Pruning to Rehabilitate HLB-Affected Sweet Orange Trees

Josh McGillCitrus

By Tripti Vashisth and Troy Gainey In the last 11 years, Florida orange production has declined more than 60 percent.

Planting new groves in the face of HLB has become a daunting task for Florida growers. At the recent Citrus Expo, University of Florida researcher Ute Albrecht offered suggestions for those taking on the challenge. “Among the important things to consider when planting new groves are the site preparation, the planting of the trees, weed management, irrigation and nutrition, and …

Evaluation of HLB Treatments

Josh McGillCitrus Greening

By Stephanie Slinski Evaluating how well bactericides, nutritional programs or other treatments work against HLB can be difficult. Symptoms are not uniform between trees in a grove, and tree health fluctuates throughout the season, which may give the appearance of an effect. Rigorous field trials are the best way to test new treatments, but not every treatment program can be …

HLB and ‘Tolerance’ as a Practical Matter in Choosing Rootstocks

Tacy CalliesRootstocks

By classic biological definition, a particular citrus rootstock-scion combination when infected with Candidatus Liberibacter asiaticus (CLas) would be considered tolerant if infected trees had no more than slight reductions in performance, sometimes accompanied by a reduced level of the pathogen. That definition implies that the …
