Glenn mango tree, not healthy need help south florida

[Bishop]

Have a several year old Glenn mango which doesn’t seem to be as healthy as I would like. Pretty sure I have scales and some amount of Anthracnose. Would like advice on addressing these issues, once fruit drops can take most steps. Also, what seems like a larger than normal number of underdeveloped fruits have fallen off the tree on their own, which has me concerned. I have done some reading but would appreciate if there is an service or person in the area who could do fertilizing, treatments and proper pruning at end of season to improve my chances of a much better year next go around.

Thank you

The two mango scales in the first picture have holes--- exit holes of the beneficial parasites that kill those scales.  If the majority of the scales have holes, no action by you is required.

Black sooty mold on leaves grew from honeydew produced by the mango scale before the beneficial parasites arrived.  It will take a while for the mold to starve and peel off.

PS:  I didn't notice this post before because I rarely go looking for new threads to respond to.  But I respond to the Mango Diseases, Pests, and Nutritional Problems thread almost every day that someone posts there.
