FEATURES OF THE SPREAD OF PHYTOPATOGENIC FUNGI IN THE VEGETATIVE AND GENERATIVE ORGANS OF FODDER PLANTS (IN THE EXAMPLE OF ALFALFA PLANT)

Abstract The presented work is devoted to the study of the propagation characteristics of phytopathogenic fungi in both underground and aboveground vegetative and generative organs of cultivated fodder plants, including different varieties of alfalfa. It has been determined that, Ascochyta viciae Lib., A.imperfacta Peck., A.trifolii Bond., Sclerotinia libertiana Fuck., Ustilago Zeae Beck fungi can spread equally in all organs of the alfalfa plant, that is, in both generative and generative organs. They are also called “universal fungi”. At the same time, it was known that Microsporum commune Rabh., Fusarium oxysporium Schl and F. bulbigenum Cke et Mass fungi infect only the leaf, Rhizopus nodosus Namysi only the flower, and Pythium de baryanum Hess, Fusarium sporotrichiella Sacc only the root. These are called “specific fungi”. Also, comparison of vegetative and generative organs of alfalfa plant shows that leaves are most infected with diseases.References: 1.
