Jackfruit disease.. turning the fruit black, soursop also has black disease, and

[Capt Ram]

I have  an Excalibur red jackfruit tree that's mature and this year three of the fruit have turned black..
The only difference this year is I stopped watering it..
Could this be some kind of disease like bacterial black
spot that we're getting on mangos?
I also have the seemingly same issue going on with one of my mango trees and  soursop, along with sugar apple

[Shiapouf]

looks like black rot to me, especially if the same thing is happening to all your other fruit

I have that on my Soursop as well. The fruits grow and then fall before they are mature, all black. Is it anthracnose?
