Pink Rot - best solutions

[Peter G]

This Summer I halved my watering usage thinking that the Pink Rot may reduce, but it hasn't, it always occurs under the oldest leaf base. At this stage I normally wipe off the pink and spray the area with Banrot, this has been going on for years and I haven't lost any palms, yet.

I did however lose a Chambey and a Dypsis Pembana to bud rot during Spring, I'm not sure if this was due to Pink Rot.

Recently I have started spraying the bud area of all palms with Hydrogen Peroxide and next Summer and will reduce my watering again.

I'm living very close to the coast and from what I have read, I have the perfect growing conditions for Pink Rot.

Any suggestions would be appreciated!

Quarantine will be your only hope Peter. Don't recycle any of your dead palm fronds either. Burn the lot, or just dispose of them off site. Fungicides merely suppress fungus they don't outright kill them although peroxide would probably kill most things. The spores are your problem and to kill 100% of the spores would likely be impossible.

Just the morning dew and mild temps next to the coast would provide a good habitat for pink rot. If you've got a badly infected plant remove it and get rid of it.

That's my thoughts for what it's worth.

Thanks for the advice Ty.

The only palms I have seen it on are the Rhopalostylis and now one of the Baueri have began to flower it makes the situation much worse because of what is going on under the leaf base.

Although this has been present in my garden for years, most palms seem completely untouched by this.

I've had luck using a granular lawn fungicide w/ T-methyl as the active ingredient. I pile the grains where petiole meets the crownshaft and as water and dew drip down it filters through the granules and combats the pink rot.

Ever tried a root application of water mixed with aminoacids together with copper?

My neighbor did a systemic drench on a P. cocoides that had a nasty infection of pink rot. I gave it a near zero chance of success, but it pulled through. That was the first time I'd ever witnessed a "cure".

Keep up the fungicide applications then. Try rotating the ones you use too. Fungus can get used to whatever you use over time.
