Why Bicarbonates Matter for HLB Management

Josh McGillNutrition

By Jim Graham and Kelly Morgan Huanglongbing (HLB), greening and yellow shoot are names for the most devastating citrus disease in the world. Symptoms of HLB include a distinctive chlorotic mottle on fully expanded leaves. Infected shoots are stunted, and branches gradually die back as the symptoms appear in other sectors of the tree canopy. HLB reduces fruit size, weight …

How Much Psyllid Control Needed for HLB?

Ernie NeffCitrus

Soon after Florida’s citrus industry realized it couldn’t eradicate HLB, researchers and growers put a huge emphasis on controlling the Asian citrus psyllids that spread the disease. Most still agree that psyllid control remains essential in the short term to survive HLB. But many are now questioning the long-term economic sustainability of massive levels of psyllid control. Such questioning took …
