Hi,
I have these same spots on my tiny Pickering, and my young Keitt. There aren’t many but they seem to be increasing slowly with rainy season. The neighbors’ Haden is infested with these spots, but the fruit was clean. I should mention I burned the Pickering with osmocote plus last year.
My house is in north Miami area. 4 miles west of ocean 2 miles west of Biscayne Bay. Sandy soil.
Thank you

Keitt:

Honest Abe,

Do your lawn sprinklers hit your mangos' leaves? It looks like mineral deposits from water.

I think he means the dark spots which look like MBBS. The deposits may be from copper being sprayed?

bsbullie, you are right.

Any help is appreciated. Sad to know that these are acting up as I bought these from a reputable nursery in FL not to long ago...Should've looked at the leaves more closely before buying them.

Honest Abe · « **Reply #1756 on:** September 13, 2020, 10:07:30 PM »

Thank You Guanabanus and BSBullie, I’ve never sprayed them with copper, but the MBBS Is bad news. I’m sad to hear this. Maybe the fruit will be unaffected...I hope.

Guanabanus · « **Reply #1757 on:** September 14, 2020, 08:58:03 AM »

Jaboticaba45,

I am not sure that there is a problem, but maybe the tree is a little low on Zinc and maybe Copper too.

Have you fertilized the tree since you got it? What is the soil like?

HonestAbe,

I have seen several trees with abundant foliar Mango Bacterial Black Spot, which trees never had it on their fruit--- and several trees with infested fruits and clean leaves.

Guanabanus,

They are in the same soil when purchased at the nursery(sand woodchips, etc). One of them I repotted with peat/perlite and I have not fertilized them. Also have a question about anthracnose. How to treat it? I read to spray with copper fungicide...

Guanabanus · « **Reply #1759 on:** September 14, 2020, 01:27:45 PM »

Copper spray is a good preventive of anthracnose infections getting started. Nothing fixes damage already done.

Do give your tree micronutrients, at least.

Thank you Guanabanus!

Iron drenching question-
Is there a general diluted percent of iron in drenching water to shoot for?
Meaning, i could use 5 gallons or 10 gallons 1/2 strength of 5 gallons.
Typical sandy Florida soil.
Thank you.

I dont see any anthracnose on the leaves in that picture. Also, unless the tree came to you with it, not sure you woukd have any issues in Tennessee. If you dont need to, dont spray it.

Most products come with directions on the label. I have never seen a liquid micronutrient product that was intended for use without considerable dilution.

Keyplex 350 is the best.

Please help to ID the issue of my mango leaf.

Guanabanus · « **Reply #1768 on:** September 17, 2020, 07:25:38 PM »

Perhaps deficient in Boron and Potassium--- I am not at all confident about that.

It hasn't been splashed with deck cleaner, has it?

Mango Stein · « **Reply #1769 on:** September 17, 2020, 07:58:10 PM »

This Coconut Cream seedling was fine all winter. Now all of sudden the tips look like they have been painted with black tar. It's in a container still. No other pests on leaves and not near other trees.

Hi Har,

Do you refer to my mango leaf issue? If you do, thank you.

Guanabanus · « **Reply #1771 on:** September 20, 2020, 12:19:34 PM »

Yes, Hoang.

Guanabanus · « **Reply #1772 on:** September 20, 2020, 12:22:54 PM »

Mango Stein,

I would cut off less than an inch of that stem, if the wood at your cut is clean inside, then spray whole plant with Copper and a micro-nutrient mix.

A monthly application on a small mango in a 3-gal. pot: one level teaspoon, well spread over most of the soil surface, but not touching the trunk. Rounded up teaspoon if the plant is over 2 feet tall.

Just realized I (almost) doubled the application of the fertilizer on all my potted mangoes earlier today; mixed it in real well, no possibility of backing it out (I could scoop the top 4" of potting mix out of each pot, but that would be a lot of wasted mix). It's only the second application of this time-released 8-3-9 fertilizer, used fish emulsion and compost tea before this. What do you think I should do now? What do I look for as an indicator that I have a problem? Should I water more or less now?

Thanks!

Guanabanus · « **Reply #1774 on:** September 20, 2020, 07:29:06 PM »

Water more.
