A Growth-Enhancing Pest Management Option
By Christopher Vincent Particle films can both increase tree growth and reduce Asian citrus psyllid populations. University of Florida (UF) research has found particle films delay infection with the CLas bacterium, which causes HLB. They also enhance growth rates and yield. Particle films do have limitations to efficacy, including being washed off in frequent or heavy rains. Overall, particle films …
New Grapefruit Rootstock, Scion Experiment
The world’s peerless grapefruit grows in the Indian River Citrus District. Balanced with sugar and tart, and a thin rind for easy peeling, the fruit is sold mostly for export to European and Asian markets, where it is a high-price delicacy.

By Brenda Eubanks Burnette I recently came across an article by Frank Kay Anderson in the June 1922 issue of Citrus Industry magazine and found it quite interesting, as I have never seen this version of a grapefruit “preparer.” It also made me wonder if this was one of the first fulfillment programs in the industry. So, if you have …
Does Reducing Psyllids Help When HLB Is Present Everywhere?
By Freddy Ibanez, Nabil Killiny, L. Gene Albrigo and Lukasz L. Stelinski With both Asian citrus psyllids (ACP) and huanglongbing (HLB) distributed throughout Florida groves, there is no longer a need to slow the spread of the disease. So, it is logical to ask whether reducing vector numbers is still something that is worth pursuing, given the investment needed in …
