Powdery mildew on leaf

Powdery mildew. Coloured scanning electron micrograph (SEM) of the parasitic powdery mildew Erysiphe sp. on a leaf. Hyphae (dark green) are the tangled filaments growing across the leaf surface which form the fungal colony. Rising up from the hyphae are asexual spores called conidiophores (green & brown). Powdery mildew is so-called because of the numerous white spores it produces. It is an agricultural pest which parasitizes leaves of certain grass, cereal and vegetable plants. Magnification: x230 at 5x7cm size. x600 at 5x7ins print

EDITORS COMMENTS
This print showcases the intricate world of powdery mildew, a parasitic fungus that plagues agricultural crops. The image, captured using a coloured scanning electron microscope (SEM), reveals the fascinating structure and life cycle of this plant pathogen. The leaf surface is adorned with tangled filaments known as hyphae, which form the foundation of the fungal colony. Rising from these hyphae are conidiophores, asexual spores that appear in shades of green and brown. These spores give powdery mildew its name due to their abundance and white appearance. Powdery mildew poses a significant threat to certain grasses, cereals, and vegetable plants commonly found in agriculture. As an agricultural pest, it thrives by parasitizing leaves and impeding plant growth and productivity. At a magnification level of x230 for a 5x7cm size print or x600 for a 5x7ins print, this photograph allows us to delve into the microscopic realm where pathogens like powdery mildew reside. Its striking visual details offer valuable insights into the biology and pathology behind this notorious plant parasite. This stunning image is part of Science Photo Library's collection on nature, disease, botany, agriculture, pathology, and more. It serves as both an educational tool for understanding plant diseases and an artistic representation of the hidden beauty within our natural world.
