The Tropical Fruit Forum

Hi all.  I've read study that yield increased best with 1% foliar applications (compared to .5 or none) and mentioned the sulfur helped fight fungus.

Anyone try this?  I sprayed my big old Kent, no panicles yet, did make leaves nice dark green.
I use copper occasionally when Anthracnose starts getting bad.

Would a drench help as well?

Also wonder if it would help fight powdery mildew or hurt & chase away pollinators?
Sulfur's much harder for me to apply.

Thanks,
Ed

Thank you, i visited website, emailed David & he replied quick.
Tomorrow i'll try taking photo of one for him.  Leaf notcher or sri lanka.
I see how nematodes would be better then Bifen spray if roots are getting munched on.
Light spray of Bifen would stop leaf munching quick though.

Nematodes & chickens oh my! 
Googled nematodes, i have to digest that one a while.  They're tiny.
Chickens would be cool if i had extra time on my hands & ate eggs more often.
Bifenthrin yes 1oz/gal but i'd feel safer 1/4 that.  It's likely used on everything non-organic but i'd feel better using less on food trees.  1oz for ants around house outside yes sir.
Spinosad- haven't tried yet, have it, didn't work very well on citrus leaf minors, only tried once.
Neem oil- looks great on trees at first, but (for me) starts looking dirty for the rest of its life on tree.

Har & Oolie, just want to thank you for replies to my question.  I wrote long reply a month ago but lost it when my failing modem router's wifi cut out.  Had me po'd.  Replaced it since.
The splits on trunk were sticky but not oozing so i let it be.  I think they're ok.

I did see leaves on some after tropical storm winds get mild damage.  Are mango trees subject to wind burn?  Wondered after seeing a previous persons question.

Ed

Careful- i used the natural nuggets from big box store.
Long story short, i raked up all i could & yard is loaded with termites.  Everywhere.
I'll never ever buy them again.  Was used for top dressing all my mango trees.  Disaster.

Har, photos of bark splits taken today.  I applied roughly 2 cups Gypsum each tree before all this good rain.
I really don't want to paint them white, does the paint itself help hold moisture in?  I'd use brown if so.
Also wondering if i painted with Gypsum & water, would it soak in & help soften bark?
I have Neem, oil would soften but might be like baby oil to us.  Thoughts?

Leaf tip burn was from me learning that 1oz of micros per gallon was too much.  1/2oz better, lesson learned.

Thank you,
Ed

Har, i realize a soil test is route i should take before adding manganese sulfate.  Leaves don't show any signs of deficiency of it.  What i have is 32% manganese, 56% sulfate.  A little goes a long way by what i've read.

Calcium deficiency i do have it appears on those young trees, if what i researched is correct.
Trunk bark has tiny cracks as if dry old skin.  Some branches where they attach to trunk look to have crack around them too. I applied gypsum.

Wondering if i mix some with water & paint on with brush, would that help?  Hurt?


Thanks,
Ed

I had similar happen from support stick.  Rubbed trunk, got infected, ng,
Removed stick, cut trunk off below area, was above graft (as yours looks) & grew back.
Orange sherbet.  It's currently in pot cause i didn't expect it to survive & put m4 in its place.

I will never buy another tree without inspecting trunk & remove stick soon as its home.

Yesterday & today looked like hurricane for a few minutes.
Fertilized all my Arecas this morn.  Certainly got watered in lol.
Didn't have time to fert small mangos, bananas & citrus.  Tomorrow.
Making use of the rain.  We needed it.
My Kent has fruit.  If varmints leave it be, i wait till they fall.  Look every morning.  None yet.  Only has 14.  Last yr was triple that.

Would a spray & drench of this help (i know it's late) my Flame grapefruit & Ortanique orange?

Can scions be made from growth between nodes?
Planning on cutting a couple nodes down on some varieties for lower branching.

Ed

My big old tree (Kent) has 2 small mangos hanging on.  Other panicles got hit with mildew & anthracnose except for a few.  Rain made it put out leaves on 3/4 the tree.
This morn I carefully pruned a good 50lbs of branches, another 50-100 to go.
Thinking if I get sun on panicles, they'll be less disease prone.  No idea but might as well before heat comes.

I can't comment on flowering, but read foliar potassium sulfate increased fruit yield in a study or 2.
