When in doubt peel open the back label and read it right there in the store.

I don't know the ways of Myclobutanil getting into the system. I do know there are things that go systemic and carry anything there along with them.
From what I've read on the forums Spectracide's official stance is not to mix Triazicide with Immunox. Since finding that out I no longer mix the two.

Just a thought, but wouldn't Bt work in your situation? I think its called Thurcide... I use it on my cabbages for cabbage loopers, other egg laying beasts.

Thanks guys. I think I'll return the Immunox Plus and just spray separately. Great point about the insecticide becoming systemic.

Frank, the extension recommends BT for when they are newly hatched, but is ineffective when they are foraging. The problem with winter moth is once they hatch, they float on silk from tree to tree, so either Permethrin or Spinosad is recommended at that point.

Application of myclobutanyl and permethrin will often overlap (almost always in my program here in southeastern inland NY). I'd run with the plus and I never use premixes but I put out at least 200 gallons of spray a day during spray time. For you I'd think this particular mix advantagious.

Finished with spray a month ago besides probably a single Indar ap. on stone fruit in a couple weeks.

Once trees are established I don't find winter moth much an issue with most varieties- you generally can spare a percentage of flower buds which is what they damage here.

Thanks harvestman. I guess I'll backtrack and hang on to the Plus until next season then.

It's interesting. The prevailing advice on this site has always been... "Read the label, read the label, read the label". I haven't seen any of the solid members recommend Immunox Plus before because the insecticide isn't rated for fruit. In to this, we mix the fact that permethrin isn't rated for apples after petal fall which is the time you'd most like to use it. That said, in the discussion I link to below, you can see where some very knowledgeable people have some very solid arguments about why you should be able to spray permethrin after petal fall. It's a slippery slope we're on, but I guess if you accept spraying permethrin after petal fall, then you might as well use the Immunox Plus.

Here is a link that might be useful: No Permethrin after petal fall.

Sorry, I assumed the label had been read. Of course if it isn't labled for apples it shouldn't be used for them. I'd never recommend going against a label.

yep, looks like there's a do not use plants for food or feed warning on the label that I missed the first time through. I think I'll hold onto it and just use it on the roses and azaleas then.

I would agree with the others about following the label.

However, the commercial label versions of Immunox and Permethrin have no prohibition for tank mixing the two chemicals with each other. I also don't recall university compatibility charts showing any incompatibility. Since both commercial products are labeled for stone fruits, I'm sure they are occasionally tank mixed in the field.

I remember someone mentioned they called Spectracide and the rep told them not to mix the two. I wonder if the rep really knew what he was talking about, or was just trying to give an extra safe answer. If he really knew what he was talking about, he should be able to explain why the two should not be mixed.

I got to thinking about that. If Immunox had the ability to bring other things systemic like DMSO does that would make it extremely dangerous and would probably exclude it from all food in any form. Anything could settle on a tree leaf and get taken systemic without your knowledge.

I'll be sure and let everyone know if I die from eating my cherries sprayed with an Immunox and Triazicide mix.
I'm flipping back on forth whether or not to mix them.

Olpea, I always love your thoughtful contributions. I still won't go on record as recommending anyone defy the label, but what goes on behind close gates...

It's always irritating when the same chemical has different labels and the law requires you to honor the one that happens to be on the package.
