It has been an excellent year for insects with the heat and rain we have received. Most plants have had their share of insects including Sego Palms. Owners of Sego Palms must take special notice and care to protect their palms from an infestation of Asian Cycad Scale. The scale appears as small white lines all over the base of the palm moving up to the fronds.

This particular type of scale is very aggressive and difficult to control. It spreads quickly, through the air and through the soil attacking the root system. Cycad Scale will kill your plant and at a fast pace. Catching it early is the first step. Second and third; you will need not only an on-contact control, but you will need a systemic control. Horticultural oil can be used to smother the visible insects. All Seasons Spray Oil or any other horticultural oil will work well. A product with Malathion as the active ingredient is another on-contact control. A systemic insecticide with an active ingredient of Acephate should also be used to control any scale in the soil on the root system.
If some of the fronds are completely infested don’t be afraid to cut them off and dispose of them in a sealed garbage bag. Additional treatments may be required. Please be kind and don’t spread the bugs.
