Abstract

The development of any disease or disorder is termed pathogenesis. With respect to plants, any pathogen whether it is fungi, bacteria, or viruses which interfere with normal functioning of the plants is termed plant pathogenesis. After the onset of infection, the plant’s normal structure and metabolic functions are disturbed, hence, leading to unbalanced physiological process. There are various factors which contribute in the disease progression like soil pH, relative humidity, temperature, soil fertility, and moisture. The susceptibility and disease proneness of the plant host, multiplication rate of the infectious entity, and the adequate inoculum potential along with a biotic component mediate the successful infection process in the host plants. Plant’s pathogenic microorganisms affect its growth and thereby reduce the agricultural productivity. The proper understanding of pathogenicity and basis for plant disease control is essential. The first step involved in controlling the disease is to identify the mechanism of disease outbreak, next is to derive new control measures by natural phenomenon which is inbuilt within the plant parasite interaction.
