First report of Gibberella circinata in Uruguay
The presence of Gibberella circinata (anamorph Fusarium circinatum - EPPO A2 List) was reported for the first time in 2009 on Pinus taeda seedlings in nurseries. Needles of affected seedlings showed different stages of chlorosis ranging from pale green to reddish-brown discolouration. Stem and collar rot with bark cracks were detected and in some of them fungal sporodochia were observed. The identity of the fungus was confirmed by morphological and molecular methods. It is suspected that the fungus was introduced with seeds as no symptoms were observed in field plantations. Incidence of the disease in nurseries was low and destruction of all infected seedlings was recommended.
The situation of Gibberella circinata in Uruguay can be described as follows: Present, first reported in 2009 on Pinus taeda seedlings.
