Candidatus Liberibacter solanacearum is a bacterium that primarily affects plants, particularly those in the Solanaceae family, which includes crops like potatoes and tomatoes. It is transmitted by certain insect vectors, such as psyllids, and can lead to significant agricultural losses due to its impact on plant health. This bacterium is associated with diseases like zebra chip disease in potatoes, causing symptoms such as yellowing leaves and stunted growth. Management of Candidatus Liberibacter solanacearum involves controlling its insect vectors and implementing good agricultural practices to minimize its spread and impact on crops.
