Answer
Hi Pejan,

If the "rust" doesn't brush off easily, then it is probably a scale insect infestation. Mix a solution of 5 parts water, 1 part isopropyl alcohol and a squirt of liquid dish soap. Then, spray all leaf and stem surfaces thoroughly until they are dripping wet. This spray will penetrate the hard shells of the scale insects and kill them.

If scale is not what you are seeing, then please provide a photo or a better description of just what are seeing.

I have written an article on treating plant pests that I will email for free to you (or anyone else) who sends a request to me at [email protected].

Please let me know if any of this is unclear or if you have any additional questions.
