cottony cushion scale - help!
Comments (1)I'm not going to try to interpret "environmentally responsible" but just give you what I think will work. First, neem oil is supposed to be good on scale, but it can take a while to work initially. For a quick kill, I'd use a little malathion (it shouldn't take too much). For what it's worth, my experience has been that the quick kill it offers means using less insecticide in the long run (though I do use soap first on most insects, just not much success on scale)....See MoreHorticultural oil vs. neem oil
Comments (7)Thanks for the feedback, everyone! I'm sure the effects are also highly dependent on the strength of the emulsion. I will say this about horticultural oil, though... it doesn't cause post-spray stinkiness like neem does! I think I have a new go-to during the winter months when I have to co-exist with my trees indoors. I'll probably fall back to neem in the summer months. -Tom...See MoreCottony cushion scale?
Comments (5)So I wouldn't use system on this one either, for the bees. If it's bad, you could cut it way back and I think these regrow from the roots. one of my orchid groups swears by "Margot's Mix". I've never tried it, but it's supposed to kill almost anything. 1/3 409 cleaner, 1/3 rubbing alcohol, 1/3 water, with a couple of drops of dish soap. This will be a long fight. Some scale will even get underground and latch onto the roots....See Morecottony cushion scale
Comments (6)I suggest you feed the tree with a good, balanced fertilizer. Chick manure - only - would not be adequate in my yards. A well fed tree without ants will fend off pests far better. Oh and organics take months to work. Too late in the season if you are in the northern hemisphere. Next spray with a hort oil solution, and repeat in 5 and 10 days. I suggest an evening spray and not when temperatures would go higher than 85. [ I've been ok with 90 the following day, but I think got lucky]...See MoreKimmsr
