Rust fungus or bug

[D. Morrowii]

A couple weeks ago I noticed some slightly sickly looking leaves on a couple of palms in the front yard. I tried spraying with a castille soap, alcohol and dawn mixture that I use for mealy bugs and scale but it didn't seem to have much of an effect. I bought some Daconil recently to treat some crown rot on a Veitchia and noticed it treats “rust funguses” The orange stuff seems to mostly be attracted to a couple coconuts and seems to be causing some premature leaf death.  I read a little on IFLAS website about it and it seems like it might be hard to knock down. Is this something serious or just treat with fungicide kind of thing? Thanks

It’s spider mites. They are a pain. Anytime we get a period of dry warm or hot weather they appear. They seem to like some palms more than others. You can buy a miticide. I usually spray the undersides of the leaves off with a powerful jet of water or on smaller palms, place one finger on the top of a leaf and the other on the bottom side and lightly squeeze it between my fingers starting at its base and working towards the tip. Btw, I think I remember you posting you have a neoveitchia, check the underside of its leaves, that is one they seem to like.

Thanks @Hurricanepalms I thought it was mites before due to the orange residue but the soap treatments weren’t working so I thought maybe it was something else. And yes you are correct the Neoveitchia is also affected as well as a Clinostigma savoryanum. I spent the last hour reading up on how to control them which doesn't sound like a lot of fun.

Mites love the dry conditions as hurricane palms he hoses them with a good blast of water increasing the humidity may help mites build up chemical resistance so a rotating spray program helps but the good old hose is a much more affective solution to chemicals the problem with chemicals is pretty obvious I never spray my garden it just creates a symbiotic nightmare putting the whole balance of Mother Nature out of whack not to mention health issues
