Issue with Canary/Robellini hybrid

[Stylo328]

A few weeks ago my canary hybrid, which had been doing fine in its current location for the past three years, started to droop. Within days all of the fronds had fallen. I fertilized, put down granular antifungal, treated with Bayer pesticide and also treated with ferti-lome. 
 

it sent up new shoots and in the week sense, those have also fallen. There is a new clump of spikes at the top but I am not optimistic.

 

This is the state of the palm today. I have all but given up hope. I would like your thoughts before resorting to cutting the palm down. 
 

thank you in advance.

Holy crap. I have never seen anything like that before. Whatever it is, that could well be terminal. Are you sure it definitely isn't pure CIDP? If so, they will not tolerate hot, wet, humid summer conditions in southern Florida. I think they handle cool, wet winter conditions better than they handle hot and wet summer conditions, which promotes fungal issues in the species. If it is a CIDP dominant hybrid, that may be why it is suffering. The hot, wet, humid summer conditions causing it problems maybe? 

Give it a bit more time and patience to see if it recovers, although it doesn't look good. If you are going to replace it, I would maybe go with a Phoenix Sylvestris, or Reclinata. Fingers crossed that one pulls through for you though. Do not water it at all from here on. Your water table looks pretty high there and the roots are probably saturated. Combined with high rainfall and high humidity above ground too, that may be the cause for the frond damage. Hopefully it isn't the dreaded Fusarium wilt. I have a feeling that palm is on borrowed time though.

Thanks UK.

 

My neighborhood is filled with CIDP. They are everywhere. One a few blocks away had the same issue as mine at around the same time. It was a pure CIDP and was about 12 feet tall. It is gone now. My neighbor’s CIDP, across the street, is just fine. I have three sylvestris and they are all doing great. This almost looks like it was struck by lightning but I know that not to be the case. 

 

I have a decent sized white triangle coming next week that I am considering putting in that spot. I’d like to try to figure out what is happening to this highbred in the event that it’s a soil borne issue. 
 

This photo should give you an idea of how it’s faring compared to its neighboring palms.

And my neighbor’s CIDP directly across the street.

Hmmm, having seen the other CIDP's on the street doing okay, I fear that the palm in question may have Fusarium Wilt now. You also mentioned that another nearby CIDP had the same issue a few years back and was removed. Do you know whether Fusarium Wilt is a problem in your area? Could contaminated pruning tools have been used on your palm over the past 6 months?

Definitely get some more opinions on it besides my own, but I don't think this is going to end well. If it is Fusarium Wilt, the palm will continue to decline, sadly. Your garden looks amazing there however. The Triangle palm would make a great addition, even if it is to replace the sick CIDP/Robellini hybrid. You will know in the next few weeks whether it is terminal.

My first impression is fusarium wilt and yes it is in SWFL. Too bad you didn't take photos of the palm before it lost all its leaves. Wilt killed all my queens, mules and Washy in 2014/15. They went from healthy to "what's going on?" to dead within 3 weeks. The disease is invariably fatal. If it is in your yard I would avoid planting any more Phoenix, mules, Syagrus or Washingtonia. Wilt is easily identifiable because leaves die 1/2 on one side of the rachis, followed by the second 1/2 shortly after. The dead fronds have a peculiar grayish-brown color. When you cut the palm down you can see reddish-brown discoloration within the dying trunk. My condolences

I guess it’s some form of bud rot as the spike is wobbling. This palm is set to come out this week and be replaced by a white triangle.
