From the Tampa Bay Tribune:
Local citrus growers are taking part in a coordinated effort to reduce the Asian citrus psyllid population, a pest responsible for spreading citrus greening disease, said Ray Royce, executive director of the Highlands County Citrus Growers Association.
The U.S. Department of Agriculture report and the Division of Plant Industries conduct surveys, and according to a recent report, the results have been positive, he said.
The survey concluded that citrus groves where coordinated spraying efforts took place had extremely low levels of the pest. Those that had not taken part had higher levels of the psyllid.
"At roughly the same time, they are using the same chemicals," he said.
What they are trying to avoid with the "area-wide control program" is having several neighboring groves spraying different chemicals, which allows the insect to develop resistance, he said.
