I need a little help

Okay got the new plants, I think the new phals are gonna be okay, but one has something on the leaves that is perplexing me. It has four bumps on one leave, looks like and please I know this is gross but, the bumps look like hard white pimples, and about the same size as one. What is it? I have searched and searched the forum, and have not found anything that sounds quite like it. Maybe I was looking in the wrong place? Pleeeeeaaaaaaase advise, I am perplexed.

Okay, I know nothing about oncidium, I did go to AOS for culture sheet (see kevin I do listen). I was wondering if anyone knows anything about the specific one I have which is Onc. Gower Ramsey (Goldiana x Guinea Gold).

It is sickly, but I think I can handle it. I potted to sphag in a clear pot , I used Fred's technique of carefully wrapping sphag around the roots until it forms a little ball, and popped it into the pot on top of dry bark in the bottom.
It has one little bloom. I am considering cutting the spike to conserve the plants energy for healing, but do you cut the spike on these? It also had a couple spots of mushy rot on the outside of one pbulb which i treated with peroxide, and it is now just dry and brown. Does that sound about right? I want to get it right cause my son wanted it and he is 10. I knew I would do some of the initial work on it, and then figured he would take over.

Okay I think that is about it for the questions. any help is always gratefully appreciated.

I don't know about the bumps on your Phal leaves but we used to get bumps on some of our Apsen tree leaves that seem to fit the description. they were insect "galls". Some type of insect transforms from larva to adult in them. I'm not saying that is what you have just that is sounds similar.

Onc. Gower is a big, famous, war-horse of a cross that just about anyone who grows many Onc has. Whether they know it or not, it's usually what people imagine when they think "Oncidium". It's meant to give a big display of flowers. My first Onc. was a Gower Ramsey. The RHS database tells me it was first registered in 1977. I have seen it quite often at department and DIY stores which leads me to believe someone is mass producing them these days. Very famous and popular cross. TONS of brilliant yellow flowers.

Thanks, I was actually hoping it was a bug. I have also seen something similar on another plant long ago, just was not sure if it translated to orchids also, or it was some horrible killing plague lol. I doused it in neem, and then put neem directly onto the spots. I think I will try carefully scraping them off.

The info on the onc. is great. The boy will be so excited. He apparently has a good eye even when the plant is pathetic. The one bloom left is very pretty, and after I have worked on it the whole plant is looking much perkier even the bloom. pbulbs are firm even though they are wrinkled, so I will keep my fingers crossed and do my best impression of supermom in the meantime. Thanks again.

Brookn - I have never seen what you are describing on my phals, and I couldn't find it in a book. I know some of the pros won't cut off a leave for any reason, but if I absolutely don't know what something is I will chop it just to be on the safe side. I usually try a spray and systemic first, and if that doesn't work fairly quickly I won't hesitate. With that said, I have never once had more then a very minor infestation of anything go beyond a few days, and maybe this practice is why.
