Plant pathology as a career

The main work of plant pathologist is to keep plants free from diseases. according to the American pathologist society the demand for plant pathologist is highly demanded. plant pathologist is the branch of farming in which information regarding various diseases due to bacteria and viruses and their methods of treatment is given.this is the branch directly related to micro plaza fungi bacteriology etc. Plant Pathology is the study of plants and their pathogens,Plant diseases are caused by a variety of living organisms (called pathogens) such as fungi, bacteria, viruses, nematodes. in country various there are various department an other agricultural institutes.you can also choose the plant pathology as subject in B.S.C you can also go for m.sc and P.hd. The study of disease in plants; it is an integration of many biological disciplines and bridges the basic and applied sciences. As a science, plant pathology encompasses the theory and general concepts of the nature and cause of disease, and yet it also involves disease control strategies, with the ultimate goal being reduction of damage to the quantity and quality of food and fiber essential for human existence. Control of plant disease is defined as the maintenance of disease severity below a certain threshold, which is determined by economic losses. Diseases may be high in incidence but low in severity, or low in incidence but high in severity, and are kept in check by preventing the development of epidemics. The principles of plant disease control form the basis for prevanting epidemics. However, the practicing agriculturist uses three approaches to the control of plant disease: cultural practices affecting the environmental requirement of the suscept-pathogen-environment triangle necessary for disease development, disease resistance, and chemical pesticides. There are various diseases caused in past: * The Irish potato famine in the 1800 s killed 1.5 million people, one fourth of Ireland s total population. The crop was lost to late blight of potato, a fungal disease. * In the mid 19th century downy mildew grape disease was accidentally introduced in Europe. Downy mildiew of grape almost destroyed the vineyards in France, Germany and Italy. * Ergot of rye grain causes hallucinations and sometimes deadly illness. Massive European epidemics caused by ergot of rye occurred frequently during medieval times. * In the early 20th century the American Chestnut tree was wiped out by an Asian blight disease. The chestnut was a major source of lumbur at the time. some other types of diseases are: powdery mildew black rust of diseases downy mildew etc.
