I've found that once certain tillys are crook, there aint no saving them. A healthy tilly will fight of diseases to a certain extent. They should be fine. They are like ferns and cycads and find insecticides quite toxic. Avoid using if u can but if not, go half strength and see how it goes.

Thanks, Tim. I'll just keep an eye on them. Because I let them dry off completely after their soaks, I don't reckon they'll be very susceptible to fungi but then again I do not know a lot about plants. It is amazing to me how plants fend off diseases, plant immune system etc.

I was wondering if you had a brand of fungicide you recommend?

Physan 20 for a fungicide
I use diluted soil surfactant (wetting agent) as a spray to combat pests. No worries about toxicity harming your plants.

Thanks a lot, Gonzer! Wow, I have been lurking on these boards for some time now and feel like I am interacting with a celebrity! :) I will get physan 20 for my tillys.
Diluted surfactant---I sprayed my tomato plants with dilute dishwashing liquid ( to combat what I thought was a hornworm attack). Would that work? Or would soap suffocate airplants? Thanks again!

Thanks for the compliment but rest assurred...I'm no celebrity! You're correct in that the dishwashing soap may clog the stomata of the tillandsias. Simple de-natured rubbing alcohol works well too. Many times clumps can fall apart due to a fungal infection or rot. Salvaging the healthier plants it's not a bad idea to dip the base of the plant in a powdered rooting hormone. These usually contain a fungicide to ward of nasties. You're not actually treating the plants to get root growth but rather to fight the infection.

Thanks for the recommendations, Gonzer! I would definitely like to try the powdered rooting hormone with fungicide. However, rootone is unavailable online at least. I was unable to track down any other rooting hormone with added fungicide...:(
Merry Christmas!
