This new vendor (for me) has some great prices.  Am working up a cart with to include a hard to find Mycho called VAM and getting Peter's S.T.E.M.   They have silicates.

Should I pick any scab affected mangos off the tree while there small?

Your sprays are probably working well enough to prevent spreading.

I am going out of town for about 8 months during the warm/hot season. Last year on my mangoes we had bad weevil infestations as the primary bad guy affecting mine and my neighbor's mangoes and a few other trees. Hoping this continually cold weather will kill a bunch of those off, still 33 in the morning here in east Orlando. My in ground mangoes are recovering from the hard freezes of this year and have only recently sprouted new leaves mostly from the trunks. What kind of long term root drench can I use before I leave to kill off any weevils in the ground? Preferably something I can get off amazon or ebay.

I suspect leafhopper/ sharpshooter or brown stink bug that got into this branch.

I hope Iím not sounding too dumb or going off subject.
Reference to the #1 treatment of mango trees a few weeks ago when they were all blossoming and how to get the highest yield by preventing powdery mildew and anthracnose on the new growth and flowers.
Last year at a Miami Rare Fruit council lecture on mango diseases a Dr McMillan who is a very published plant pathologist probably in his mid to upper 80ís gave us the bottom line from all the research projects done on this topic.
Abound plus New-Film 17 gave the best results by far. No contest.

Yes, that is definitely a great conventional treatment.  Remember to alternate with some very different product, to avoid breeding resistance to Abound.

Abound is going to become worthless at the rate people are using it these days.

Switch and / or a copper-based fungicide are great alternators for Abound.

I think commercial growers represent the biggest risk to group 11 resistance. Dooryard growers are unlikely to spend the time and money on a comprehensive fungicide routine, at least not on a regular basis.

And I still haven't heard of a recommended treatment protocol for Mango Bacterial Black Spot specifically.  So it's just muddling along with Copper products and other products labeled for other bacteria.

Though one column of that chart is dedicated to "bacterial black spot", the text contains no mention of it, and there is no picture.

The text describes anthracnose spots on leaves as "angular", which seems to have been more associated with bacterial black spot in illustrations I've seen from abroad.

The designation of 'Florigon' as highly susceptible to bacterial black spot is probably a typo--- like the spelling of 'Nam Doc Mai' as "Man dok Mai".  I believe 'Florigon' is highly resistant.

Given the year that PDF was published, I'm guessing that they are referring to the BBS that infects leaves (not the new variant which infects fruits).

The website states that you can get it at HD, but HD only carries a different product then the one shown on the vendor website. The HD version is a combo product that is not shown in the vendor website.

Do you have a HD sku number for the Organocideô Plant Doctor?


The sku is on this http://www.organiclabs.com/Images/LabelImages/Plant%20Doctor%20Back%20Label%20Booklet%20Instructions%20for%20Use.pdf
It is at the Home Depot in Jupiter and you can also find it online at Ebay. 
It clears up Anthracnose faster and better than anything I have ever used.



How much liquid do you use per gallon of Plant Doctor?

I was wondering how much has changed since it was published.

Organocide Plant Doctor is a registered pesticide, so you must follow the label.

There are other phosphites that are labeled as fertilizer....

Hello,

I'm almost afraid to ask this.  I notice a couple of my leaves on my Sweet Tart have black blemishes.  There's really only 1 leaf that has a lot of it.  I'm afraid it's bacterial black spot, but I'm not sure.  Sweet Tart is my favorite mango, and I'd be extremely sad if it's BBS, especially considering I bought the tree last year as a 7 gallon and haven't even had 1 fruit from it.  Other than the couple of leaves, the tree looks pretty healthy to me.  Should I be concerned or is it nothing?

Itís bacterial spot. At least the foliar form of it. Not a big deal unless you also have the strain that attacks the fruit.

Remove those infected leaves, since there are so few, and it is so easy to do.  Discard in city trash.

Thanks Alex and Har.  So I guess at this point I just need to wait to see if the fruit develops it too.  What are the odds my fruit would have BBS considering the tree has foliar BBS?
