My Breadfruit turns 2 years old next month! For reference, the wall and fence around it are 6 feet tall.
So this white film seems to be spreading across the fronds of my coconut palm. It doesn't seem to have a direct affect on the palm but it is covering the green on the leaves preventing sunlight absorption thus inhibiting photosynthesis. It doesn't seem like powdery mildew, anyone seen anything like this and is it curable or a life long issue?

Recent reader, new time caller. I live in Tampa, FL and have a Canary Island Date Palm that was recently diagnosed with palmetto weevils. Our local arborist was not able to come out quickly, but successfully and accurately diagnosed it with images and a phone call. Despite everyone that I spoke with saying that the tree should be pulled, I read some guidance on this form as well as from a You Tube video suggesting a few courses of action, including:
Fertilome Tree & Shrub Drench Gallon and
7.9% Bifenthrin Concentrate for Insect Control, which as the gentleman in the video (who was dealing with severe issues in South America suggested), I applied by drilling into some of the lower fronds with a 1.5" auger bit in order to spray the Bifenthrin into the bud. I also dumped some fire ant powder into the top of the bud, again something else that I read on a forum. I was desperate and was trying whatever I could. I only removed fronds that were drooping and brown with weevil tunnels...trying to give the tree a chance by leaving the greener fronds (mainly on one side as you will see). And I have remained patient.
That was all back in March, it is now Mid May. I've done some repeat application between then and now of the Bifrenthrin. The fronds that were not infected have held up all this time (see pictures). And most recently, there are some frizzy new frond spikes that have started to emerge (again, see photos). My question to this illustrious group is, (a) is this actual new growth, (b) is there any chance this palm will survive and recover to some sort of decent life, and (c) at this point, what should I do to help the palm?
Thanks in advance for the replies. This is a whole new ordeal for me...not necessarily the greenest thumb, but I've put in a lot of effort. If this guy survives, I'm popping some serious champagne. Be well!
This topic is started to document the cold damage, or hopefully lack thereof, due to the cold spell.
Initially, it looks like most of the damage done locally was due to frost. As you get outside of town, the damage can get pretty severe on the "high-9b/low-10a" palms that have become more common due to the advent of Lethal Bronzing. I'll begin with this photo I captured west of the airport on Medulla Rd. The damage didn't even wait for the warmup to manifest. For my own garden, I'm going to wait until it warms up to do my report. There may be palms that look undamaged now that will show damage after the next three days go over 80F. There may also be palms that appear to have light damage that have more extensive damage than shows at first.
@GoatLockerGuns was kind enough to compile his results from the Texas 2021 freeze in a spreadsheet that was easy to import into the Cold Hardiness Master Data. If you'd like to do this as well, I can assist if necessary.
