The incidence progress of HLB depends on the local and regional control of ACP and inoculum
sources
The low accomplishment, coordination and
synchronism of citrus growers on regional
control of ACP and elimination of diseased
trees favors the infestation of groves with
HLB management with infectious ACP and
increases the probability of new infections.

Understanding and managing resistance, including novel methods, for pathogen and pest control.
Concentration of diseased trees at the edge of citrus groves indicates that the primary infection
by migrant vector is the most important drive of the HLB epidemics
The main subject of research is how to avoid
or minimize the primary infections, specially at
the grove edge:
-Coordinated vector control (Alert System)
-External actions of inoculum removal or ACP
control
-Strategies at the grove edge to avoid ACP
penetration (planting direction, repellents, barriers)
-Strategies to avoid inoculation by the vector
(vector control with less impact in the
environment, no residue, no selection of resistant
insects at the grove edge)
-Strategies to minimize crop damage (prolong
grove life span)

Both diseases are controlled with chemical applications
Pest resistance to chemicals is a big issue Few molecules available and the restrictions to use them has increased
Low expectative of new molecules development by chemical companies
Real need to research alternative methods
