Description
Summary:After the first record of CaLsol on symptomatic carrots and celery from two fields in Austria in 2014, monitoring activities on plants and potential vectors were undertaken on 20 fields in the outbreak area around the villages of Arzl, Rum and Thaur (Inn valley near Innsbruck, Tyrol) between 2016 to 2019. Of these species, CaLsol symptoms were only observed in carrot (leaf reddening and deformed roots with increased adventitious roots) and celery (leaf yellowing of the leaves and stunted petioles; Fig. 1). Psyllids were collected from carrot fields in the Inn valley and samples were obtained by agitating the crop canopy and collecting samples using a net held underneath.
