    Hello all;

    I have been seeing many recommendations for Bayer 3 in 1 for treating various pests. I struggle constantly with mealybug and some occasional scale. Not a big infestation, but just a constant presence.
    I am growing pleurothallis, restrepia, bulbphyllums and various miniature species.
    I currently use Azamax, which helps with spider mite, but it doesnt really seem to affect mealys. I do spot treat with alcohol, but that is time consuming and I miss some.

    Has anyone had any issues with Bayer in terms of leaf/root damage on more tender varieties? I only spray anything in the evenings as well to avoid possible burning. Most of my plants are on mounts so they would get a root drench when I spray. Or is there a better product than Bayer?
    Thanks.

    Safari works pretty well in knocking down populations.

    There’s a new product someone was telling me about. “Distance” is a growth regulator.

    Might be good to use in conjunction with your pesticide program.

    If a product isn't working, time to switch to something different. Bayer 3 in 1 has been in wide use and quite likely resistance is a problem. Safari worked well when I had resistant mealybug. If you have wooden frames for your hanging plants, mealybud can hang out there and re-invest.

    Good info everyone. Thanks. Marni, having not used Bayer before would resistance still be an issue? I assume the resistance would be built in to the mealybug population in general. I have read about Safari as well. My real concern is plant sensitivity with either product.
    And yes Marni I do have wood frames which are great hiding places for all sorts of critters.

    Sand, I have found Azamax to be quite good for mealy bugs. How are you applying the stuff?

    Three treatments (= wetting ALL plant surfaces and saturating the potting medium) at one-week intervals is my recommendation with ANY pesticide.

    Saturating the potting medium is a key part of that, as the critters can populate the root system, as well as the leaves and stems.

    A lot of orchid growers (including me) have used Bayer 3 in 1 or many, many years. I know that 10 years ago I encountered mealybug that were immune to imidacloprid so switched to Safari. My plants are so densely packed that hitting all surfaces is impossible so I go with systemics. Chances are if you have mealy bug they came from somewhere else and may have come with built in resistance. I have a varied collection with plenty of sensitive species/genera and have not noticed any problems with Safari. But eveyone's conditions are different.

    This is all very good info. Ray; yes I do soak everything with Azamax when I use it. I think I am a bit timid in that when I used to use Neem, some plants reacted badly. I have never had issues with Azamax but I still hold back to some degree in terms of really drenching plants.
    Marni; a few years ago I had a terrible infestation of a kind of mealybug I had never seen that made huge colonies in the wood framing I used. I had never seen anything like it. It was horrible. Next to my balcony there is a podocarpus that sadly suffers from a bad infestation of whitefly that I have spent years trying to control. I had thought that was what was living in my frames, but figured out it was mealybug. I have since rebuilt my whole system but I agree with you the mealys came from somewhere else.
    I may try Bayer first as Safari is very expensive and I havent been able to find small amounts and my space is so small I need very little.
    You all are so great with sharing info. Thanks. I appreciate it.

    I use Talstar P when plants are inside, which is a synthetic pyrethroid, and is effective on mealybugs, scale, mites, etc.

    It's not a systemic, and the active ingredient is a waxy, white substance, apparently dispersed in water to form a thick suspension. It has no odor. Available on Amazon.
