Abstract(s)
Fusarium circinatum is one of the many threats to forests and Pinus nurseries all over the
world, being classified as a quarantine organism by several organizations and governing bodies, such
as the European and Mediterranean Plant Protection Organization (EPPO) and the European Union
(EU), with associated phytosanitary measures in place to prevent its spread through the various
means of dispersal. One such means of dispersal is the water used for irrigation in nurseries, which
can contain fungal propagules. Three different treatments, namely, Desogerme, Intra Hydrocare and
sodium hypochlorite (NaClO), were tested for their efficacy in eliminating F. circinatum spores in
water at several concentrations. Those that showed 100% disinfection rates were selected for further
assays regarding seed germination and water quality impact. From these studies, Desogerme 1%
and Intra Hydrocare 4% were then selected for large-scale seed germination and plant certification
assays in nurseries, where they showed promising results in regard to the prevention of infections in
nurseries, and in this way, contribute to the efforts of mitigating this disease.
