One of the most important pathogens producing diseases in carrots, Candidatus liberibacter solanacearum (CaLsol) occurs yearly in carrot-production areas in Spain (including areas of the Canary Islands). Fields show symptoms of curling, yellow, bronze, and purple discoloration of leaves, stunting of shoots and tap roots, and prolferation of secondary roots. It reduces the carrot yield considerably and it is key for the producers to reduce the impact of this disease. For this, several studies are carried out by government institutions, local producers cooperatives and private companies to develop an efficient control method of the vector of CaLsol, the psyllid Bactericera trigonica.
SynTech Research Spain is involved in the efficacy studies for the control of such a relevant vector. The program consists in field and lab work assessing the vector populations in its different stages, evaluating disease symptoms and crop yield.
Once more transmission of plant diseases by insects is a challenging topic to deal with.
