PRESENCE OF THE QUARANTINE FUNGUS Fusarium
Circinatum ON PINES IN GALICIA.
Fusarium circinatum is the anamorph of
Gibberella circinata Niremberg & O´Donnell. It affects several
species of the genus Pinus, among them Pinus pinaster and
Pinus radiata, which are very abundant in Galicia. The fungus was found
both on young and adult plants, causing weakening and death of plants if damage
is severe. On adult trees, the disease is known as 'Pitch Canker' and has a
strongly infective action both on vegetative and reproductive tissues, among
It is a quarantine
fungal pathogen included in the A2 EPPO (European Plant Protection
Organization) Action list. Since its presence was not confirmed in the European
Union, the Spanish Ministry of Agriculture, Fisheries and Food issued the Royal
Decree 637/2006, of 26 may, establishing the guidelines of the national
programme of eradication and control of the fungus Fusarium circinatum.
In Galicia this fungus was first
detected at the laboratories of the Estación Fitopatolóxica do
Areeiro at the end of 2004, first on young plants from nursery, and
subsequently also on adult plants. This laboratory is following the recommended
protocols of the Royal Decree 637/2006 to determine their fungal structures:
mono and poly- phialides, macro and microconidia, and circinus.
