About the Book
"Crop losses by diseases and are as old as plant themselves but as agriculture are strengthened and cropping techniques including the cultivation of high yielding varieties and hybrids are varying over time the impact of the pests becoming gradually important. Frequent fungal, bacterial and nematode species as well as viruses are considered serious pests in agriculture. Losses in crop yields due to disease need to be reduced in order to meet increasing global food demands associated with growth in the human population. There is a well-recognized need to develop new environmentally friendly control strategies to combat bacterial crop disease. The current handbook is going to put plant protection approaches from bacterial diseases in perspective. Bacteria as plant pathogens can cause severe economically damaging diseases, ranging from spots, mosaic patterns or pustules on leaves and fruits, or smelly tuber rots to plant death. They do great harm to many agricultural crops, especially cotton, tobacco, tomatoes, potatoes, cabbage, and cucumbers. The diseases may be systemic causing the death of the entire plant or individual parts thereof; they may appear on the roots or in the vascular system. Plant pathogenic bacteria are heterotrophic organisms, which can develop on host plants as parasites. They are not able to penetrate directly plant tissue. Infection usually occurs through natural openings like stomata, hydatodes, nectaroides as well as injures of various origin. The important places of infection appeared to be leaf scars. Most of plant pathogenic bacteria can survive on plant surfaces also as epiphytes and some as saprotrophes. However, many bacteria infecting above ground organs are not able to survive on dead plant debris. When the infected tissue dies, the number of bacteria rapidly decreases, which leads to their total decline. In such situations, infection source can be drastically reduced, which is very important from practical point of view. The bacteria infecting above ground part of plants are disseminated by wind, rain, insects, and birds as well as infected plants. Pathogens of root system are spread mainly by soil solution and soil fauna. Important role is played by man, also through management practices. Some bacteria can be disseminated with nursery material, like seeds, scions and seedlings.
Two-Volume ‘Brig’s Handbook of Methods & Research in Identification of Bacterial Diseases of Plants’ examines the progress and challenges for phage-based disease biocontrol in food crops; describes bacterial plant-pathogen interactions and control measures involving the use of traditional chemicals or antibiotics losing their efficacy due to the natural development of bacterial resistance to these agents. In addition, there is an increasing awareness that their use is environmentally unfriendly. Bacteriophages, the viruses of bacteria, have received increased research interest in recent years as a realistic environmentally friendly means of controlling bacterial diseases. Their use presents a viable control measure for a number of destructive bacterial crop diseases, with some phage-based products already becoming available on the market. Phage biocontrol possesses advantages over chemical controls in that tailor-made phage cocktails can be adapted to target specific disease-causing bacteria."
