the current citrus disease situation in Florida and the status of public and private efforts to address citrus greening and other diseases; including lessons learned; 2) the capacity of the industry to mobilize a scientifically based response to current disease threats and to translate scientific advances into products and services for the protection of Florida citrus industry in the short and long term, and 3)

7. Increased use of insecticide sprays, as currently required for successful suppression of ACP populations, brings with it risks of ACP developing resistance to one or more of the most useful insecticides and of adverse affects on beneficial insects.

The Florida Citrus Industry The favorable conditions for citrus production in Florida have allowed the industry to grow to the point of having a $9.3 billion annual economic impact on the state. Throughout the Florida citrus industry's history, this success has been tempered and defined by the adverse effects of the natural calamities of freezes, hurricanes and diseases, and, in more recent times, by urbanization, international competition, and shortage of water.

Production of healthy citrus trees in "closed," insect-proof nurseries is established practice in Florida. The other two prongs of current HLB mitigation are reducing inoculum sources and suppressing ACP.

Citrus research has been funded by several national, regional, state, and citrus industry organizations. Following the detection of HLB in Florida, the Florida Citrus Production Research Advisory Council (FCPRAC)

More complete knowledge of economic impacts will allow fine-tuning of research priorities for the urgent task of keeping the citrus industry viable, while new approaches to longer term HLB mitigation are being advanced (Recommendations O-4 and In-3)

From page 8... ...
These and other research approaches that can enhance HLB management in the short-term are discussed in the Summary section on Essential Research Directions. Actions Needed for the Sustainable Management of Huanglongbing in the Future The consensus approach to the long-term management of HLB is to deploy citrus lines resistant to CLas and ACP, which can be accomplished in principle by: (i)

Thus, biological control alone is not likely to reduce ACP populations sufficiently to provide HLB mitigation. To date, significant reductions in psyllid populations have been achieved in Florida only through the application of insecticides.
|
From page 10... ...
Young trees require aggressive ACP suppression involving the soil-applied systemic insecticides aldicarb or imidacloprid. Other recommendations take into account the relatively low psyllid populations that occur during winter, when broad-spectrum foliar sprays may be applied to mature trees to suppress populations of overwintering adults.

From page 11... ...
The usual application for a transient expression vector such as CTV is as a test bed for evaluating gene constructions intended for later use as transgenes. However, the longevity of expression shown by CTV constructions could allow direct application of this technology to confer commercially useful resistance to CLas and to do so in significantly less time than would be required for creation and deployment of a resistance gene in genetically transformed citrus.
