In agriculture, disease management is the practice of minimizing disease in crops to increase quantity or quality of harvest yield.
Organisms that cause infectious disease in crops include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Crops can also suffer from ectoparasites including insects, mites, snails, slugs, and vertebrate animals, but these are not considered diseases.
