Symptoms on tomato  


  • Organs attacked  :
Leaves flowers
Fruits rods
  • Symptoms :
    • Plant growth often slowed, with shorter internodal apices and smaller, sometimes rolled leaves. Plants infected early have a rather bushy habit, partly linked to the development of numerous axillaries (figures 1 and 2).
    • Deformed and discolored leaves: more or less yellow (yellows) and/or purplish (anthocyanin) (figures 3 and 4). Leaf blade often thicker, even brittle.
    • Sometimes presence of adventitious roots on the stems.
    • Abnormally straightened flowers, often sterile with morphological aberrations (figures 5 and 6):
      • the sepals, whose veins take on a purplish color, remain completely joined and the calyx is hypertrophied (big bud);
      • the flowers are sterile and the petals are green, with stamens of the same color (loss of floral pigment, virescence);
      • the sepals may be leaf-like (phyllody); we can also note the malformation or the absence of petals, stamens and carpels, the hyperdevelopment of the petioles, etc. ;
    • Rare fruits with reduced growth, hard coloring slowly and irregularly and having a rather thick peduncle contrasting with their reduced size fruits.
  • Signs  : no visible signs, confirm the possible presence of vectors.
  • Possible confusion : herbicide phytotoxicity, TYLCV type virus, etc.
  • Production areas affected :
New Caledonia 
  • Phytoplasmas reported on tomato :
  • Candidatus Phytoplasma asteris (16SrI-B)
  • Candidatus Phytoplasma aurantifolia (16SrII-B)
  • Candidatus Phytoplasma trifolii (16SrVI-A)
  • Candidatus Phytoplasma solani (16SrXII-A)
