Potato blight on leaf

Potato blight on leaf. Coloured scanning electron micrograph (SEM) of the potato blight fungus Phytophthora infestans, emerging from a potato leaf. Here, sporangiophores (dark green) are seen growing from the lip-like stomata on the underside of the leaf. Sporangiophores are hyphae, or filaments, which carry sporangia (spore sacs, brown). Leaf hairs, or trichomes, are the large green/yellow structures. The first widespread infection of commercial importance was in 1845, when most of Europe suffered decimated potato crops due to blight. Prevention of blight depends on spraying with fungicide and selective breeding. Magnification: x140 at 5x7cm size. x550 at 4.5x10ins

Decay Food Spoilage Fungus Potato Rotted Rotten Spoiled Sporangia Sporangium Stoma Worst Invasive Alien Species Blight Potato Blight

EDITORS COMMENTS
This print captures the devastating effects of potato blight on a leaf. The image, taken using a coloured scanning electron microscope (SEM), reveals the intricate details of the potato blight fungus Phytophthora infestans emerging from a decaying potato leaf. Dark green sporangiophores can be seen growing from the lip-like stomata on the underside of the leaf, while brown sporangia, or spore sacs, are carried by these filamentous structures. The large green and yellow structures in the image are leaf hairs, known as trichomes. This SEM magnification provides an up-close look at this destructive fungal disease that has had significant historical impacts. In 1845, Europe experienced its first widespread infection of commercial importance, resulting in decimated potato crops due to blight. Prevention and control measures for potato blight rely on spraying with fungicide and selective breeding techniques. This image serves as a reminder of how crucial it is to combat this invasive alien species that causes food spoilage and rotting. With a magnification level of x140 at 5x7cm size or x550 at 4.5x10ins size, this photograph showcases both scientific precision and artistic beauty. Captured by Science Photo Library, this print offers viewers an opportunity to appreciate nature's complexity even within microscopic realms while highlighting the ongoing battle against plant diseases like potato blight.
