Here is an usually well-researched NYT article on the efforts to control citrus greening. The obvious solution is to apply modern plant genetics to develop a commercial orange that is resistant to the bacterium. Southern Gardens Citrus has been funding five labs that are making excellent progress on GM solutions. But the delays in the tortuous regulatory jungle may have less financial impact on growers than the unfounded fears that have been spread by anti-GMO activists. Could the Greenpeace campaign against modern agriculture end up destroying the Florida orange industry?
The call Ricke Kress and every other citrus grower in Florida dreaded came while he was driving.
“It’s here” was all his grove manager needed to say to force him over to the side of the road.
The disease that sours oranges and leaves them half green, already ravaging citrus crops across the world, had reached the state’s storied groves. Mr. Kress, the president of Southern Gardens Citrus, in charge of two and a half million orange trees and a factory that squeezes juice for Tropicana and Florida’s Natural, sat in silence for several long moments.
“O.K.,” he said finally on that fall day in 2005, “let’s make a plan.”
In the years that followed, he and the 8,000 other Florida growers who supply most of the nation’s orange juice poured everything they had into fighting the disease they call citrus greening.
To slow the spread of the bacterium that causes the scourge, they chopped down hundreds of thousands of infected trees and sprayed an expanding array of pesticides on the winged insect that carries it. But the contagion could not be contained.
In his office is a list of groups to contact when the first G.M.O. fruit in Florida are ready to pick: environmental organizations, consumer advocates and others. Exactly what he would say when he finally contacted them, he did not know. Whether anyone would drink the juice from his genetically modified oranges, he did not know.
But he had decided to move ahead.
Late this summer he will plant several hundred more young trees with the spinach gene, in a new greenhouse. In two years, if he wins regulatory approval, they will be ready to go into the ground. The trees could be the first to produce juice for sale in five years or so.
Whether it is his transgenic tree, or someone else’s, he believed, Florida growers will soon have trees that could produce juice without fear of its being sour, or in short supply.
