This disease can be distinguished from Clavibacter by the bacterial slime produced from wounds, which is not seen in Clavibacter [...] found soil-inhabitant in tropical and subtropical regions and is transferred by the introduction of propagation materials (seed potatoes, cuttings of ornamentals [...] infected plants to neighbouring plants. The bacteria can also be transported by irrigation water. Disease incidence is highest when soil moisture is high

Eggs are deposited in leaf tissue in a slit cut by female. Eggs are colourless to pale white in colour. The nymphs resemble the
