Many small black spots appear around the fruit pedicel

by Mr. Wangzhixun, MinQing, Fuzhou, China

Question

In open field production in MinQing (China) many small black spots appear around the fruit pedicel on the majority of fruits. It appears in all varieties in my field. This happens when the fruits are changing color from green to red. The fruit’s skin becomes rough and the coloring is uneven. This phenomenon affects fruit quality and might result in sale loss. Can you please tell me what the cause for this phenomenon is and what are the best ways to avoid it

In my opinion the black spots resulted from physical damage – either hail or snow during early fruit development. All the spots appear only on one side (outside) of the fruit and in all the varieties. It seems that the damage occurred at an earlier stage, but only becomes visible now, that the fruit is larger. I do not think that it has anything to do with the color change that probably resulted from unbalanced fertilization.
