We evaluated Fusarium verticillioides and fumonisin contamination in maize samples after application of a non-aflatoxigenic Aspergillus flavus strain in the field. The sampling was performed 150 days after planting. The results showed a reduction in F. verticillioides frequency, as well as in fumonisin levels when samples were obtained from field areas treated with non-aflatoxigenic A. flavus strain. These results suggested a competition for substrate or space between fungi reducing the frequency of F. verticillioides and, consequently, fumonisin production.
我们评估了田间应用非产黄曲霉的黄曲霉菌株后玉米样品中镰刀菌和伏马菌素的污染情况。采样是在种植后 150 天进行的。结果表明，从用非产黄曲霉的黄曲霉菌株处理的田间区域获得的样品中，镰刀菌的频率以及伏马菌素水平均降低。这些结果表明，真菌之间对基质或空间的竞争减少了镰刀菌的频率，从而降低了伏马菌素的产生。
