HLB Reduction Strategies

Abstract

Management of huanglongbing (HLB) has focused on reducing the vector Asian citrus psyllid (ACP) and improving tree health, thus requiring a multi-pronged approach. Several elements of an HLB management system are either available or under current investigation. Maintenance of clean nursery stock, vector management and tree nutrition are widely implemented, while incorporation of tolerant or resistant varieties and pathogen reduction with bactericides are tactics that continue to be developed. Once in the field, trees are subject to psyllid attack and HLB infection. Strategies to reduce the incidence of this vector-pathogen complex are discussed below.
