Postfreeze Citrus Recovery Strategies

Daniel Cooperfreeze, Tip of the Week

By Tripti Vashisth and Prudhvi Vulchi Plant growth regulators (PGRs) have become an important management tool for Florida citrus growers facing the challenges of huanglongbing (HLB). HLB disrupts the tree’s hormonal balance by reducing growth-promoting hormones like cytokinin and gibberellins and increasing stress-related hormones. This imbalance weakens carbohydrate transport, reduces sink strength and accelerates canopy decline. PGRs can help restore …
