You never heard of it?  Probably with good reason.  I may have partially mis-spoke......or mis-stated what I was trying to communicate. 
Black sooty mold is, for sure,  a by product of pests.  In my yard it seems some trees have a perennial problem with it.  So is it that the pests like that tree more than others and so there is more sooty mold on the selected trees?  I imagine most of my trees have the same issues with pests due to their close proximity.  Yet, many do not seem to have an issue with black sooty mold.  So how would I better say what I have observed?  Lemon Zest seems highly susceptible to the insects that bring about black sooty mold?   Is that better? Bottom line, for newly planted trees, there is a wicked case of black sooty mold on both of my Lemon Zest trees, while there is none on many other trees contemporaneously planted.

Dan, how often are you spraying the Dot mango tree...I was reading the directions for mango trees on the Plant Doctor and it says:

"Spray tree every 14 days
during blossom period, then
monthly until harvest."

Wasn't sure...but, it sounds a little excessive and didn't want to apply it that often? Afraid of the long term affects. Any thoughts?

I have sprayed it on the Dot every two weeks, more or less.  I've been assuming that it's harmless, at least compared to some of the popular/effective fungicides from the olden days. The limited Googling I've done on Plant Doctor and another brand with the same stuff in it has not turned up any negative long-term effects.  (But then I thought copper was utterly benign until I read otherwise on the forum.)

 But the small fruit on Dot are quite speckled, so I started with copper recently on the whole tree, which has some new blossoms.  As I said, the weather has dampened my enthusiasm for non-systemic fungicides.

I only started with the Plant Doctor last year, so don't have an overall sense of how effective it is.  However, it does at least seem that the Plant Doctor got rid of powdery mildew on Rosigold both last year and this year.

Some trees do seem to be more highly favored by scale, lemon zest being one. I think it has to do with a couple of factors: 0) how 'sweet' the sap is and 1) how slowly the tree grows. I theorize that scale likes sweet sap and slow growing trees. Amount of sunlight also influences severity of scale problem (but the underlying cause could potentially be slow growth due to lack of sunlight). My glenn only gets sooty mold only on the north side every winter.

That said, I've seen lemon zest trees with and without sooty mold issues -- probably a factor of how established and therefore how fast it grows.

However, they seem to be fairly resistant to anthracnose. I'll see if I can take some snaps of my LZ flowers and fruit.

I have a cute little 1gallon LZ that's starting to flower at about 18 inches tall :-)

Tell me about it......

Maybe change it up and spray the copper after it rains  :)

Harry is right, as it does look like a multiple deficiency, presumably including of Iron and Potassium, and possibly Nitrogen, Sulfur, Magnesium, Zinc, Manganese....

Thanks Harry and Har!  Yeah, so I do foliar spray chelated iron, zinc, calcium, magnesium, as well as dynagro foliage pro once every week, alternating.  I also give it epsom salt when I water the roots along with dynamite all purpose fert.  The soil is just what came with it from the nursery.  I have not repotted it yet.  Now I did add some bonemeal last year, but I think I added too much of it.  Perhaps there is nutrient lockout?

Thanks!

If you are really going to spray this often, the dosage should be very light.  Sometimes you could just use seaweed extract/kelp, in your alternating program.  This would guarantee the various trace elements.

elp! What the hack is this? Is this just a super severe iron deficiency? Younger leaves are most affected.

Not an Iron deficiency.

I don't know what it is.  It is very strange to see healthy green at margins and paled out veins.

In Iron deficiency the veins are the last parts to lose their green.

That could be iron deficiency.  What are you fertilizing with?  Looks like it could use a proper fert program, including a good minor element foliar spray. What is the composition of the soil it is in?  It looks like its filled of a lot of rock...

Mario,

Zinc deficiency and Iron deficiency, and probably other deficiencies.  As BSBullie recommends, give it good mixed granular fertilizer plus foliar nutritional spray.

Also do a soil drench with Sequestrene 138 or with Ferrilene.  Use several light doses, a week or two apart, as one can easily cause damage with too much iron.

Thanks for your input, Har. That's what's confusing me too. This year in particular I've been seeing several trees in my neighborhood with that problem. It's also photo-affected; the shaded out portions of the leaf get it less. This morning, Dr Campbell said that he thinks it could be severe iron deficiency. I'm going to go ahead and try an iron drench.

Not an Iron deficiency.

My little Angie definitely needs some micronutrients. Do you think its safe to give it a spritz?  I was thinking of mixing a 1/2 strength batch of chelated micros in a spray bottle.  Yea, nay?

Yea, and a pinch of osmocote will help as well.

If it were me, I'd just give it an osmocote equivalent with minors. Iron doesn't absorb very well through the leaves, so you're better off putting it in the soil (via osmocote). Wouldn't hurt anything to spray though.

Looks like a pine island graft.

Ok cool. I've never used osmocote. I have had some good success with chelated foliars though.  I'll have to look for osmocote w micros.

No idea whose label is on the tree, but I got it a couple of weeks ago from Mike Bender. Coincidently, Mike now works for PIN.  ???

Bonide Iron Drench, has all your minors, applied as a soil drench, along with osmocote granules should perk it right up.
