Q.White Beads on Sago
My sago palm has acquired white beads at its base and a cloudy film in the center. Has it got a disease? And if so, how do I get rid of it?

Sounds like your plant may be affected by scale or mealy bugs, which normally infest the lower portion of the plant before moving upward. Prune off all affected fronds and dispose of them. Treat with neem oil, making sure to get the undersides of the fronds. You may need to reapply weekly for up to five weeks.

If the white stuff is powdery in nature, then powdery mildew may be to blame. Since it is also an effective fungicide, neem oil will also help with this fungal issue. This articlehas more info:
