Symptoms The underground rhizome is a light-brown, round lesion. The disease is rotted. The tissue is discrete and subsidence. The shape is round or oval. The diameter is 5 to l0mm. The lesions in severe cases are connected to large blocks, affecting the yield and quality of the odoratum. .
The pathogen Fusariμm solani (Mart.) Sacc.f.sp.radicicola (Wr.) Snyd. & Hans. said that the eggplant fungal spore root disease is a specialized type, belonging to the fungus Fungi. On the PSA medium, the flora was white to lavender, and the medium was purple on the reverse side, floccular, and luxuriant. A lot of small conidia, born on solitary vials, colorless unit cells, oval to spindle-shaped, size 6-152-4 (μm); large conidia produced in branching conidiophores On the spore cells of the spore type, the spores of the large conidiospores, colorless, slightly curved, slightly apical cells, podocytes more blunt, 3-5 diaphragm, generally 3 separated 20-352.6-4. 7 (μm), accounting for the vast majority; 5 separate 24-313.1-4.4 (μm), rarely.
The thick-walled spores produced many, single or 2-3 strings, spherical, pale yellow, 6-116-9 (μm). On rice medium, the aerial mycelium was lush, flocculent, light purple to purple or light rose to light purple, resulting in a large number of microspores, with very few megaspores, and there were more megaspores on the Dianthus caryophyllus medium. Does not produce behavior. The results of the pathogenicity test were consistent with that of Fusariμm solani f. sp. radicicola. See Fusarium graminearum.
