Pectobacterium spp. are necrotrophic bacterial plant pathogens of the family Pectobacteriaceae, responsible for a wide spectrum of diseases of important crops and ornamental plants including soft rot, blackleg, and stem wilt. P. carotovorum is a genetically heterogeneous species consisting of three valid subspecies, P. carotovorum subsp. brasiliense (Pcb), P. carotovorum subsp. carotovorum (Pcc), and P. carotovorum subsp. odoriferum (Pco).

Fusarium wilt is a soil-borne disease, which negatively affects the lentil crop widespread in India and affecting the lentil crop productivity. So the present study was conducted to evaluate the efficacy of bioagents against wilt pathogen Fusarium oxysporum f.sp.lentis of lentil crop through antagonistic activity. Rhizospheric strains were isolated from wilt affected lentil plant in different regions of Eastern UP like Faizabad, Mau, Varanasi, Ghazipur. A total of 20 bacterial strains were isolated and tested for antagonistic activity by co-culture m

Seed-borne diseases are a major problem in Kenya since many farmers have no access to certified seeds. The objective of the study was to study the influence of potato seed production systems on potato seed borne diseases. A survey was carried out in five major potato growing counties in various agro-ecological zones (AEZs).

There exists a lot of controversy regarding the prevalence of strains in the various parts of the world. In India, however, scant information is available about the prevalence of biovars/races and strains in various parts of the country. Understanding local pathogen genetic diversity is the first step in a successful breeding and integrated disease management programme. One of the purposes of the present investigation on six isolates of R.
