TREATMENTS IN 2010
Two areas have been identified for treatment this spring.
Trapping results in 2009 have revealed enough information to define
treatment boundaries for gypsy moth infestations growing in Richmond and
Harrison. An aerial application is proposed for the Richmond
infestation while surviving moths from the 2009 aerial application in
Harrison will be treated using a ground spray. The Harrison
treatment is located
south of the village of Harrison Hot Springs on primarily agricultural
land on the road to Harrison Lake. The spray formulation chosen
for use on both treatment areas is approved for use on
organic farms.
The treatments will usually take three separate applications.
The aerial application may take one or two mornings to complete
while the ground spray should be completed in one day. Treatment dates and times
will be provided to the local media, schools, registered day cares,
seniors care facilities, and hospitals and will be posted on this web site, listserve e-mails, and on the gypsy moth
information line (1-866-917-5999 (24 hr information line)).
No other areas of the Province are being treated in 2010.
Pesticide Use Permit Application
A Pesticide Use Permit Application was submitted to the Ministry
of Environment on October 27th, 2009 according to the conditions
described in the
Integrated Pest Management Act and
Regulation.
SPRAY DATES
Application dates
(up to four applications between April 25th to
June 30th, 2010) are selected based on the estimated peak
emergence and development rates of gypsy moth
caterpillars. These dates are generated by
a sophisticated insect growth model developed by
the Canadian Forest Service. Since these rates are temperature
dependent, the dates may change with the input
of real temperature data vs. estimated
temperatures based on historic averages. Poor weather
(rain, high winds) may cause cancellation of the
spray but it will resume as soon as the weather
and other conditions become favourable. Every
effort will be made to provide notification of
changes to the schedule when they occur.
Updates will be given to local media,
posted on this site, sent via
listserve e-mail, and on the outgoing phone
message on the toll-free gypsy moth information
line (1-866-917-5999)
