Symptoms of Verticillium dahliae on eggplant

Verticillium dahliae mainly attacks the vascular system of plants, but symptoms are also on the leaves.

  • Premature death of the leaves, leaving the fruits exposed to the sun.
  • More or less marked browning of the vessels of the lower part of the stem extending over time and reaching the branches.
  • Weakening of plants or even premature death, reduction in yields.
