Whcih mangos would you describe as bulletproof?
Your question has caused me to re-think my use of the word "bulletproof" as it relates to mangoes. I think it would be better to class mangoes by level of resistance.....as I think there may not be a mango that is truly bulletproof. And, what is highly resistant here may not be somewhere else to some disease pathogen that is more prevelent elsewhere or that takes a slightly different form.
That being said, there are many mangoes that enjoy very high resistance to disease here in Florida. And when I use the word resistance, I mean not only that the tree doesn't get the disease at all, but that even if it gets the disease, it still sets a full crop. I think all mangoes have some susceptability to powdery mildew and anthracnose. It just comes with the territory. But, with a nice helathy tree, the more resistant will not be adversley afftected overall.
Most of the SE Asian culivars show very high disease resistance. One that sticks out in my mind is Brahm Kai Mea (or Meu) depending on who you ask and have the name translated by. I think I did a list or responded to a list labelling the relative disease resistance that I have expereinced with various cultivars. Maybe someone has that post from Garden Web......or maybe I can find it and post it here. Of the Indian type mangoes, of course, Tommy Atkins is as resistant as they come. I have only a small token tree grown in a shady spot that barely produces. I have it just to say I have a complete collection. However, my neigbhbors have 7 or 8 trees and they produce faithfully and without any need for spraying beautiful, but unfortunately inferior fruits. I am very impressed with the disease resistance of Pickering and also of Tebow/Young (despite its flavor being overhyped). Carrie and Florigon are some others that do have high resistance here. I am sure I am forgetting a particularly resistant mango or three as I sit here this morning. I'll update later after I check for that list I was referring to.
