To assess production of the mycotoxin moniliformin, inoculation trials with four barley cultivars and local isolates of Fusarium avenaceum were performed at two different experimental farms in southern Manitoba, Canada, during 1997-99. In the 1997 study, moniliformin was detected in 11 of 16 barley rows at levels between 0.19 and 1.62 mg g(-1), and F. avenaceum infection ranged from 10 to 57% in rows where the toxin was detected. In the 1998 study, moniliformin was detected in only three of 16 barley rows, with levels between 0.06 and 0.43 micro g g(-1), and F. avenaceum infection between 16 and 39%. In the 1999 study, moniliformin was detected in 11 of 16 barley rows with levels between 0.09 and 0.42 micro g g(-1), and F. avenaceum infection between 37 and 76%. In the 1997 trial, moniliformin was found in a single water-inoculated control row at 0.15 micro g g(-1). The data suggest that in years of high rainfall and F. avenaceum infection, moniliformin is likely to be found in Manitoba barley.
为评估霉菌毒素串珠镰刀菌素的产生情况，1997年至1999年期间，在加拿大曼尼托巴省南部的两个不同实验农场，用四个大麦品种和燕麦镰刀菌的本地分离株进行了接种试验。在1997年的研究中，在16行大麦中的11行检测到串珠镰刀菌素，含量在0.19至1.62毫克/克之间，在检测到毒素的行中，燕麦镰刀菌感染率在10%至57%之间。在1998年的研究中，16行大麦中只有3行检测到串珠镰刀菌素，含量在0.06至0.43微克/克之间，燕麦镰刀菌感染率在16%至39%之间。在1999年的研究中，16行大麦中的11行检测到串珠镰刀菌素，含量在0.09至0.42微克/克之间，燕麦镰刀菌感染率在37%至76%之间。在1997年的试验中，在一行水接种对照中发现串珠镰刀菌素，含量为0.15微克/克。数据表明，在降雨量大且燕麦镰刀菌感染的年份，曼尼托巴省的大麦中可能会发现串珠镰刀菌素。
