该项目的目的是在2005年至2014年期间提供关于芬兰谷物中发现的镰刀菌物种及其产生的毒素的最新信息，因为芬兰对镰刀菌物种及其毒素的最后一次全面调查研究是在1960年代和1970年代之交进行的。另一个目的是使用最新的分子和化学方法来调查芬兰镰刀菌物种及其真菌毒素的发生和相关性。FinMyco项目2005年和2006年在芬兰发现的最常见的镰刀菌物种是F. avenaceum、燕麦F. culmorum，F.禾谷镰孢F. poae，F. sporotrichioides和F.兰塞西亚。F.燕麦是大麦、春小麦和燕麦样品中的优势种。F. culmorum和F.燕麦和大麦中的禾谷氨酰胺含量较高。冬季谷物中镰刀菌感染率最低。2005年镰刀菌的发病率比2006年高得多，原因是天气条件。F.自2001年以来，兰瑟西在芬兰变得更加普遍。F.禾谷胶的重要性也在上升。在芬兰燕麦、大麦和小麦中发现禾谷镰刀菌DNA和脱氧雪腐镰刀菌烯醇（DON）水平之间存在高度显著的相关性。在将FinMyco 2005-06年的数据与芬兰2005-14年安全监测方案的结果进行比较时，注意到春季谷物更容易受到镰刀菌真菌的感染和毒素的形成。2005- 2014年期间，芬兰的T-2和HT-2毒素含量以及异常高浓度DON的频率都有所增加。在2005-06年，白僵菌素（Bauvericin）、恩氏杀菌素（恩斯）和念珠藻素（MON）也是芬兰谷物中非常常见的污染物。气候变化导致天气变暖，这可能表明芬兰镰刀菌菌群和毒素含量和概况在不久的将来会发生更多变化。
The aim of the project was to produce updated information during 2005-14 on the Fusarium species found in Finnish cereal grains, and the toxins produced by them, as the last comprehensive survey study of Fusarium species and their toxins in Finland was carried out at the turn of the 1960s and the 1970s. Another aim was to use the latest molecular and chemical methods to investigate the occurrence and correlation of Fusarium species and their mycotoxins in Finland. The most common Fusarium species found in Finland in the FinMyco project 2005 and 2006 were F. avenaceum, F. culmorum, F. graminearum, F. poae, F. sporotrichioides and F. langsethiae. F. avenaceum was the most dominant species in barley, spring wheat and oat samples. The occurrence of F. culmorum and F. graminearum was high in oats and barley. Infection by Fusarium fungi was the lowest in winter cereal grains. The incidence of Fusarium species in 2005 was much higher than in 2006 due to weather conditions. F. langsethiae has become much more common in Finland since 2001. F. graminearum has also risen in the order of importance. A highly significant correlation was found between Fusarium graminearum DNA and deoxynivalenol (DON) levels in Finnish oats, barley and wheat. When comparing the FinMyco data in 2005-06 with the results of the Finnish safety monitoring programme for 2005-14, spring cereals were noted as being more susceptible to infection by Fusarium fungi and the formation of toxins. The contents of T-2 and HT-2 toxins and the frequency of exceptionally high DON concentrations all increased in Finland during 2005-14. Beauvericin (BEA), enniatins (ENNs) and moniliformin (MON) were also very common contaminants of Finnish grains in 2005-06. Climate change is leading to warmer weather, and this may indicate more changes in Finnish Fusarium mycobiota and toxin contents and profiles in the near future.
