In this symptomatological context, the diagnosis is rather easy to carry out. Indeed, most of the deteriorations observed on fruits are quite characteristic, their origin should, in the majority of cases, be quickly identified (figure 1). It should be noted that certain diseases, whether parasitic or not, only cause symptoms in fruits. Others cause damage to both the fruits and one or more other organs of this nightshade. It will often be interesting to look for them on the plant to confirm your diagnosis.
 
It should be noted that we had difficulty classifying the symptoms observed on fruits and in particular those linked to spots or similar alterations, this from a single criterion. We nonetheless objectively favored the criteria which seemed to us the most relevant to characterize these lesions: sometimes very limited dimensions, a particular location such as the peduncular scar, the presence of patterns such as rings.
