Trunk Injection Could Deliver the Kill Shot to HLB
There are many materials that will kill the bacteria (Candidatus Liberibacter asiaticus) that causes HLB. The challenge has been getting these materials to the place where the bacteria lives in citrus trees — the phloem. Some believe trunk injection might do the trick, but it is an expensive and labor-intensive practice that has limited any breakthroughs so far. During the …

He reported on his work at a Feb. …
Trial Confirms Benefits of IPCs
Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …
