Young mango tree trunk drying

herman wang starts with ...
Hello,

I have a 1 1/2 year old mango tree grown from seed, and I see that the trunk, which used to be green, is starting to turn white/brown and it looks like it is drying up. Is this normal or is it a disease of some sort?

I have attached a pic.

BTW, the lower leaves looked burnt up because I sprayed too much chelated iron.

Thanks for your help!

Anthracnose because of excesive humidity, and probably lack of enough sunshine. Copper fungicide, and alternate with Daconil, or Dithane, or any other Mancozeb fungicide type. Put your seedling directly under the sun, or artificial light in case your clamate is too cold up there.
Feel free to write me if you have any question about mangos.
Best regards
Sev

Thanks for your answer. I don't think it is anthracnose because I do spray with copper-based fungicide - not because it shows infection but as a prevention. Don't mind the leaves looking old because, like I said before, I sprayed too much chelated iron on the leaves which burnt it. I have the mango tree outside in a greenhouse so I think it does have plenty of sunshine.

The tree is pretty healthy and growing vigorously. I'm just wondering why the lower trunk is starting to turn brown and dry looking.

Thanks.

Herman - maybe it's the chelated iron that has burnt the trunk as well? Did u mix it too strong or do it on a hot sunny day? Maybe if the growing tip is ok it will survive.
