Disease is damaging Florida citrus crops. And Mark Brush reports… researchers say the citrus growers need a new kind of disease resistant tree:

The disease is called Huanglongbing disease and that’s Chinese for “yellow shoot disease.” It’s spread by a little Asian insect.

Right now, about 4% of the citrus crop in Florida is hit by the disease , but researchers say it can wipe out whole orange groves if it’s not contained.
The National Research Council says long term – growers should plant genetically modified trees that resist the disease.
George Bruening is a plant pathologist at the University of California – Davis and he chaired the study for the National Research Council:

“And so if you had a genetically modified tree, Florida citrus and the people of Florida would be very much ahead, because there would be less use of insecticides, for example.”

Bruening says these types of genetically modified orange trees don’t exist yet. And it’ll take years to develop them and get government approval.

Sour Taste for Florida’s Citrus

  • A recent study showed climate change was resulting in stronger hurricanes, and some years, Florida, with all of its orange groves, has been devastated by those storms. (Photo courtesy of the USDA)

Florida’s orange producers have
escaped any devastating hurricanes so far
this season. But in recent years, the big
storms have been worse. They’ve contributed
to a 40% decline in orange crops
in the last five years. Julie Grant reports

Florida’s orange producers have
escaped any devastating hurricanes so far
this season. But in recent years, the big
storms have been worse. They’ve contributed
to a 40% decline in orange crops
in the last five years. Julie Grant reports
that has some companies looking elsewhere
for oranges:

Matthias Guentert is president of Symrise. The company
makes flavorings for beverages and processed foods.

When Symrise was deciding where to open its new citrus
headquarters – Guentert says they considered Florida – but
then chose to open in Brazil instead. One reason: Florida’s
increasingly unpredictable weather.

“Weather has been affecting people in Florida and in the
south of the US in the last years. And when it comes to
making a decision like this, it does play into it.”

A recent study showed climate change was resulting in
stronger hurricanes, and some years, Florida, with all of its
orange groves, has been devastated by those storms.
