It is mainly caused by partial rotting and fruit rot or fruit drop below the sepals, which causes the eggplant to lose its commercial value and cause serious economic losses, and it is difficult to control.

There are "V" lesions on the edges of long gray hairy leaves, wet rot, and gray moldy layer; the top or peduncle of the fruit is rotted and has a gray moldy layer; the stalk rot also has a gray moldy layer.

This is a bacterial soft rot of eggplant, and it is a disease that occurs on eggplant. Control measures: Foliar spraying of agricultural streptomycin, neomycin and so on.
The eggplant is not long hair. It fell from the whole fruit below the respect piece and the fruit fell from below. The fruit peel did not appear rot and remained shiny, but the fruit was found to have turned brown or black after opening the fruit.
