Hi Milt: On another bee group a few weeks back a couple of people mentioned hearing at EAS that the folks at Cornell found it to be not all that effective. Now mind you what I just wrote is simply me repeating hearsay. I did try sucrocide this last spring/early summer on some hives that overwintered. There were drone cells on the frames that had numerous mites. I did three treatments about 10 days or so apart using the recommended mix from the bottle and applied it after calibrating my sprayer. I thought it seemed to work. Checking back later I only saw an occasional mite in the drone brood. Complacency set in I guess. I was planning on treating again this fall, but late this summer I started to see deformed wings, phoretic mites and parasitic mite syndrome. As with you, I’d sure like to hear from others on their experience with it. Regards, Dick Allen -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
