SAMP can provide a prolonged and
durable effect in the field compared to
heat-sensitive antibiotics. SAMP not
only kills bacteria cells but can also
prime plant immune responses to
prevent/reduce infection. In our greenhouse
trials, SAMP has been shown
to treat HLB-positive trees and inhibit
the emergence of new HLB-infection
in healthy trees. Field trials, which can
take several years, are currently being
initiated in Florida to confirm the
efficacy of SAMP in controlling HLB.
Field trials also include testing multiple
peptide application methods for citrus
growers to prevent and treat HLB.
