Technical Abstract: Supplemental nutrition as a part of huanglongbing (HLB) management is being adopted by an increasing number of citrus growers in Florida. The hope is that additional nutrition, especially micronutrients, will extend the productive life of HLB affected trees. Although the approach is recent in the United States, nutrient management for mitigation of HLB symptoms has been practiced in China for many years. Literature review, field surveys, and interviews with Chinese scientists and growers indicate that a nutritional approach, together with other cultural practices such as irrigation, can maintain grove productivity for years depending on the type of citrus species/cultivars, age of the trees, propagation method of the plants, and density of Asian citrus psyllid (ACP) (Diaphorina citri Kuwayama) populations, and other factors. Symptomatic mature pommelo (Citrus maxima Merr) and sweet orange (C. sinensis L. Osbeck) plants can commonly survive and maintain a acceptable level of productivity for an additional 4 to 5 years, even longer, assuming vigorous ACP control. Nevertheless, no consistent evidence supports the notion that nutrient management can maintain productivity of HLB-infected trees in the long term.
