Potatoes are susceptible to numerous diseases – mainly, viruses and bacteria transmitted from one year to the next via the plant (seed tubers). In order to guarantee the continuity of this crop, Agroscope cooperates with the seed sector to certify seed potatoes and develops strategies for controlling diseases which adversely affect their quality. Certification and the control of quarantine diseases of the plants are legal tasks defined by ordinances controlling the quality requirements for plants that are authorised for sale. Agroscope trials aim to control two diseases affecting seed-potato crops in particular – the Y virus (PVY) and pectinolytic bacteria (Pectobacterium and Dickeya).
