Thrips, mites and aphids; Oh my!

[Shrinkrap]

I did a quick search before posting. Hoping this is the right approach.

Over a period of just a few days, I noticed some discoloration on the lower leaves of my four week old tomato seedlings. They have been in Earhtboxes about two weeks, and the ones still in the seedling pots are unaffected.

Years ago I would have thought little of it, but last year a problem that started out fairly minor seemed to do some damage. (First two pictures)

Last year I recall blaming aphids (last picture), and 10 years ago I blamed (russet or spider) mites (second to last picture) , but THIS year, I'm thinking thrips. (picture three, four, five)

I've used spinosad for thrips on my nectarines, after years of scarring that I could not figure out. Much better now, although I understand spinosad is not harmless.

I've read Spinosid, and insecticidal soap works for thrips, but not as well, and that insecticidal thread works for mites and aphids.


Any opinions? Anyone know how long the soap lasts, premixed, and concentrate?
