FUSARIOSIS DISEASE SPREAD AND PATHOLOGY DEVELOPMENT INDEX IN ALFALFA

The presented is devoted to the study of ecological and biological characteristics of Fusarium species that infect different varietes of alfalfa from cultivated fodder plants and the fusariosis pathologies caused by them. It was determined that 7 species of Fusarium genus : F.avenaceum (Fr) Sacc., F.gibbosum APP. et Wr., emend Bilai, F.solani (Mart) App.et.Wr., F.oxysporium Schlecht. Emend Snvd. Et Hans., F.sambucinum App.et Wr, F.bullatum Sherb., F.redolens Bilai are found in the cultivated alfalfa plant. At the same time, it became known that if the Fusariosis disease recorded in alfalfa is caused by not one, but several species of fusariosis fungi, then the course of the pathology becomes more acute. Also, it was clarified that fusariosis disease is observed in all stages of the alfalfa plant vegetation period
