Fusarium circinatum Nirenberg et O'Donnell (telemorph: Gibberella circinata Nirenberg et O'Donnell) is a quarantine organism in Europe producing the disease known as pitch canker of pines. For a decade, the European Union has taken steps to locate and eradicate the pathogen with the aim of eliminating the risk of spread. So far, research has focused on forest stands, however, the movement of felled timber may pose a threat from its cutting at sawmills until its transformation at its final destination. This paper presents the current research progress in this line, evaluating the efficacy against Spanish isolates of F. circinatum of the most frequently anti blue-stain fungi products in green wood of four of pine species (Pinus sylvestris, P. pinaster, P. radiata and P. nigra). The results show that the only product which contains a high percentage of propiconazole, together with tebuconazole and 3-iodo-2-propynyl butylcarbamate (IPBC) is effective. This fact should be taken into account in the wood protection industry, as it would be the best preventive measure to ensure the control of this organism, preventing the implementation of ISPM 15 which is currently applied but does not guarantee its elimination.
