He was quick to add that the nutrition program only works with a strong psyllid control program to help protect new flushes from reinfection.
This spring, Brlansky again collected samples from some of the plots that received nutrient combinations other than the Boyd cocktail and repeated the process.
Results are pending, Rouse says.
“If we can narrow down what are the important parts of this [cocktail], then we can cut the cost to the grower,” he says.
The next step is to collect additional leaf and stem samples for microscopic observation with light and electron microscopes “to see the bacteria and plugging to find out more and provide a description of what’s happening here,” Rouse says.
Brlansky also plans to determine whether the phloem in treated trees is functioning with tests using a fluorescent dye.
A grower advisory group within the Citrus Research and Development Foundation Inc. recently recommended funding Brlansky’s project.
