wisteria has some sort of disease

Question

My wisteria has struggled to flower this year and on looking closer, it has some sort of disease. The branches have like clusters stuck to them similar looking to like a tiny beetle or like barnacles. Not sure if I can get rid of it and what to use.

Answer 1

It sounds like your wisteria might have a scale infestation. Scale would look like "barnacles". For more information on scale and a course of treatment, please visit the following link:
