The Q&A Archives: Sago Palms

Question: Is any one more familiar than UF Agri Dept about the Asian Scale that is attacking the sago palm in southern states?

Answer: The University of Florida has several web pages about the pest and their research into control strategies, including introducing natural predators. Read them at:

Texas A&M has the following website:

And the Central Florida Palm & Cycad Society relays the following:

Reports of Asian Scale sightings are becoming common in almost central and south Florida towns. Areas just seeing the scale for the first time, just 6 months ago are now becoming so infested that its hard to find a Sago palm that is "not" covered with scale. Extremely persistent and difficult to get rid of. Many report that if you treat the sago with pesticides consistently enough, you can rid the plant of the scale, while others are insisting the bug has the ability to armor itself away from pesticides and keep coming back because you cant completely kill them off a plant once infested. Some will remain in armor or dormant like state and try again for life after treatment is relaxed.

With so many professionals working on the problem, I hope there will be a control in the near future!
