Fungal infection of butia capitata?

Well I lost a CIDP to a presumed fusarium infection a couple of years ago and now the pindo adjacent to the old CIDP site has lost the bottom half or more of its fronds over the past 2 months and is exhibiting some pretty similar symptoms.  I know that a butia capitata is not supposed to get fusarium wilt like a CIDP.  

I am in San Diego.  Last year the pindo was growing well with 6-7 spathes of fruit last summer.  This year nothing but dead fronds. 

Watering has not changed, except the winter rain.  Spinklers are still working.  No overhead irrigation. Never trim the fronds until they are completely brown..

Anyone know what it can be?  Recommendations for treatment appreciated as well :) (Clearys, Aliette, etc).  Thx!  Jeff

Actually Butia's can and will get Fusarium Wilt, and sorry to say it sure looks like it.

Lived in Cape Coral, Miami, Orlando and St. Petersburg Florida.

Thanks!

Fusarium sp. canariensis or sp. palmarum?  I have not see any references indicating that either infects butia capitata?

I was hoping this would be more of a rachis blight similar to what is described here

Anyone else?  Think it looks like fusarium as well?

Looking closer to the center, the earliest lesions on the fronds appear to be black ovoid patches that are expanding over time.
