Well... I've got thrips.
I had read this thread or another similar one a few months back but when I read that you couldn't "see" a thrip and the bit about the rings didn't seem to look like anything going on with my Rhy.
Now I see the rings though... and they are now on all my vandas. I didn't do a Google Image Search back when I first read about the rings... if I had, I'd have seen photos of vanda roots that had "cracked" where the ring is... then I'd have known ... that my Rhy. has had thrips all along! It shipped to me like that a year ago & some of the same behavior out of the roots that I thought had been because they had gotten cold in shipment were likely because of the thrips... as several of my good-juicy roots have dried up & cracked where the "ring" was ... that stinks.
I know how it all got so much worse too... or I think I do. It was in the late summer when I moved some of my vandas around to catch some rain that we got off and on for about a week. Several of them were touching during their shower & this includes the Rhy.
I was noticing problems but just couldn't put my finger on them... now I see though and boy oh boy do I have problems now!
Do thrips like dends, catts, oncidiums & phals too?
Could this (thrips) be why my phals make bloom spikes but either stop spiking when the spike is about half grown... or grow quite long but don't produce buds... are thrips causing this behavior ??? I haven't had a phal bloom in nearly a year ... 3 of my phal type dends are blooming though, right now !!!
So I have some Bayer 3 in 1 under the sink. Should I spray or dip/soak or both?
