Imidacloprid is the active ingredient you will need to systemically control whitefly on your palms. Adonis would be the product of choice for soil drench applications for whitefly infestations. It can take a few weeks for the Adonis to translocate through tall trees and you will most likely continue to see whiteflies in that time period. While you are waiting on the imidacloprid to translocate you should treat the foliage with a product such as Talstar P or with insectidical soap or insecticidal oil.
