Urgency, cooperation, and persistent management are needed among producers, processors, government officials, and scientists while solutions are developed and implemented to combat the citrus greening disease threatening Florida citrus production, says a new report from the National Research Council. Requested by the Florida Department of Citrus, the report lays out a strategic plan to control citrus greening and develop a comprehensive solution to diseases that damage citrus crops.
After infection, the first symptoms may appear in six to 18 months, with relatively fast progression of the disease throughout an orchard. As the severity of the disease increases, citrus yield drops and could make the orchard?EUR??,,????'?????<???EUR?s production uneconomical in seven to 10 years after planting. The committee that wrote the report found that citrus greening and measures taken to control it reduced Florida orange juice production by several percent by 2008, and losses will likely increase. However, if the disease advances rapidly and more than a few percent of the trees in a grove must be removed every year, production will not be sustainable in today?EUR??,,????'?????<???EUR?s citrus industry, the committee concluded.
The most powerful long-term management tool likely will be the cultivation of citrus trees resistant to the bacteria that cause citrus greening and to the Asian citrus psyllid, the committee said. Genetic engineering holds the greatest hope for generating trees with these traits.
