  Re: [Aroid-l] Scale Insects

Dear Sherry,

Aloha.

I use all natural or organic controls for pests. It is possible to control your scales using Orange Guard or if you are energetic...you can distill your own citrus peels. I have been using distilled citrus peels for all sorts of insects and it kills all on contact. You have only a few plants involved so control of your scales should be a piece of cake.

Read about the Cycas scale, Aulacaspis yasumatsui. That is the worst scale I have ever encountered. It kills the formerly iron-clad, Cycas revoluta and other types of cycads. That is the only pest I prefer not to deal with as I will not spray or treat my plants with more toxic chemicals. Orange Guard will work to kill this scale, but the infestations are so large and the scale so prolific, it would require constant applications. I had many dozens of Cycas revoluta on the border of my lot...now I have none. There is a biocontrol in Hawaii...a predator insect, but the numbers are too low at the moment for effective control.

Well, I would recommend the most benign solution to your problem before you resort to the "big guns".

Aloha,

Leland
