Probably Mango Bacterial Black Spot

Spray with Copper and other anti-bacterials

Does copper help with bacterial spot?

Those products sound good.

These should reduce the spread of the infection, but aren't likely to kill what is already there.

If only a few leaves are affected, cut them off and put them in the city trash.

I will be getting deployed in the next few months for roughly 9 months including over the summer months(sadly I will miss any fruit next year). I have a neighbor who will be doing occasional walk throughs of the yard but no real work since he in his 70s. The very knowledgable guy I was going to have help just had another heart attack and his heart is only operating at 26% so he is out of the picture. The most I might be able to get out of him is some drenching and checking to see if whoever we get to mow didn't take out the sprinklers. The main trees I am concerned with are the mangos since they get most of the hate from pests out of all my trees followed by my citrus trees. My wife is useless in the yard and every biting insect out there makes a beeline for her and a mosquito bite on her last for a month so she isn't an option. So given that there will be minimum maintenance for my trees what can I do?

Any long term spinosad spray/drenching I can use? I only have 4 in ground mangos right now and 3 in large pots but they are in two different locations in the yard.

What suggestions? I figure anything good for mangos will probably apply to everything else.

Hoping to get a thick layer of pine bark nugget mulch around every tree in the yard before I leave to at least reduce weeds stress a bit.

Hmm, never seen those spots, I'm getting something similar on my starfruit growth.

I have a volunteer seedling tree that I have experimented on now and again.

It has looked terrible for a year or so, but my question is specifically about what appear to be scratch marks on the trunk, about 3 feet from the ground.
I would assume that it's some kind of physical damage, but don't know what would cause this.




The foliage looks bad in more ways than I can count.




Can insects or disease cause the scratch marks?  Or should I assume that the neighborhood cats have settled on this tree as their scratching post?

The trunk does look scratched by cats, etc.  If it seems to be on-going, applying stinky sprays to trunk and soil might stop it.  Spraying trunk with fungicides might give it a better chance to heal.

The leaves are deficient in pretty much everything, due to root starvation, from the downward movement of the sap through the phloem having been interrupted by the bark damage.

Thanks, Har. I see some fresh scratches on an otherwise healthy tree, so time to take action.

Also, I enjoy learning a bit of the science involved, even if it doesn't stick in my brain.  :o

Out of 50 mango trees this one has me puzzled. The tree is Juliette, and when I pruned it a few weeks ago it showed some signs of the same problem. I pruned off almost all leaves and it is recurring on the first flush. There are signs on the bottom of the leaves. Adjacent trees do not have any major problems, but i see a few instances of this happening on a few branches of one or two of them, but other leaves on them look normal. This Juliette tree, however is pretty much covered. I also noticed that the pruned branch tips of this tree are bleeding sap more than the others, enough that honeybees are collecting it for some use.

Lack of iron for new growth leaves?

The green spots on the new growth look like what often happens from nutritional sprays.

PineIslander, does that 'Juliette' tree have any trunk damage on that side of the tree, such as an imbedded strap?

These new leaves havent been sprayed.
I do wonder what this indicates.

Lemon zest


Maha Chanok









Pictured are 2 of my mangoes: Lemon zest in the ground and Maha in a 20g pot.
LZ didnít fruit this year and half of the new flushes donít look healthy. The MC fruited but looks like itís deficient on something. You guys have any ideas on whatís going on? Thanks.

When the soil gets too dry, even for just one day, the hair roots die--- so very little of any of the micro-nutrients get absorbed--- until new hair roots grow.

Avoid any fertilizers that just have NPK.

I see severe Iron deficiency, Manganese and Zinc deficiencies, and probably Copper and Boron deficiencies.

I currently use liquid copper fungicide ever month from the Home Depot, then from lowes i use Bayer advanced Fruit citrus & vegetable insect control every 6 months and Mango's haven't had a problem but that Citrus greening killed all citrus trees. To me it is easier to maintain Vs. fix the issue

Here I come with a strange (to me) case. Few months ago when I planted this Nam Doc Mai in soil, I discovered that ants and scale insects were coming into the very recent graft (a cleft graft). So I decided to cover the whole graft with this "healing paste" (I'm not sure how you calling it in English). Problem with insects ended there obviously, but this week I found that section swollen, so I took off the paste. This is what I found:







Any idea why this happened? Should I worry?

Thanks,


Jose

I'm noticing mango problems being posted in new threads everywhere, instead of in this dedicated thread.
