Udk 633:632.93 Bacterial Diseases of Plants: Epidemiology, Diagnostics and Control

Of recognized more than 5000 bacterial species, over 100 are the causal agents of plant diseases. They constitute a very important factor limiting growth and cropping of cultivated plants. The pathogenic bacteria are divided into two major groups: eubacteria possessing cell wall and ability to grow on artificial media and bacteria without cell wall but surrounded by cell membrane only. To the last group called mollicutes, formerly known as mycoplasmalike organisms, phytoplasmas and spiroplasmas belong. The latest advances in research on plant bacterioses caused by eubacteria are presented.
