New Apple tree with powdery rust

Hi all I’ve got a very young Apple tree and it appears to have bright orange dust stuff on it I looked it up and it says it’s rust but I’m not 100% what to use to get rid of it? Horticultural oil/fungicide?.. help would be much appreciated ☺️

    Could you perhaps put a close up photo of the leaves on here so that we can get an idea of the problem?

    I take it that the leaf is the same on the reverse? No little orange tufts?

    Is the tree in a pot by any chance?  If so, how big a pot, how big a tree, what sort of compost, how often do you water it?

    Take a look at this, especially photos 8,9,10 and 11.

  • Orange powdery  tufts both sides. In a pot but a decent size. Came from a cutting. It’s about 60cm tall in a 40cm round pot. Don’t know what type of compost it’s been potted in but has grown about 10cm in the last month but the orange powder seems to keep growing as I’m picking of infected leaves 
  • Thank you for thank you for your help

    Ah, by tufts, I meant tufts like these.

    No, I think that your cutting is fine. I wouldn’t worry too much about a few spots. It will grow out of it. 🙂
