In SW Haiti, we are seeing slow death of young Soursop trees in full sun conditions. Irrigation is available but the trees die slowly. I read where phytophthora root rot may be a cause but one source says too much water and another source says too dry causes the disease. Any ideas?

Je voulais vous répondre à cette question, le problème avec ton arbre et qu’il souffre d’une maladie d’origine abiotique. C’est à dire une maladie non parasitaire. En plus d’être une maladie non parasitaire je peux vous rappeler la petite notion de la Phytiatrie ( Science qui traite des maladies des plantes) qui dit: plante+ condition non adaptée = maladie.
Thank you for your response. Yes, it is a possibility of a cultural problem. The trees are not in waterlogged or poorly drained soils which could cause phytophthora root rots. What other cultural factors would cause the decline? Of note that soursop trees growing in shade are surviving but fruits won’t ripen and there is much etiolation as a result of shade.
I think this is a general problem with soursop plant. After two to three years they are attacked by disease and die off. I am interested in this also
We find that the ones in the sun die quickly so the PHF team will be planting a row of small trees for shading the Soursop.
The leucanea is the tree we will be Alley cropping with the soursop. Its a legume and available in sw Haiti
