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. Epidemiology is concerned simultaneously with populations of pathogens and host plants as they 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. 1946: Gäumann wrote the first book on plant disease epidemiology. Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. 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.

There may be infectious disease and contagious disease. 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).
