    I think you might be right on a Section 18, libhart. Why doesn't the company seek full registration?

    Wow, your post gives me a deja'vu feeling...this exchange parallels one held on the floor of the main lecture hall at the Auburn University Honey Bee Symposium a couple of weeks ago. Interesting.

    So we've got authorities(?) in two adjoining states saying (apparently emphatically) that hopguard doesn't work. Yet we have beekeepers reporting that it has worked well for them. At the risk of being redundant I'll say once again..."interesting".

    The company's literature may be at fault.

    Last time I looked (which was a while ago), it did not make clear repeated applications are needed if there is brood in the hive.

    So, if somebody took that at face value, and treated a varroa infested hive that had brood just once, they could come back later and test for mites and conclude it didn't work.

    During my own communications with the company on this issue I felt they were being deliberately evasive, there was just no way they would give me a yes or no answer as to wether repeat applications are needed in a hive with brood. Kinda felt they wanted me to "just buy it".

    If this has resulted in important decision makers now feeling the product doesn't work, then hopguards own obtusification has come back to bite them in the butt.
    44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).

    I believe that Randy Oliver states that if a lot of brood is present you need to do Hopguard applications for three consecutive weeks for it to be very effective. It does work when there is little brood. I plan to use it when there is little, to no, brood.

    Oldtimer, you're probably correct that hopguard's own communication may be causing them problems. I wonder if they are hesitant to talk about using hopguard in ways not included on the label due to legalities? Regardless, it appears that the treatment works with some tweaking and is relatively safe and non-toxic (to us and the bees). If this is the case then the bees and beekeepers in states where it's not allowed are losing out on a possible good thing.

    At this year's or last year's association meeting in Montgomery it was stated that we only have a couple of section 18 permits that the apiary division can use and that they want to use them wisely. I was looking at the EPA website and it looks like the two section 18 permits are for coumaphos for varroa and shb. Are the permits for a "type" of pesticide or for a "brand" of pesticide? If the permits are for "type" then it seems they could do away with one of the coumaphos permits and use the other one for something else. Looking at other section 18 permits for other crops I see duplicate chemicals for them, too. I'm just trying to understand this a bit...anybody want to explain how this works...in regards to type or brand?

    Someone posted earlier on this thread that they heard something about work being done on a Hopguard 2, has anyone else heard anything about that? John

    I suspect that it would work similar to the new Apivar, which also works via contact. Some sort of slow release strip that sits in the hives for 4-6 weeks.

    That may have been me that mentioned a possible Hopguard II earlier. It was mentioned by one of the authoritative figures in one of the main meetings at the Auburn symposium. Seemed there were "chuckles" or something between the speakers while talking about hopguard so it may or may not have been said in seriousness. It seemed to be somewhat of a strange exchange...

    It is expected to be available by mid-summer. It's anyone's guess in what states that might be. It's hoped to be a long lasting enough strip that would work as a "one and done" treatment even with brood in the hives. We'll see.

    Are they going to pursue full registration on this one, do you know, Jim? Seems odd to me to be building a business and developing a line of products like this that rely on emergency exemptions. I guess if it works, keep doing it, but it suggests to me that the product is only intended to be on the market for a few years.

    For someone who has never treated their hives, that being me, I am looking forward to using something that is not a chemical treatment and evidently does not hurt the bees. Although it is expensive I could justify using it on my hives as I'm not in the hundreds of hives yet. From the majority of reports it does seem effective if used when there isn't much brood, now if it could only be effective against mites in the unsealed brood that would be even better, although that may be stretching it.

    I have been waiting and hoping for something like this to come along because I am so dead set against treating, but I have begun to realize I need to do something soon because I am beginning to see hive collapse with high mite loads this year after many years of just getting by. John

    I don't know but I would assume so. My information comes from a presentation given at the most recent AHPA convention. The impression I was left with is that they are currently in the registration phase as they indicated all their testing results have been very encouraging and they mentioned availability perhaps by mid summer 2013.

    If it did not work, my girls weren't told....they are doing great! i gave three consecutive weekly treatments last fall ending by mid October - temps in the mid 60's to mid 70 degrees. On the last application I just left the strips in. I am in the Appalachian Mountains and we have a bit more of cold weather to go I am pretty sure. Though today is in in the mid forties and they are pretty active. I will use the treatment again in the spring per directions and see how it goes....so far, very pleased.

    Does anyone have experience with hopguard on first year hives that started as packages?

    Not packages, but I started two first year nucs that I purchased. They were treated in the spring with Hopguard and by myself in the fall. Both overwintering well.

    I cannot purchase in CT but I had a friend from MA give me some last fall and I used the strips in three of my production hives. All three are still alive and it's been a long cold winter! I just checked the Mann Lake site and Hopguard is still not available in MA again this year or CT. New York is though! Its getting closer. :-)

    I've been following this thread and it looks to me like the vast majority of people who have used Hopguard have positive things to say about it. I hope the good results with the product indicate that we may finally have a non-chemical treatment that will keep the mites under control and is fairly easy to apply. John

    a post on bee-l from canada's Medhat Nasr, I'm not sure what the second 40% kill means for the method most people are using here ie 3 times at one week interval.

    http://community.lsoft.com/scripts/w...F=&S=&P=188880

    Peter and others: I have a student just defended her M. Sc. last week. One experiment testing HopGuard showed that the efficacy is about 40% mite kill in the fall with a single application. Repeated experiment with 3 applications in the spring once every week yielded same efficacy (40%). Bees clean up and chew the strips within 4-5 days. Kill was high within 1-3 days max. HopGuard has potential if the application method modified.
