Thus, there is a need for new solutions to plant disease problems that provide effective control while minimizing negative consequences for human health and the environment [4, 10]. Biological control, using microorganisms to suppress plant disease, offers   What is Plant Disease? 0 Any disturbance that interferes with normal growth, development, function, economic value, or aesthetic quality of a plant. (slightly modified from Schumann) 0 Plant Disease can be caused by two general groups of causal agents 0 Biotic (pathogens) 0 Abiotic

  Biological control is the control of disease by the application of biological agents to a host animal or plant that prevents the development of disease by a pathogen. With regard to plant diseases the biocontrol agents are usually bacterial or fungal strains isolated from the endosphere or rhizosphere. Viruses can also be used as biocontrol agents and there is a resurgent interest in the use Plant Disease Control. It is very important to remember that a correct diagnosis is the most important step in the eventual control of a plant disease. Most diseases have a fairly well established control protocol. Most often, failure to control the disease happens because the

  Plant disease "control" in this sense is not practical, and in most cases is not even possible. Indeed, we need not eliminate a disease; we merely need to reduce its progress and keep disease development below an acceptable level. Instead of plant disease control, we need to think in terms of plant disease ://   the risk of disease. Many pathogens survive in crop residue, which can be a source of inoculum. • Varieties vary in their susceptibility to diseases. • Disease presence early in the season may result in greater yield loss than diseases that occur later in the season. • Fungicides do not affect diseases caused by bacteria, viruses, or Managing Plant

A plant disease can also be defined as any problem with the plant that leads to a reduction in yield or appearance.
