    Default What's going on with Hopguard?

    Can anyone tell me why Hopguard is being blocked by states? Actually as of last year some states that allowed it now have restricted it. Mass is an example. I have been watching the Mann Lake site and the # of states is dwindling. Very frustrating!

    Not sure but I know that many have been frustrated with the confusion of application. They did not make it clear that you need three successive applications. Maybe that has something to do with it. Not sure.

    I'm not sure, but Hopguard was given a Section 18 registration. Those emergency registrations must be renewed each year in each state. My guess is that the manufacturer simply isn't pursuing full registration, and might not be going through all the trouble and expense to get all the Section 18 registrations.

    Probably what Kieck says. Didn't make enough money in those states to renew possibly.

    Hopguard II is currently working its way through the registration process. It is supposed to last long enough to require only a single treatment. Early tests are quite encouraging. My guess is that is the reason the manufacturer didn't pursue getting full registration.

    I tried it and it was totally ineffective. Mite counts before and after were unchanged. Maybe I had a bad batch but I won't be purchasing it again.

    I'm not sure how effective it was for me either, hopefully what's left in the hive will survive though.

    Would you give us some more info on that Tim? Temps, populations, number of treatments etc.

    you have to realize this treatment has to be used with little to no brood present,

    A couple of comments at the Auburn Honey Bee Symposium last weekend were that it simply did not work, and thus...Hopguard II.

    It sure would be helpful when people report the results of using a treatment that they include the details of how they used it, temperature, length of application, number of applications, etc.

    Up till now, I've been reading mostly favorable reports on Hopguard.

    I don't think this is the case Ian though it is surely must be more effective with less brood present. The company suggests it is effective even in mid summer. The recommended dosage is two strips per 10 frame deep box meaning a double would need to be split and two more double strips placed down below. Also perhaps a follow up treatment or two at intervals follow up may be needed. I think that's the problem with mid summer treatment of large hives full of brood. It gets to be an expensive time consuming operation. However in my mind it would be ideal in an early spring application to safely knock back mite numbers particularly in smaller nucs and also as a fall treatment once cluster sizes have dropped below mid summer levels.

    3 hives that were crashing, 3 frames of bees with little or no brood and 30 count mite loads. After two treatments still 30 count mite loads. All three were ultimately robbed out and the mites were assuredly dispersed to other hives but was able to clean them up with oa dribble.

    I probably need to add that the count was "sugar shake" on 200 bees done before, during and at the end of two weeks. I just didn't see any evidence that mites were being killed. Maybe I had a bad batch. Maybe it is working for others but I'm past the days of putting something in and assuming it works if the bees live. The actual count is the measure of effectiveness.

    I don't know Tim. I am not a spokesman for the product, nor have I ever even used it but I have talked to some that have used it with good success. I look at it as just another tool that will no doubt work better in some scenarios than others, not a panacea. The real attractiveness to me is the apparent safety of the product with no real rigid treatment windows or temperature requirements though I would be a bit apprehensive about using it in real high temps.

    >>HopGuard® is most effective when used during the pre-pollination period (before sealed brood), mid-summer, and at the onset of winter brood development.<<
    >>HopGuard® may be applied up to 3 times per year, even during honey flow.<<

    Its like using an Oxalic treatment, or a flash formic, or sugar dusting,
    from the results I have seen, it is very effective, but has to be done when no brood is present

    I know beekeepers want to use it through out the summer, as they claim you can treat during a flow, but it doesnt mean it will be effective at that time

    You may well be right Ian, sounds like you speak from some experience. Perhaps the whole idea of summer usage relates to the fact that it is safe enough to be used during a flow. How effective that treatment is may well be another story.

    oh no Jim I have no experience,
    but ya, oxalic can be used during a flow too, but it doesnt work,
    neither does formic, or any of the other knock down control methods

    boy, if Hop Guard could produce a product that holds a longer treatment period, we would be in luck

    Im very excited about this HopGuard product. They just need a bit more time to develop it. Its not available up here yet, but i have already found a place in my operating system to include it as a nuc knock down treatment.

    The key is easy on the bees and queens, and quick to use, strips are the way to go because doses can be adjusted according the the hive size

    What is the mechanism of the effect? If it kills by volatile emissions in the hive atmosphere reaching a critical concentration, then it seems to me like factors such as hive volume, ventilation, and temperature - maybe even wind - during some period right after application would all come into play. If it works by direct contact and grooming then it seems like the current activity mode of the hive would be a factor.

    For example if the hive is busy trying to fight off robbing then they might not be doing a lot of grooming. I don't know.

    Almost everyone (including me) makes decisions by anecdotal evidence - I tried it, it didn't work, therefore it doesn't work. We often feel like that should be pretty conclusive, but it's not really a good method of making a decision.

    Hop guard isn't available in my state (at least I don't think it is) so I haven't tried it, but I sure do wish that it would fall out as another safe effective tool.
