assurance program based on Acelepryn in place for next year, so I'm optimistic. Sorry that I don't have more pertinent information to share at this time.
