I have a 15 acres organic farm in the Pacific coast of Nicaragua. I have
over 500 young mango trees (4-5-6 years old).
Many of them have lots of black spots in the trunks,
and on the leaves some of them have little black spots as well.
For what I read, it could be the fungus Alternaria alternataor or the
bacteria Xanthomonas campestr. I have been looking for a
permaculture-organic way to deal to be able to heal my tress, and I can not
find it! Any help PLEASE will be greatly appreciated!!!!
