Symptoms on Solanaceae

• Organs attacked :

•  Symptoms : 
  • Moist, brown lesions extending inside the stem, in the pith which liquefies rather quickly, and eventually hollows out (figures 1 and 2).
  • Longitudinal alteration of the stem which takes on a dark brown to black color and can be girdled over several centimeters (figure 3).
  • Note that decomposing tissues are moist and soft (Figure 4).
  • Yellowing and more or less marked withering of the leaves, evolving or not towards the death of the plants.
  • Wet,  viscous and soft rot on fruits leading to their total liquefaction.
