We have a Sego Palm that has a white powdery substance on the fronds and seems to be killing them. What can I do about this.

You may have a scale problem.
See: rhapisgardens.com/sagos/

'bout halfway down under INSECTS

Edit found more information:

This is a particularly nasty scale bug, see:
http://www.issg.org/database/species...=814&fr=1&sts=

There is a link in the above link that will lead to:

A 5 page Word 97.doc that the issg reports has had good success with Organicide's the below link will give you the idea what to look for locally, you should be able to find it in smaller quantities.
/Insecticides-and-Oils/Organocide-Fungicide-and-Insecticide-2.5-Gallon
You do not want to mis-use this product, as it can be very harmful to you, and surrounding plants.

A less volatile product is Neem Oil.
You can make it yourself:
neem-oil-insecticide.html or buy it locally at an established nursery
