In fact, most fungal, bacterial and viral plant diseases are spread naturally by wind currents, rain, soil seeds, insects and other animals. 3, edited by Horsfall and Dimond, was the birth of modern plant disease epidemiology. The efficient and economic control of a plant disease is dependent on crop value, effectiveness of control measure, risk involved and cost/benefit ratio. (Revised 2011). The basic strategy assumes that most pathogens can travel only short distances without the aid of some other agent such as humans or other vector, and that natural barriers like oceans, deserts, and mountains create obstacles to their natural spread. •Signs of plant disease are physical evidence of the … Plant diseases are caused by the vast circle of diversified pathogens which continuously tend to undergo mutations and recombination, thus generating their new strains efficiently for their survival in the ecosystem (Ventura et al., 2007; Cangi et al., 2016). Plant disease epidemiology is the study of disease in plant populations. Others can survive on nearby dead plants or infected gardening tools. Looks like you’ve clipped this slide to already. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants.

The interaction of lesion nematodes (mainly P. penetrans - Figure 8) and Verticillium wilt fungi (mainly V. dahliae) results in a disease complex known as "potato early dying syndrome" that has become of increasing economic significance within the last decade. This principle is defined as any measure that prevents the introduction of a disease-causing agent (pathogen) into a region, farm, or planting. There may be infectious disease and contagious disease. disease in a population. ADVERTISEMENTS: In this article we will discuss about the classification of plant diseases. An epidemic has been defined as any increase of disease in a plant population. Plant Disease is the leading international journal for rapid reporting of research on new, emerging, and established plant diseases. Autonomous or direct or active dispersal In this method the dispersal of plant pathogens takes place through soil, seed and planting material during normal agronomic operations.
