Thank you everyone for your suggestions. I might be wrong, but I think my pomegranate are probably not infected with Alternaria Fruit Rot or Aspergillus Fruit Rot because I have looked at pictures of infected fruit using Google Images, and it showed lots of pictures of leaves which had spots all over them, but my leaves are fine without absolutely no spots at all. The spots are only on the fruit, not on the leaves or the bark.
Tiger, in your pictures, I can see that the rot in your fruit covers only a patch of the fruit, not the whole fruit. Also, you said that the rot starts at the bottom and works its way up. That’s different than my problem because for me, the brown spots are all over the surface of the fruit, and they aren’t in “patches” like they are on your fruit.
Ross, maybe you are right that my pomegranates are Gainey Sweet because the fruit which is in the picture at that website looks similar to my fruit.
Here is a picture of Gainey Sweet pomegranate:
When I cut open my fruit, I’ve noticed that even though the skin of the fruit is covered with brown dots, there are no brown areas at all inside the fruit, so maybe there isn’t really a fungal infection like I originally thought.
I’ll wait about a month for the fruit to get ripe, and then I’ll post new pictures at the forum here so you-all can see what the fruit looks like when it’s ripe. (However, I’ve already picked most of the fruit because I thought it was infected, so unfortunately, there won’t be much fruit left to pick a month later.)
