Recently I have heard from a lot of people about their cycads having Asian scale infestations. Here is a quick procedure I use any time I get cycads from an area that is know to have a scale problem.
1. Remove all infected leaves (I remove all leaves)
2. 1/2 bottle of Hartz flea & tick shampoo for cats mixed with a large bucket of warn water.
3. Submerge the entire plant, root and all in the mixture for an hour.
4. Remove the plant and let dry for a few hours.
5. Inspect for any visible scale.
6. Plant in a container & water in with a mixture of Bayer tree & shrub insect control.
7. Spray with Ultrafine oil once a week until you get you first flush & it hardens off.
8. Continue with the oil treatment for two months.
Asian scale will get down into the roots of the plant as well. This is the reason I submerge the entire plant. I use the Bayer tree & shrub treatment every 2 months throughout the year. Systemics are the best at controlling scale. There are many brands available but Bayer is one that an be found at any box store as well as your local walmart.
Just what works for me & may be a help to other here.

Laaz,
I've heard coffee grounds can be used with great effect. I can't recall if you use it to spray or drench the soil, but the scale dosen't like it.

Dean the best I have found to work are the systemics, they are taken up in the roots & are passed on to the rest of the plant material.

Todd, I'm printing out your Anti-Scale recipe in case my coffee grounds don't work.
Old (cooled) coffee grounds are sprinkled around the plant on top of the soil right to the base ahead of a regular watering.
So far so good.
But my C.revoluta is pretty hyper now 😆

All, here is the link to the coffee article that I mentioned a few days ago:

Jody, You are also a mind reader I see. Just last night I was thinking I needed to look and see if their was an article on coffee grounds for scale anywhere.
Thanks a million.

I knew it could be used for scale. 8) Fortunetly, I don't have a problem with scale.

Wonderful news...wonderful! 😀
Coffee grounds will never again go into my compost pile.
BTW, I love how Tom Broome writes.
Easy to understand, not full of chemical formulas...just useful information.
I've never met him, but I get a picture of a man who is a natural scientist, and just plain curious.
Reminds me of a favourite uncle who made math simple by relating it to everyday occurrences.
I'm thrilled the solution isn't to buy more chemicals.
Tom Broome, our gratitude for saving our beloved Cycads!
Thank you for posting this, Mr. Haynes! 😀

I am personally prefer the chemicals over anything natural. Natural route takes to long to work in my opinion. Laaz I am with you If its small enough to dip I dip lol. If not I have a nice 2 1/2 gallon spray pump and I pump it with pressure and spray using a few applications. I tried natural ways to keep scale and mites off my over wintered palms. I had to apply the natural stuff over and over the whole winter until the mites and scale died. I use Chemicals once in the fall and it lasts me the entire winter. I know its your preference so dont hate me for being honest 😀 The bayer tree and shrub treatment is awsome!!

The alkaloids in coffee grounds seem to have some level of systemic properties in cycads. When applied as a top-dress mulch, the efficacy literally lasts for months -- and grounds are a WHOLE lot safer (for humans), environmentally preferable, and cheaper than even the less toxic nicotinoids like imidacloprid (the active ingredient in Bayer Tree & Shrub). After using coffee grounds on CAS here in Miami, I couldn't imagine using any kind of chemical again. Just my .02.

I'm with, Jody on this one. Not only can they have systemic properties they also act as a mild fertlizer.

Plus, didn't the grounds produce the desired effects after only 10 hours?
Fast enough for me.
I used coffee grounds on C.revoluta and my 6-foot hibiscus last year.
Hibiscus sulked for a month but Cycad is fine.
I was initially worried about acidification of soil; the article covers that concern.
Collecting grounds in a bucket for use this year.
But I do wonder what effect coffee grounds will have on soil-based organisms.
