I have a Baileys Marvel mango that is approx. 3 years old...one year in my yard.
At times, it has lots of new growth...but after about a week, the buds/leaves/new growth begin to turn black, then shrivel up and die.
I've included 4 pics showing the various stages of the new growths "demise".
Following the advice of a gardening center, I've applied 3 doses of Dithane-M45 (once a week for three weeks)...and things seem to clear up.
This happens every time there is a new flush of growth...not ALL of the new growth dies off, probably 30% dies, but the rest remains healthy looking.
Any suggestions or assistance would be greatly appreciated!
