Bonsai Fungus

[NOZZLE HEAD]

Thanks for this. I have used more systemic fungicides (Cleary’s 3336 and Daconil particularly) over the last few years, and am convinced they have had an impact on growth rates in my trees. I am not sure Mancozeb has as much of a stunting effect.

I expect all the stunting came from the 3336, not the chlorothalonil it is not systemic, just a really broad spectrum protectant type non systemic fungicide.

Phosphites which are the most systemic fungicide, quickly cause a root flush and that leads to more vigor, I use them to overcome transplant stress in newly planted orchards and see really good results.

I actually noticed it the first time with Daconil, and switched a year later to 3336 hoping it would not stunt growth.

Were you using “Daconil Action”?
It would have the same effect as the 3366.

Which disease were you targeting?

No, just this; treating Cedar-Apple rust on hawthorn, Chinese quince, and RMJ.

Thanks for this post. this answer my question regarding the black stuff on my maple.

@Brian Van Fleet May I ask you if you finally did the test to remove the fungicides to see if they were responsible for the lack of growth on your trees?



Thanks a lot

I no longer use Daconil on my trees, which I think was the one that slowed them down. This year I didn’t use anything on my hawthorn, and got good growth, but also quite a bit of fungal issues. Now that growth is slowing down, I’m using Mancozeb, which does a pretty good job.

Thiophan, carbendazim, or propiconazole... anyone have tree canker and/or growth suppression update?

How did you determine that it was anthracnose? Have you done the analysis in the laboratory?
