Erysiphe Cruciferarum
''Erysiphe cruciferarum'' is a plant pathogen of the family Erysiphaceae, which causes the main powdery mildew of crucifers, including on ''Brassica'' crops, such as cauliflower, cabbage, broccoli, and Brussels sprouts. ''E. cruciferarum'' is distributed worldwide, and is of particular concentration in continental Europe and the Indian subcontinent. ''E. cruciferarum'' is an ascomycete fungus that has both sexual and asexual stages. It is also an obligate parasite that appears to have host specificity; for example, isolates from turnip will not infect Brussels sprout, and vice versa. While being a part of the family Erysiphaceae, it belongs to those members in which the conidia are formed singly and whose haustoria are multilobed. This species is also being evaluated as a potential biological control for the invasive plant garlic mustard. Signs and symptoms ''Erysiphe cruciferarum'' exhibits typical powdery mildew characteristics, appearing as small radiating, diffuse colonies ...

Plant Pathology
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungus, fungi, oomycetes, bacterium, bacteria, plant virus, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other Plant defense against herbivory, pests that affect plant health by eating Plant tissue, plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, wat ...
