[Phytopathogenic bacteria of couch-grass in the crops of wheat].
Bacterialdiseases of weeds in the crops of wheat on the fields of Kyiv and Vinnytsya regions of Ukraine Elytrigia repens (L.) Nevski Agropyrum repens L. were revealed. The following symptoms of bacterial affections: the leaves wither, oval or hatched necrotic spots on green leaves, necroses on the stalks, empty-ears, partial blackening of the ear axes, awns, caryopsises, scales, water-soaked or dark brown with violet shade spots on the rhizomes were found. During the vegetation period bacteria were isolated from the affected plants which caused pathological process in the couch-grass and wheat. The pathogenic bacteria were identified as Pseudomonas syringae, P. viridiflava, Pseudomonas sp., Erwinia carotovora pv. carotovora, Pantoea agglomerans, the part of yellow-pigmentary isolates were not identified.
