Tonyma,
Perhaps a burn from spray in very hot sun, or from pee, from a pet or tree frog....

27
I prefer to pollinate female-stage flowers on a tree when that tree's male-stage flowers are shedding pollen, or within the next couple of hours, or at the latest, when the male-stage flowers are dropping petals, which is when it would be natural for freshly exposed beetles covered with pollen to go seek out a female-stage flower to shelter in.

If you pollinate apparently female-stage flowers later than that, there may not be any remaining receptivity, especially in dry weather.

28
One should list first the seed parent, which is also known as the mother tree:  in other words, the tree with the flower into which you stuff pollen.
Then X.
Then pollen parent.

Cherilata varieties are:  Annona cherimola variety X Annona reticulata variety.  If it were the other way around, it would be a Retimoya.

Impressive!

31
Dead tissue, from previous infections or spray burns.

32
Healing will take over one year.

I don't know that product.

33
Spray it several times with Copper products.  Then the tree's bark will probably heal over that spot.

34
JakeFruit,
Spot spray with hydrogen peroxide till ooze dissolves, wip off with papertowel, spray again.  While still freshly open, spray whole tree and wounds with any Copper Sulfate Pentahydrate product.  If you only have Copper Octanoate or Ammoniated Copper, those will also work.

35
Jagmanjoe,
Wind damage followed by fungus infections: Anthracnose, and probably also Cylindrocladium.

3rd picture:  mineral deficiencies--- Zinc, and probably Copper and Sulfur.

36
I had been asked about those pictures earlier, and I was stumped.

Thank you, Fleep!

37
Ants transport the young of pests.

38
Castor Bean is a source of Ricin, a deadly poison.

Remember the crazy religious cult in Japan, and their attack in the subway system with ricin?

I would check and double check that castor oil is free of ricin, and that the oil is allowed on what you are thinking of using it on.

39
Sprays usually don't fix damage already done--- no resurrection of dead tissue.

40
Tonyma,

Probably Mango Bacterial Black Spot.  Or Anthracnose.  For either, spray with any Copper product.

41
Calusa,

Deficiencies of Zinc and Copper.

42
Malhar,
deficiencies of Zinc, Manganese, Copper, and Potassium.

43
Victoria Ave,

Better-spreading irrigation at the surface, and the shadecloth, would indeed both help.

You didn't mean to say 42-gallons on one plant, did you?

Shading / windbraking the planter box sides, with burlap or with potted plants, would also provide some relief.

I didn't see mention of a substantial source of Calcium.

44
Nicely detailed soil report.  Manganese is low in relation to amount of Iron--- should be similar amounts.

Plant looks good.

45
Victoria Ave,

A Valencia Pride that doesn't produce vegetative flushes for several years?  Very unusual!

What type of soil is it growing in?  Types of fertilizer?  Source of Calcium?  Frequency and amount of water?  Weather?

46
Nuraxi,

Looks complicated.

I recommend that you get a soil analysis and a leaf tissue analysis, testing for all the known plant nutrients, in each sample, including Sodium (Na) and Chloride.

47
Jose',
Probably cold-soil-induced deficiencies, of Calcium, Sulfur, Zinc, Iron, etc.  Red spots may be from thrips or from micro-mites.

48
Seedlings of pure sugar-apple, pure custard-apple, pure ilama, or pure soursop, are usually just as good as, or almost as good as, the mother tree.  Some indeed are worse.  Or take longer to fruit.  [pure = non-hybridized]

Seeds from hybrids can be wildly different.




49
I don't know anything about Annonas in relation to nematodes.

50
Perhaps hydrogen peroxide, diluted to 0.25%.  One and a half to two gallons of mix poured onto one square foot of the soil.  Weekly, until corrected.

Example:  11 pints of water (same as 1 gallon + 1 quart + 1/2 quart) plus 1 pint of drugstore 3% hydrogen peroxide.

If you buy a concentrate somewhere, remember that the concentrate can cause immediate blindness if it splashes in your eyes,
severe skin burns, or holes in your cotton clothes.
