Abstract
It was established, that the main cause of bacterial tomato wilting in the fields and greenhouses is Clavibacter michiganensis subsp. michiganensis, the agent of tomato bacterial canker. It is especially dangerous in the greenhouse soil, where it causes the mass plant diseases in the fruiting period. In greenhouses, the TBC appears as the vein disease, while in fields--as leaf and fruit disease. In conditions of artificial infection in fields, the ability of Cmm to cause the fruit rotting was found out. The isolates do not differ from those described in the literature by their phenotypical characteristics, by fatty acid content in particular. The sensitivity of isolates to pesticides, recommended for control of other tomato pathogens, was established. Antagonists, isolated from tomato seeds, are promising for the control.
