Necrotrophic Pathogens

Necrotrophic pathogens are pathogenic organisms that cause disease in plants by obtaining nutrients from dead or decaying cells. These pathogens exploit their host’s metabolic weakness, leading to tissue destruction and death. Necrotrophic pathogens are responsible for causing numerous crop diseases and are among the most damaging and economically significant threats to crop production worldwide. They produce toxins, enzymes and other chemicals that break down cell walls, allowing the organisms to enter and feed on the plant's tissue. Management of necrotrophic plant diseases requires an understanding of the organisms and their life cycles, as well as proper identification of the affected plants and proper control and management of the affected areas. Effective management strategies may involve cultural, chemical, or biological control measures.
