Abstract

The invention discloses a crocus sativus endophytic fungus and an application thereof in control of corm rot, and belongs to the technical field of plant disease prevention and control. The endophytic fungus is separated from crocus sativus living bodies of plants ofcrocus sativus, iridaceae by adopting an endophytic fungi separation and purification technology, belongs to trametes fungi, polyporales, polyporaceae, and is classified and named as trametes versicolor CS05. The preservation number is CGMCC (China General Microbiological Culture Collection Center) No. 21948. The invention also discloses an application of the endophytic fungus: the endophytic fungus can inhibit the hypha growth of the corm rot pathogenic bacteria Fusarium oxysporum of the crocus sativus, the relative inhibition rate is 76.53%, meanwhile, the condition of the corm rot of the crocus sativus is effectively relieved, and the condition index is reduced by 81.13%. The endophytic fungus provided by the invention has an obvious effect of controlling the corm rot of the crocus sativus, and brings a wide application prospect to the field of biological control of crocus sativus fungus diseases.
