Mango Pests, Diseases, and Nutritional Problems

[Guanabanus]

Your trees look fine.  Those bottom leaves are at the end of their lives.  Only recognizable symptom on those older leaves is Manganese deficiency, but what they have, including Nitrogen, is being pulled out to re-use elsewhere.

Thank you, Har, that is reassuring.  Being that this is in a container, what do you recommend as far as watering this time of year?
Especially in containers, there doesn't seem to be a lot of consistent information I can find about proper feeding and or spraying regimens for the winter. Some people say  dont water, feed, or do anything...but especially in a container that feels risky to me. My goal is to have a healthy tree that is ready to go in the ground this summer... I'm not really concerned about fruit. What's the right approach?

Water containers every couple of days in Winter, unless the soil is still wet looking.  Dailly when warm and windy.

Been a few days since copper.  Wondering if it's sulfur time for panicles while i selectively spray copper on north side with anthracnose & buds that haven't started panicles yet.
I also have kelp, would a drench or foliar be benificial now?

Thank you,
Ed

All good ideas.

Someone on another forum asked what was wrong with their mango seedling, can you help her?

[Guanabanus]

Cut top off, down to where the plant is clean.  Don't use compost or high-nitrogen fertilizer.

Thanks! So is this not a disease but overfeeding?

[Guanabanus]

Over-feeding Nitrogen increases susceptibility to pests and disease.

After pruning, spray several times with insecticidal soap, and separate times with Copper.  Follow label instructions.

OK, thank you very much!

Photos today.
I haven't sprayed sulfur yet cause they look so pretty.
Since last post, i did a little kelp drench (no foliar) and sprayed non bloom areas with copper.
Am i asking for trouble not spraying sulfur on blooms?  Thank you.

Get yourself a moisture reader so you’ll know exactly when to water.

Hey everyone first time posting in this thread. So just got this plant in the mail minutes ago and was wondering what these black spots are on on my Coconut Cream. Im looking back through the thread and i assume its anthracnose or black spot, duh? How would i go about treating this? Thanks

Unfortunately I have some mango trees that are pretty susceptible to anthracnose. I want to use Organocide Plant Doctor this year due to the systemic action, as well as its ability to fertilize the tree and encourage more blooms, if I am reading it right. The trees are just starting to bud where the panicles will be, however the instructions say to spray during the blossom period. Would there be any benefit or harm to start spraying them now? I want to give them a good head start if I can. I emailed the company about a week ago and haven't heard back. Thanks!

[Guanabanus]

Your trees ARE in the blossom period.

Thanks for clarifying Har, I thought that meant when the panicles were actually mature and the blooms were visible rather than the green buds that are just starting to come out on my trees (they seem a bit late this year). I will get spraying then. Thank you.

Hey everyone! I just picked up this coconut cream from TT two weeks ago. Has about 12 small fruit on it. Most of which will probably fall though I do hope it holds some. The leaves have black spots and it since I got it home they seem to be getting worse. I have a few other mango trees that look clean and would like to get this one looking the same. I haven’t put it in the ground yet because I don’t want to shock it and have the hopes of some fruit fall to the ground. Please let me know if this is anthracnose or black spot or what? And what to do. Thanks!

[Guanabanus]

Spray with A Copper product.

[Corey_Mango]

Thanks Har. How many times how often? Is there something else other than copper? I read it can harm the good bugs. I can bring this plant out into the street to spray because it is still in the pot if I had to I guess. Thanks!

[Corey_Mango]

Har is this anthracnose or mango bacterial black spot? What’s the difference?

[Guanabanus]

Follow label.

One is a fungal disease and one is bacterial.  Let Google be your friend...

One of my trees is pushing out panicles that have a "sooty" blackish tint to them, see below. All the panicles on the tree look similar to this (even when just emerging), but the Sweet tart at the same stage of panicles right next to it (within a foot or so of each other's branches on one side) is clean with no soot whatsoever (second pic). The parent tree I took the scions from had a very similar look at it's earlier stage of budding, but is loaded with healthy flowers now. Is this an issue that needs correcting?

[Guanabanus]

Probably fine.  Different varieties have flowers of different colorations. 

[JakeFruit]

That's a relief to read, thanks Har.
