Abstract: | The airborne dispersal of the anamorphs of the Gibberella fujikuroi species complex was studied under pre- and postharvest maize (corn) production conditions using a 3-stage Andersen sampler. The aim of this study was to identify and analyse the size distribution of such species in air samples. Differences were observed between the concentration of large- and small-sized propagules (identified as aggregates and single microconidia, respectively), but the difference was only significant during a high concentration period (October 2007, P = 0.009). No correlation was found between the concentration of fusaria found at different sampling heights (10 and 150 cm above ground level). Fusarium isolates were collected and identified based on morphological characters and using species-specific PCR assays. The PCR analysis confirmed morphological identification of F. verticillioides, F. proliferatum and F. subglutinans. High concentrations were found during the maize harvest, loading and corn shelling. Our results showed that the monitoring of F. verticillioides should be performed at a single sampling height. |
