Sticky Pest on Red Japanese Acer

Anonymous added on May 28, 2016 | Answered

I have quite a lot of brown/white sticky things on my red Japanese acer. They are on the trunk of the bush. My neighbor thought it was some kind of spore, but I am not sure and would like to find what to spray it with to get rid if it.

A photo would aid in my identification but I will give this my best shot. My best guess, given that you used the word 'sticky' is that your acer is afflicted with a honeydew secreting insect such as scale, aphids or mealy bugs. For more information on these insects and a course of treatment, please visit the following link:
