  2. Plant virus - Wikipedia

    en.wikipedia.org/wiki/Plant_virus

    Although plant viruses are not as well understood as their animal counterparts, one plant virus has become very recognizable: tobacco mosaic virus (TMV), the first virus to be discovered. This and other viruses cause an estimated US$60 billion loss in crop yields worldwide each year. Plant viruses are grouped into 73 genera and 49 families ...

  3. Plant disease - Wikipedia

    en.wikipedia.org/wiki/Plant_disease

    Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]

  4. Plant pathology - Wikipedia

    Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease.

  5. Pathogen - Wikipedia

    en.wikipedia.org/wiki/Pathogen

    Notable plant viruses include the papaya ringspot virus, which has caused millions of dollars of damage to farmers in Hawaii and Southeast Asia, [36] and the tobacco mosaic virus which caused scientist Martinus Beijerinck to coin the term "virus" in 1898. [37] Bacterial plant pathogens cause leaf spots, blight, and rot in many plant species. [38]

    A leaf spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis (cell death). [1]

  7. Plant disease epidemiology - Wikipedia

    en.wikipedia.org/wiki/Plant_disease_epidemiology

    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. [1] Plant disease epidemiologists strive for an understanding of the cause and effects of disease and develop strategies to intervene in situations where crop ...

  8. Injury in plants - Wikipedia

    en.wikipedia.org/wiki/Injury_in_plants

    Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
