The look of black spot on one of my wrapped durian belanda (soursop) fruit

This is taken in the morning of 20 May 2020. I was in process upgrading the plastic wrapper used to wrap durian belanda (soursop) fruit last 6 April 2020 to larger ones. To my dismay, one of the durian belanda (soursop) fruit has large black spot. Despite my effort wrapping it at earlier stage.

I am still searching for correct prevention and cure steps to curb this condition. Hopefully it will get better after I spray it with wood vinegar.

Till then, have fun in tending after your planted durian belanda (soursop) fruits.
