Citrus greening disease or HLB has severely impacted Florida citrus production. And while many solutions have been proposed, there is interest in a number of trees that have shown to not show symptoms of the disease. This week's episode discusses the disease with retired extension specialist Gary England as he evaluates "survivor" trees. These trees continue to produce even when infected, and may provide insights into resistance to the disease, as well as provide genetics to maintain the Florida orange juice industry until other options are available.
