在非黑钙土地带,由镰刀菌(Fusarium)引起的苜蓿根腐病传播的很快,导致苜蓿幼苗和根大量死亡。因此,使其草地草层稀疏,而降低了饲料的产量。从有病植株中可分离出真菌、细菌和病毒。关于苜蓿死亡的原因,目前学者们的意见还不一致。(1982)根据大量的研究结果表明,在苜蓿大田经常引起作物发病的病原菌,不是细菌和病毒,而是真菌——尖镰孢霉(Fusarium oxysoporum)。

In non-Chernozem soil, the root rot of alfalfa caused by Fusarium spread rapidly, resulting in a large number of deaths of alfalfa seedlings and roots. As a result, sparse grass and grass, and reduced feed production. Fungi, bacteria and viruses can be isolated from diseased plants. The reasons for the death of alfalfa, the views of scholars are not the same. (1982) based on a large body of research showing that the pathogen that frequently causes crop disease in alfalfa fields is not bacteria and viruses but the fungus Fusarium oxysoporum.
