As the trees become symptomatic for HLB, an imbalance of plant hormones can be observed in the leaves. This hormonal imbalance exacerbates the symptoms and can lead to more stem-dieback, poor vegetative growth, and fruit drop. Ultimately leading to reduced bearing wood, thus resulting in yield losses and tree decline. Thus, the use of growth-promoting hormones can be beneficial in boosting growth in HLB-affected trees. This article will discuss using three PGRS-cytokinin, auxin, and gibberellic acid (GA) on HLB-affected sweet oranges to improve their growth and productivity.
