Mango is dropping leaves

It doesn't look like the anthracnose pictures in the link. These spots are only on the underneath side of the leaf. The new leaves are wilted like they need water, so I did water it good this afternoon.

Hi Rachele, The closed up view says it might be associated with Bacterial Black Spot of Mango. What is your mind now? Can you pls ck in Plantix Library by clicking on green hyperlink and compare?

Hey guys! Leaves are pointed downwards because of a lack of mineral salts and isotonic/osmotic balance within the leaves. Just like a human being, plants need electrolytes and salts too! = ) The mango leaves of our plant were always curled and never seamed to point upright, but what worked for us was to add a tablespoon of organic black strap molasses (fertilizer) and a teaspoon of sea salt to a gallon of water (trace elements) and to give that to her on a weekly basis. That should give her vigor. = )

Hello Dean Simmons, These black sooty appearance and rolled or wavy fatigue are due to the stress on breaking of plant metabolism. The causal agent in a bacteria that is not supposed to be corrected by adding sea salt. Thanks for you points and insights :)

Sali I have treated it twice already with Copper Oxychloride. Will it hurt it to treat it a third time? The drooping and leaf drop started a couple of weeks after I treated it. Would it hurt to also try the molasses and sea salt?

You can try molasses and sea salt. However, please remove the severely affected leaves so that the pathogen can not transmit to healthy leaves by insects movement. I should suggest to wash out the leaves carefully both sides of the leaves and spray then some micro-nutrient for rapid recovery.

I've about 60 mango seedlings and I washed out the sucking insects like Mealybug today. I may send few pictures. Best :)

Sali all of the old leaves have the tiny black spots. You want me to pick them all off? And then spray micro-nutrients on the new growth?

Rachele Absolutely right you are!!

Ah, I thought I was looking at two plants in the photo! Your mango tree is very big! 😄 Did you have a frost by any chance? 🤔 Each soil has such unique properties in nutrients and trace minerals that it's hard to pin down the exact cause of their behaviors, but it could help us if we had more pictures of your plant for a closer look at her leaves. If we can identify and treat the root cause of the symptoms, we can prepare them from manifesting again. 🌱
