The picture is just a little bit out of focus, so I can't it perfectly. It does look like yellow scale insects, though. Azadirachtin is the main chemical component of neem oil. This extract is best for scale. I wouldn't treat consistently. These are difficult to get rid of.
The scale pictured in the article is one of many different species, however it will still have the same treatment.
