Bacterioses on seed and other propagative material of vegetables, field crops and ornamental plants

Abstract

Bacterioses are considered one of the most important diseases of vegetables field crops and ornamental plants. Bacteria mostly overwinter and spread by seed. During last few decades, the role of seed as the major source of primary inoculum was increased, due to unlimited possibility of transportation. In our country bacterioses cause the most important yield lost of vegetables, especially of pepper, bean, potato and brassicaceae. Use of pathogen-free seed and other propagative material is considered as basic control measure for bacterioses. In order to obtain proper health condition this plant material should be visually field inspected during vegetation and checked in special laboratories according to standardized bacteriological methods.

Bakterioze na pojedinim ratarskim, povrtarskim i ukrasnim biljkama, spadaju među ekonomski najštetnije bolesti, a osnovni način njihovog održavanja i širenja je seme. Poslednjih decenija, sa ogromnim mogućnostima saobraćaja uloga semena kao izvora primarnog inokuluma znatno se povećala. U našoj zemlji ekonomski najštetnije su bakterioze povrća, pre svega paprike pasulja, krompira i kupusnjača. Osnovna mera zaštite, u cilju suzbijanja bakterioza je korišćenje zdravog semena i sadnog materijala. Da bi se obezbedilo zdarvo seme i drugi reprodukcioni materijal, zdravstveno stanje semen-skih useva treba kontrolisati još tokom vegetacije, a pre bilo kakvog transporta, kontrolu treba izvršiti u specijalizovanim laboratorijama, prema standardizovanim bakteriološkim metodama.
