The use of highly HLB-tolerant genotypes as interstocks on a tree with a Swingle rootstock and a Valencia scion infected with HLB is offering hope for help against HLB, Jude Grosser reports. Grosser is a plant breeder with the University of Florida Institute of Food and Agricultural Sciences at the Citrus Research and Education Center in Lake Alfred. “Virtually every …
Column sponsored by the Citrus Research and Development Foundation The mission of the Citrus Research and Development Foundation (CRDF) is to advance disease and production research and product development activities to ensure the survival and competitiveness of Florida’s citrus industry through innovation. Since the inception of CRDF, the majority of investment has focused on HLB, while still addressing strategic topics …
Jim Snively, vice president of grove operations at Southern Gardens Citrus, discusses his company’s management of HLB and the psyllids that spread it.

New clues to how the bacteria associated with citrus greening infects the only insect that carries it could lead to a way to block the microbes’ spread from tree to tree, according to a study in Infection and Immunity by Agricultural Research Service (ARS) and Boyce Thompson Institute (BTI) scientists. Citrus greening, also known as huanglongbing (HLB), is a serious disease dramatically …
