Bakai,V.P.
In a course of the route surveys of potato crops there was studied the occurrence of potato bacterial black leg and soft rot. The research was realized in the Republic of Belarus in 1999-2002 in the department of the Scientific and Practical Center of the National Academy of Sciences of Belarus for Potato, Vegetable and Fruit Growing, Samokhvalovichi (Belarus). As a result of realized research there was revealed the dependence of potato affection by diseases on weather conditions. The strain composition of the causative agents of Pectobacterium carotovorum subsp. carotovorum and Pectobacterium carotovorum subsp. atrosepticum, their biology and correlation in dependence of the region of cultivation and a potato variety was studied. It was established that the ratio of the subspecies of black leg causative agents differed both by regions and varieties. Certain heterogeneity of the strain composition by biological and morphological properties was observed.
