Plant Doctor is not an oil product.  Perhaps you are thinking of "Organocide 3-in-1".

No I'm just saying I have not used any oil products on these trees recently but I did spray potassium bicarb yesterday morning. The question is how long do I need to wait before spraying the copper soap/sulfur?

Looks like fungus starting to show up on our Carrie, Edward and Coconut Cream. Powdery mildew, Anthracnose, something else? SE Florida zone 10a.
I sprayed potassium bicarbonate (Green Cure) about a week ago at first sign of disease.
Next will be copper soap and micronized sulfur.











In the first two pictures, I have seen that look on Coco Creams grown in pots with poor airflow at nurseries.

What do you suspect it is Rob?

Not sure.  I would say a fungus of some type but it not only causes the spots but causes curling and deformation of tff he leaves.  I would look toward a systemic fungicide, perhaps Abound if you can get it.

I doubt copper is going to tackle the issues on the Coco Cream.  See my message above regarding Abound.

If its not PM, why bother with the sulfur.  Less is more when applying chemicals.

Look on or under leaves for scale or aphids.

Labels normally contain information about intervals between spraying the label's product and products that are super common, if there is a known issue.

Hey Guys, so whatís my 1.5 year old VP telling me is wrong? Starting seeing this about 3 weeks ago. I sprayed southern AG Foliar spray for citrus, advocation, mango just two days ago to try to correct micronutrient deficiency. Seems within last 2 days things have gotten worse. What do you think this is and What do you recommend to correct the issue?

Fishingsteeg,

Possibly MangoBacterialBlackSpot, but could be a fungus.  For either one, spray Copper products, to reduce the spread.

Mangoba,

The only thing I see out of kilter is low Manganese--- it should be equal to or greater than Iron.  Could also be low Sulfur.

Please help rescue my new mango! This is a Triple Sec/ Seacrest. Last week it arrived healthy after 3 days shipping from Florida. It was wrapped with its soil(pic 1). I put it in a 5 gallon pot with fast drain potting soil temporarily before plant it in the ground. Slowly the leaves turn yellow, and the leaves drop one by one. The other 2 trees are not experiencing this. I water everyday because I thought it is okay with the fast drain soil. The water goes out immidiately from the bottom.
What did I do wrong? Too much water? Any fungus root maybe? Should I repot it soon? The tree was under the full shade before, but I moved it to get about 2 hours sun now to dry the soil in case of overwatering.
Thank you for any advice.

Three-days'-shipping in total darkness is hard on trees--- they start to starve--- then it went into "total shade"--- more starvation.  The only food plants have is glucose from Photosynthesis.

Thanks, Har. I moved it to a sunny location. Hopefully it will recover soon.

From my experience, trees shipped from Florida by ground without pot takes 6-12 months to recover. That is if it doesnít die during winter. Trees shipped with pot fare much better but still takes at least 3 months to recover.

That always pissed me off when they shook off half the dirt and wrapped them without a pot.  Totally ruins the tree doing that to them.  Its even worse on lychee trees. 

Better to just grow seedlings and graft them yourself.  And way cheaper.

Are these bottom leaves from rootstock? do they look like turpentine mango leaves?

Not Turpentine leaves.

Spray with Copper and other micro-nutrients.

does this look ok? Since this is a grafted tree, I assume that this is turpentine. Is this rot? if so what should I do? Thanks
