Mango problem

can someone tell me what is wrong my mangos and what I can do about it! The mangos seem to be rotting at the stem and some have what looks like pine holes, some fall off the tree prematurely.

I have more pictures but the system will not let post more than one at a time

They look like pictures of anthracnose. Do you treat for fungus during flowering? Any issues of leaves or stems?

thanks for your reply!
I have not treated for fungus (Am I too late to treat for this season) and as for the leaves they have had some spotting but nothing major and no issues with the stems as far as I can tell.

What do you recommend that I treat the fungus with?

I’m definitely not a mango expert but this picture looked like yours:

And this site had good treatment recommendations:

I’ve used liquicop for fungal diseases for several other types of fruit trees. Make sure you pick up and dispose of any affected fruit and leaves
Good luck!

If ur on Facebook, there is a whole group on Mangoes. There are a lot of experts on there that will give you good advises.

do you know the name of the group?

Thanks
