Red Date Scale insects are the reason for many shade grown Pygmy Date Palms (Phoenix roebelinii) Dying.
We have had some serious flare-ups of a scale insect on one of our relatively pest-free Phoenix species, the pygmy date palm (Phoenix roebelenii) This Phoenix is originally from the river banks in Vietnam and southern China and thrives in our environment, unlike some of the other Phoenix species, which are more adapted to desert environments.
The scale causing death of the pygmy date palms is the red date scale (Phoenicococcus marlatti) and has been reported in Florida for about 15 years. We probably got it from California, where it was introduced in the late 1800s or early 1900s on date palm offshoots from the Middle East. We then got it from California palms
shipped here. It seems that palms in shady areas or in lanai plantings are suffering the most. Those in full sun don’t seem to be bothered as much by this little scale. The mature scale is about 1.5 mm long, spherical, red or reddish brown. An infestation
appears embedded or nested in white wax with occasional gaps that reveal the red coloration of the body, like an exposed raisen. It tends to congregate on the white tissues at base of newly emerging fronds and is on exposed roots and the trunk.

Texas Phoenix Palm Decline (TPPD) has been confirmed at the UF-IFAS Ft. Lauderdale Research and Education Center in Davie in a cluster of sabal palms. We want to alert all green industry professionals regarding this very important development. Sabal palm are our state tree and need to be monitored for signs of infection and disease development. The first clue is the appearance of more dead lower leaves in the canopy than would be normal due solely to natural senescence or nutrient deficiencies. The second clue is death of the spear leaf, prior to death of all other leaves in the canopy. Eventually,
the palm canopy will collapse around the trunk as the bud decays. As cabbage palms die (for various reasons), the leaves will typically appear to have a bronze or reddish-brown appearance. Later, these discolored leaves become more gray-brown in color. See photos below courtesy of Dr. Monica Elliot.
