Detection and control measures

Various methods are possibly used to detect phytoplasmas: biological indexing (grafting on indicator plants), serology for certain strains, molecular PCR tests (universal phytoplasma primers or primers specific to the stolbur phytoplasma) or electron microscopy.

Stolbur is one of the quarantine pathogens listed by the European Union on the potato and is thus subject to mandatory control measures.

In regions where phytoplasmas are present, preventive measures include:

• destroying vector leafhoppers (insecticides) and weeds;
• avoiding the proximity of host plants;
• using only certified seed potatoes.
