Abstract
Citrus greening, also called Huanglongbing (HLB), has affected citrus production globally. In Florida, the disease has decimated citrus production area and overall fruit yields. Emerging results show that some nutrients applied in a balanced and constant nutrition (BCN) program alleviate tree stress by improving root health, canopy size and tissue nutrient concentration. In this paper, we discuss the current strategies for managing citrus in Florida, and roles of macro- and micronutrients in citrus and other crops. Further, we discuss the role of macro- and micronutrients in potentially restoring root health and tree performance. We wrap up by discussing future research opportunities on the health and nutrition of HLB-affected citrus trees.
