Regarding the 800 number we are hiring additional people to handle the calls. Without debating, the bottom line is that the disease will continue to move rather there is a moratorium or not. Every circumstance can not be explained, but there is a scale that is used that is described as more resistant to less resistant. The most resistant are mandarin oranges. The least resistant is grapefruit and key lime.
Oranges fall somewhere in the middle.
There is no evidence the disease is spread by birds and animals. Copper spraying was used until 1989 in Brazil as a control agent. If you take two pounds of copper, dissolve in water and spray on the tree periodically, you will repress the spread. As soon as you stop spraying the canker comes right back. In 1999 the Brazilians stopped using copper and went back to the eradication program.
