Bio control Foliar application Inspecting leaves
to create a protected tree, and HLB
resistance. Other strategies include
higher density orchards planned for
shorter tree life span, using interference
RNAs to prevent ACP from picking up
the disease and growing citrus under
protective cover.
Pest Control Districts
Judy Zaninovich, Kern County ACP/
HLB grower liaison said residential
finds of ACP were very high 2015-16.
The county pest control district’s pilot
program for residential citrus has
taken out 2,000 trees near sites where
ACP was detected. There are similar
pilot programs in southern California
counties.
In southern California a total of 1,127
HLB positive trees have been removed.
Last year at this time the number
was 501 trees. This shows the disease
is spreading, but also that CDFA is
improving their detection.
Last year, Zaninovich said, the
potential for a late summer spike in
ACP populations was recognized and
coordinated treatments were done.
Knowing there is the potential for an
upswing in ACP at that time, she said
the plan would be repeated this year.
She said there is also evidence that
nighttime applications may be more
effective.
Irrigation Injection
Best practices for application of
systemic pesticide imidacloprid
delivered via irrigation was discussed
by both Sarge Green, director of
Center for Irrigation Technology at
Fresno State and Rick Leonard of
Bayer.
