Up until now, I have been removing these fluffy, white things with a wet paint brush. Obviously removal hasn`t been complete, as they are now gathering in the joints on a flower stem. Can I use a paint brush dipped in, for example, isopropyl, to kill them, please, without damaging the plant?
Many thanks Kate
Yes.
Putting a spray head into a bottle of isopropyl alcohol really simplifies the process. Wet all surfaces of the plant thoroughly, allowing it to stand in the leaf axils. Repeat every 3 days for 3 or 4 applications.
One thing you may have to watch for is root mealie bugs. If they have colonized the medium and root structure, you're going to have to resort to "stronger medicine".
