Default Fluffy growth near stem

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?

Not sure but I would suspect a mealy bug infestation.
Apply something based on imidacloprid or thiacloprid.
I don't know hwat's available in New Zealand but Bayer has some good products for home usage (Bayer 3 in 1, I think, Calypso). Those are systemic which is the best option.
Isolate the plant to a place with lower humidity, remove the bugs you can see, repot with fresh medium, apply the product mentioned above once a week for 3~4 weeks.
Take a good look on the plants in the vicinity of this one (if any) because the probability of being also infested is really high.

I use a Q-tip dipped in alcohol to remove the pests after unpotting, then rinse. Helps get rid of the ones who may be lurking. Plus what rbarata says.

Looks like the juvenile form of scale on a Dendrobium with Den. kingianum ancestry. I would submerge the whole plant in a bucket of soapy water, 2-5ml of liquid dish soap per liter. Let it soak a few hours. Remove and scrub. For a heavy infestation like this you might need to repeat. Watch for scale on your other plants, too.

I think it would be hard to water a Den. kingianum enough on a mount. This is why it isn't growing. It needs daily watering during warm weather if mounted. I would put it into a pot.

I can't say what it is, but what it doesn't look like to me is mealy bugs. I actually have a bunch of this white yuck on my outdoor growing daisy plants and was just today trying to figure out if it was a fungus, or what.

Thanks for the advise. It has actually been mounted in a pot with daily watering for the past year, that is when it didnt grow, strangely, as soon as ive mounted it on the bark and put it in the bathroom, it has started to grow. (i do mist it every second day and it receives more humidity now so maybe that has helped) Even more interesting, it was planted with 2 other orchid for the whole time and neither has any sign of the same infestation but I will keep a close eye on them all.
Much appreciated

Your other photos show what looks like sun burn ( leaf w/ spot on it) and the green thing comeing up though the moss looks like a new root. The mealy bugs can be washed out with above advice. If one of your plants has mealy bugs then probably the other plants near by probably have then too. Keep a close eye on them too.

Hi Selmo,
Yes , the new root is super exciting, its the first sign of growth it has shown since I received it. Funnily, the 'sun burn' patch has developed while the plant was in a shaded area, that why I thought it may be part of the infection. There is new growth coming out from the top of one of the spikes now as well.
Rubbing the areas with alcohol and rinsing has really worked and there is no new sign of the infection. Fingers crossed!

King_of_orchid_growing,

The plant is now growing since I moved it to the Cork bark and placed it into my bathroom so you may be onto something with the Rock Lilly. It'll be interesting to see what this little survivor grows into.

Default Awesome development!!

So it seems that not only is the bug growth under control but it seems the plant is very happy with its treatment, new position and mounting cork!

This has been coming up the last week!

I am very excited because not only is it winter and very cold here in Australia at the moment but I have no idea what this orchid actually is!

i will post again once it has flowered and hopefully get you good people to identify it for me.

Hooray!!!
