Florida fought to eradicate citrus canker for almost 100 years before giving up in 2006 after the historic hurricane seasons of 2004 (by the way I lived through it). Texas had eradicated the disease nearly 70 years ago, but now faces another battle of keeping this disease quarantined.
Let's hope that Texas can learn valuable lessons from Florida, about what works and what doesn't work. Florida spent ~$1 billion and removed 16.5 million citrus trees over ten years trying to eradicate the disease, but later gave up on their eradication efforts. Quarantine and eradication is the best first step, but spending time and money on research to develop disease resistance and other control strategies is also a wise choice. Extension education programs are important to raise awareness and understanding of Citrus Canker and other exotic diseases.
