    What you are seeing is an infestation of mealybugs. It has likely populated the root zone, in addition to the leaves, so you should apply a good commercial insecticide, wetting 100% of the exposed vegetation and thoroughly soaking the potting medium. Repeat two additional times at one-week intervals, as insecticides, for the most part, do not affect eggs and immature insects, so the subsequent treatments ought to kill them as they mature and hopefully, before they can reproduce.
