Fluffy growth near stem

[DTB]

Can anyone help me.

I have no idea what orchid this is. It was given to me and they did not know.

I have had this plant for over a year moving it from area to area, pot to bark trying to get it to grow. It has not changed the whole time (at least it wasnt' going backwards and dying)

It has finally sent out some new growth so I seem to be on the right track but there is white accumulations on certain area. I am sure this is a pest but do not know what it is or how to treat it.

Any ideas? I would also prefer a more organic, natural pesticide if there is one that would work as affectively.
I wipe the plant down and remove as much as possible but it keeps returning.

Many thanks

Could the yellowing be related to the other problem?
