Although Sharka is a well-known disease in the Upper Rhine region, the spread of new invasive recombinant strains of the Plum Pox virus (PPV) is unclear. These strains are more aggressive and have a higher potential for damage than the hitherto widespread PPV-D strains. RLP AgroScience is investigating the possible distribution of these strains in natural habitats like hedge rows (Plant Viruses).
RLP AgroScience investigates the overwintering parameters (population dynamics, activity, overwintering sites) as well as the cold tolerance of spotted wing drosophila. (D. Suzukii).
Flavescence dorée is a quarantine disease of grapevine. The vector, the American grapevine leafhopper Scaphoideus titanus, was detected in the context of InvaProtect 2016 for the first time in Alsace. RLP AgroScience is investigating whether alder near vineyards is naturally already infected with those phytoplasmas that, once transferred to wine and propagated there by S. titanus, can cause flavescence dorée. For this purpose, a risk map was created (Risk map PGY / FD).
