Implementing Insecticide Sprays for Winter Management of Psyllids

Daniel CooperHLB Management, Psyllids, Tip of the Week

Therefore, most citrus trees do not produce new shoots during this period. These young shoots are essential for the growth of the Asian citrus psyllid (ACP), Diaphorina citri. The ACP is a small sap-feeding insect …
