I feel like this happened to mine when it was over watered. That is just a guess though.

It's some sort of dieback, but I'm not sure what caused it. I've had this on my J-12.

One possibility is a nutrient deficiency which weakened the tree and allowed a bacterial infection. Have you been regularly fertilizing the tree with a complex mix containing minor elements?

It could be something new in our area. In addition to my J-12, I noted a neighbor's tree across the canal with dieback in the upper part of the canopy.

Do a google search on "mango dieback gummosis"

First of all, take off those dead leaves because they will be a source of infection. Second, Stop watering. Vermented may be right. Some useful things to know are how long it has been in the ground, what you are feeding it, and a picture of the whole tree may give more indication of what is wrong. Try not to overdo anything. Sometimes trees just need time to heal on their own. You can kill a tree with too much "Love". As to the leaking sap, it may be some bacterial infection. I have had a couple trees with small amounts of "gummosis" but they seem to be quite healthy. Just my 2 cents.

During the dry season, you should be watering your mango. Twice a week for 10 minutes seems to be a good pattern. Consistent watering prevents fruit splitting and helps with nutrient uptake. Since our soil tends to be shallow sand, it dries out very quickly.

Gummosis is often a symptom of copper deficiency, which can be an issue in our high pH soil.

While some mango trees can be "set it and forget it," you really want to establish a consistent fertilization regimen, especially if you have shallow Broward soil underlayed with builder's fill. My favorite mango combo right now is Har's slow release 0-3-16 with minors and sulfur to lower pH.

Lastly, a fungicide program is extremely beneficial. A good copper fungicide product once a month helps stave off anthracnose and provides copper, which is often lacking in our soil.

Jeff, it's watered 3 times a week for like 8 min at a time.... I spray cooler every month and it gets fed 4 times a year with citrus fert.. it's the only tree I have doing this! It's been in the ground for like 18 months and this seems like it happened over night

Yes.  Spray with Copper, several times.

Phosphite would probably be useful also.   There are many brands:  Foliar Phosphite, Agri-Phos, Organocide Plant Doctor, KPhite....

Optional--- good if only spraying with Copper--- but reduces absorption area to be sprayed with phosphite.

this happened to a couple of my mango trees last year. Oozing sap, slow die back and eventually killing the tree. Over watering and bacterial infection is the cause of it.

I think you guys are more prone to phomopsis out in the west. Here, our soil drains so fast that it's nearly impossible to overwater. During the rainy season, an inch of rain falls from the sky practically every day. There are a couple of isolated areas that have muck (which is similar to clay) and is prone to flooding. Miami-Dade also has a lot of marl which has the consistency of silty clay and retains water. But most of Broward and Palm Beach have fast draining sand which will be dry as a bone within 3 - 4 days of no rain.
