Phoenix Roebelenii Disease?

We were trimming our Phoenix Roebelenii and thecore, where all the new growth is coming out, is all caked white white stuff. Some small globs and it’s all over. Palms look great overall, just the heart area has this white stuff caked all over it. 
 

Does anyone have any insight to what this is? Is it useful? How to correct it?

Thank you!IMG_4873.thumb.jpeg.a2f5054ad4dcc6b03f5c895b0364dd7f.jpeg

Looks like a really severe infestation of mealybugs. I suggest first thing that you give it a thorough hosing off to dislodge as much of that crud as you can. Follow that up by spraying it or sponging it with insecticidal soap. Make your own by shaving bits off a bar of Ivory soap into a bucket of water. Finally,  drench the ground around the palm with a systemic insecticide containing imidacloprid.

Agreed on the mealy bug. Years ago, we had a very cold week of weather, well below freezing. Well, it did not kill the pygmy dates out right, they just never looked good for the remainder of the year. It wasn’t until the next spring, when I took a closer look, that I saw something exactly like you’re experiencing. Pretty easy to treat, although it may take a couple applications.
