Interesting, I've noted in the past that certain trees seem resistant for some but not for others, and this is more evidence to that end.

Mallika is highly prone to bacterial black spot and lost most of the fruit to it

Alex has also stated that Maha has similar issues in his grove.

Also CM has noted that some Keitt trees are sensitive to MBBS while others seem less affected.

Seems like there's a factor involved that needs further investigation.

I have never had issues with Maha and Mallika in my yard; both trees are productive and the fruits look really clean.  Mallika is however hard to pick at the right time.

Did you mean Pickering?  Pinkerton is an avocado.  Is there a Pinkerton mango also?
Thanks John, I did mean to Pickering

I believe Alex told me Maha Chanok gets MBBS.

The factor is that those trees havenít been infected by the pathogen yet or had levels build up to the point that high numbers of fruit are infected. If you were to inoculate an Uni-nfected Keitt tree and allow for favorable conditions (namely wet weather), the fruit would start being affected.

Itís no different within our own orchard. We had trees of the same variety that were badly impacted and the same cultivar a few hundred yards away was fine. Then a couple years later they werenít.

I don't know of any variety which is "immune" to MBBS; likely all varieties are affected by it, at least when the fruits' skin is rubbing against another fruit or against a branch.

So I agree with the original poster's wording, that we are looking for "resistant" varieties.

Yah, oddly the keitt 20 feet away from the infected keitt never had a problem with MBBS. The infected keitt, after having near total crop loss for several years, has been relatively disease free for the past 2 crops. I think my spray regimen is working.

None of the three Mallika trees, widely separated from each other at Truly Tropical, have shown any particular weakness to MBBS.  I should have included it on my apparently resistant list.

We just don't know much about what the factors are that are at work here.

One of my customers has a Mallika thatís been getting wiped out by it for years. So thatís two Mallika trees Iím aware of getting it bad. Thatís enough evidence for me to say itís probably prone and at a minimum shouldnít be declared resistant.

Totally agree with the fruit rubbing aspect from observation, as a test I am taking my heavy fruiting Hatcher (this year) and separating any fruit that rubs against each other or a branch, leaf. Years past I noticed multiple fruits that touched never saw a knife. Who knows maybe when all the fruit count is lower I will get some of those jumbo fruit that grow on the hill.

I definitely think there can be a prophylactic effect from spraying with regard to mbbs.

Is MBBS just a South Fl disease or also found in the Northern parts (namely the panhandle)?

Also, how does Ataulfo/champagne/honey mango fare to MBBS?

Probably not enough mango trees in the panhandle for it to be a problem there.

Our Ataulfo tree doesnít get it, but there arenít many Ataulfos in south Florida to compare notes on.

HA thatís funny. Trying to grow some dwarfs up here, and Iíll be piling leaves around em when it gets under 25F. Got quite a few ataulfos going from seed too. Fortunately theyíre polyembryonic.. still gonna take some time to produce though. My largest one is about 7 ft. Froze to the ground 2 or 3 winters ago but came back. Just hoping climate change will warm the winter lows up 2 or 3 degrees.

So are mangos the only species that harbor MBBS or can it be transmitted through native flora too?

Unknown.  Seems unlikely.

Your young mangos will be frozen to death at temperatures way above 25-degreesF.!  Trees with trunks a foot in diameter can survive an hour or so of that, with severe branch damage.

Hmm.. not sure if its just the coastal microclimate I've been growing mangos in or not, or maybe it's the varieties I have been growing (seedling Kents and Ataulfos), but the only time I had all my seedling mangos freeze to the ground was when it got down to 19F a few years ago. I've had multiple 6-inch seedlings endure 23 degree outside temps with just tip burn and some half-burnt leaves. Although maybe two degrees colder and they would've burnt down completely.. Every winter we get about 10-15 frosts (usually mild and pretty brief, maybe less than 4 hours below freezing for each frost, and the coldest ones only got to 27F), but had absolutely no observable damage on any mango the past couple years.. including the first cold front of the season where it dropped from about 80F to 40F in 5 hours. I found it interesting that many seedling lychees and carambola were leaf-damaged in that event, but none of the seedling longans or mangos were affected. Even the seedling cherimoya/atemoyas had leaf burn. Real strange..
Perhaps grafted mangos react a bit differently to cold temps than seedlings..
