It works for me. Goal was to get something vertebrate friendly, and all of those things are (in theory) quite safe. I sell a lot of plants to frog people, so can't use a lot of things.
Distance - an insect growth regulator, can't remember which class, but it has translaminar activity (it is a systemic, in other words). Enstar II would probably work, but I like systemics. It might only be available in large quantities, but you could come pick some up, Dot.
Azamax - active ingredient the same as in neem. I don't know if it is synthetic or purified. Neem oil has a long history of being less than consistently effective, so the standardized formula is more reliable. Azidarachtin is an anti-feedant and has a few other modes of action, I'm not sure anybody knows all of the things it does yet.
Spinosad is the active 'ingredient' in a beneficial bacterium - I buy it as 'Dr. Doom's Deadbug Brew', which is an evocative name. Worked well for me. I've heard it works on molluscs too, but I can't say that it ever has had that effect for me.
Anyway, if I did my research right, three different (maybe more) modes of action, so resistance should be minimal. Doesn't mean it can't happen... In my hands it did absolutely no damage to plants, I sprayed it on flowers and buds and everything in the barn, not a spot or blemish. The usual three times, a week apart.
Interesting Littlefrog. I did not know Spinosad. Maybe I shoud use it sometimes. Maybe I should aternate with Botanigard.
