The most important bacterial diseases of crops in greenhouse

Abstract

Plant growth conditions in protected environments can be as favorable for plants even more favorable for their pathogens, contributing to higher severity of particular diseases. Bacterial diseases mostly occur in poorly maintained not-climatized objects, or in crops grown from uncertified seed. Apart from losses taking place in protected conditions, serious damage can occur due to bacteria distribution outdoors by contaminated transplants. High infectivity and limited control possibilities reduce solution choices for management of plant pathogenic bacteria in protected environments. Therefore, improvement of knowledge on all potential pathogens is essential for their control.

Uslovi gajenja biljaka u zaštićenom prostoru, koliko odgovaraju biljkama, često još više odgovaraju njihovim patogenima i doprinose jačoj pojavi nekih oboljenja. Pojava bakterioza uglavnom se uočava u objektima sa lošim higijensko-tehničkim merama, bez mogućnosti regulacije mikroklime ili prati usev poreklom iz nedeklarisanog semenskog materijala. Osim štete koja nastaje za vreme proizvodnje u zaštićenom prostoru, bakterioze se rasadom mogu proširiti na veće površine na otvorenom polju i tako uvećati gubitke u proizvodnji. Usled velike infektivnosti i ograničenih mogućnosti suzbijanja, kontrola fitopatogenih bakterija na usevima u zaštićenom prostoru predstavlja teško rešiv problem. Stoga je poznavanje svakog patogena ponaosob od presudnog značaja za izbor mera njegovog suzbijanja.
