In this series of reports from Ernie Neff, University of Florida geneticist and plant breeder Fred Gmitter tells about seeing healthy blocks of citrus in China surrounded by HLB (greening)-infected groves. He describes how some Chinese successfully manage HLB with timely psyllid control, high density plantings and good tree nutrition. There are discussions of how the China findings might apply to Florida. In the last report, Gmitter says his China experience turned him from a pessimist into an optimist about the future of the citrus industry.
