    Leaf spots are a type of plant disease that are usually caused by pathogens and sometimes other cases such as herbicide injuries. [3] Leaf spots can vary in size, shape, and color depending on the age and type of the cause or pathogen.

  6. 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 ...

  7. Plant virus - Wikipedia

    en.wikipedia.org/wiki/Plant_virus

    Plant viruses can be pathogenic to vascular plants ("higher plants"). Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope. The great majority have an RNA genome, which is usually small and single stranded (ss), but some ...

  8. Pathogen - Wikipedia

    en.wikipedia.org/wiki/Pathogen

    Bacterial plant pathogens cause leaf spots, blight, and rot in many plant species. [38] The most common bacterial pathogens for plants are Pseudomonas syringae and Ralstonia solanacearum, which cause leaf browning and other issues in potatoes, tomatoes, and bananas. [38] Brown rot fungal disease on an apple.
