Albugo is a genus of fungi known for causing white rust diseases in various plants, particularly in the family Brassicaceae, which includes crops like cabbage and broccoli. These fungi are obligate parasites, meaning they can only grow on living host plants. They produce white, powdery spores that can be seen on infected leaves and stems. The life cycle of Albugo involves both asexual and sexual reproduction. Infected plants may show symptoms such as yellowing leaves, stunted growth, and the formation of galls. Effective management includes crop rotation and the use of resistant plant varieties to minimize the impact of these pathogens.
