Baby shampoo has a different wetting agent than dish soap.

Bovine,
Sap flow in night shot is perhaps from a mechanical injury or bite, or from a deficiency of Copper. Spray Copper.

I just noticed there's another battle going on the Battle of soursop I notice a lot of little dead looking scales then webs. I've also noticed them on the battle of sooty mold.

I will not show this to my wife she has arachnia phobia

Specific spray formula against Powdery Mildew, using Sulfur, Copper Soap, and Kelp. Only good with spray equipment having a good motorized agitator.

Thank you Har (and Chris) for another great informative video. Timely too.

Update on the Battle of sooty mold
Over the weekend I observed that the WASP have lost interest in my honey kiss mango tree
Per your advice I purchased a half gallon pressure sprayer and concentrated bonide neem oil. I sprayed the underneath side thoroughly the trunk all branches then topside looking down
Honeykiss has shown no signs of pushing flowers even though in the month of December we only had a handful of days above 59 degrees at night. Neelam is the only other hold out and that's all I'm going to say because of mangostition .

Har, i viewed Chris' Jan 2020 blooms & fruitsets video. Excellent, thank you all.

What did you learn & what will you (if any) try differently?

Does watering effect fruit set?
Would nutrient drench effect fruit set?
Would a low pH vit c spray fight molds?
How low of a pH can leaves handle?

Hi all. I've been following this thread for a long time. Lot's of very good info here so thanks to all for this Mango Culture 101 course. My question is related to potassium bicarbonate. I have used this with great success as a foliar prophylactic treatment for fungus and as a nutritional supplement in the past on my mango trees...but not during flowering. Is there any harm in spraying K bicarbonate on mango inflorescences?

Guanabanus · « **Reply #1883 on:** January 06, 2021, 09:42:53 PM »

Should be O.K. on emerging spikes, but I haven't used it on open flowers.

Keysbob · « **Reply #1884 on:** January 07, 2021, 08:12:25 AM »

Thanks Har. I think I will try at 1/4 to 1/2 strength on a few flowering panicles. If I were a betting man, I would guess it will be no problem and could even be nutritionally beneficial. We shall see.

EddieF · « **Reply #1885 on:** January 12, 2021, 04:34:47 PM »

Happy to see these starting & look realitively clean for dense privacy hedge & my guess Kent.
Is it ok to continue copper on all but the longest ones? I switched to little squirt bottle so i can selectively spray.

Thanks as always,
Ed

All pictured spikes are still sprayable with Copper.

EddieF · « **Reply #1887 on:** January 12, 2021, 05:15:46 PM »

Thank you Har, trying my hardest this yr. I'm gaining weight watching your great tasting table videos. Inspirational.

EddieF · « **Reply #1888 on:** January 12, 2021, 10:02:36 PM »

Continue copper as needed till flower(s) open...

switch to sulfur on open flowers to protect,

pea or bb size mangos resume copper & nutrition.

Sound good? I've been watering almost daily since i tossed a few lbs of fert & some calcium & potassium.
I cut at least 10 garbage pails off that tree every year. Been double that height 10yrs ago.

What could this be in my mango leaf? Some have it, others dont.

Guanabanus · « **Reply #1890 on:** January 14, 2021, 07:42:10 PM »

Eddie F., Have you seen a recommendation to spray Sulfur on Open Bloom? I don't remember if I have tried that.

EddieF · « **Reply #1891 on:** January 14, 2021, 08:09:11 PM »

Har, i thought i saw a video (not yours) that suggested it but, i've almost killed bananas doing what i read in reviews (not here) as well. If you don't spray blooms with sulfur, i surely won't.
Powdery mildew hits this tree hard every year. I'll do whatever you suggest. Tree's looking very good preparing for bloom now that i'm staying on it with copper, 3 not 4 tsp. Hoping i won't get tree in trouble using weaker more often. I don't mind, easy enough.

Guanabanus · « **Reply #1892 on:** January 15, 2021, 03:14:41 PM »

I certainly do spray Bloom Spikes with Sulfur, but one has to be very careful with fully open flowers. If you try on just a few and they look good a few hours or a day later, and then set fruit, then you know your mix was a good one to use.

EddieF · « **Reply #1893 on:** January 15, 2021, 08:00:20 PM »

Thanks Har good to know & i will. I sprayed copper yesterday (1oz on that whole tree) which was 1 tsp/gallon shy of spec which seems strong enough. No flowers yet.

How many days should i plan to wait before switching from copper to sulfur?
And when is latest i should apply sulfur? My guess soon as flowers begin to open to avoid hurting pollen.
I take it my job is to have sulfur on pentacles right before bloom so the sulfur protects hopefully till fruit sets.

Thanks again, i'm sure others are gaining knowledge from this.
I really do love these mangos. Drops are all i ever eat, my favorite. I get out early & check ground for them before ants do heh. It's the perfect ripeness.

EddieF · « **Reply #1894 on:** January 16, 2021, 06:08:12 PM »

Photos today. Mixed copper but too windy to spray. Panicles not shown have black spots & see it on buds too. Should i hit it with copper 1 more time or switch to sulfur? Thank you.

South east side has the action.

Guanabanus · « **Reply #1895 on:** January 16, 2021, 09:41:55 PM »

Copper.

Please, can someone guide me in the right direction with my mango tree?

Guanabanus · « **Reply #1897 on:** January 20, 2021, 07:14:06 PM »

Probably the leaf form of Mango Bacterial Leaf Spot. Spraying with Copper will slow the spread of the infection.

EddieF · « **Reply #1898 on:** January 21, 2021, 10:30:38 PM »

Update-

So far so good, copper whole tree 1oz or less, every few days it seems.
Panicles are facing east south east.
Anthracnose on dark north side been there 10yrs, i personally enjoy privacy just as much there.

Thank you Har.

Hey all, first post in here as I finally got some mango trees! Two weeks ago I drove over to West Palm and picked up several trees which I hauled back in an enclosed trailer. All are 25 gallon size trees aside from one 15. Two Maha Chanok, two orange sherbet, a lemon zest, a NDM4, a VP, and an Edward were our choices based on having tasted and liked all of these several times. we are not ready with our yard yet to plant them in the ground so they are going to stay in containers probably until mid-summer. They are getting full sun now. Straddling 9b/10a in Sarasota. Some of them look great, some of them look a little pale and droopy. Hopefully over the course of the next couple weeks with the help of this forum I can get up to speed on a proper spraying and feeding regimen. I've watched as many truly tropical videos as I can and have been researching and trying to absorb as much as I can.
Lets start with my Orange Sherbet - it has several burnt or dead looking leaf tips and some of the older lower leaves look a little pale. I have not fed or sprayed anything yet on this tree, just gave it water once after transport as the soil felt bone dry as far as my fingers could reach. If any of you folks could offer some advice on what deficiencies I might have, and a proper feeding/spraying/watering regimen for this time of year and stage in the plant's life that would be fantastic!
