SUBJECT: Spruce Tree treatment for Tussock Moth
Weather permitting, campus grounds staff will conduct an application of the
insecticide Conserve SC, (Spinosyn A and D), to seven Colorado blue spruce
trees at the northwest corner of the aerospace section of the engineering
complex. These trees are infested with Douglas fir Tussock moth larvae, and
their health and appearance are being negatively impacted to a significant
degree. This application will occur Saturday, May 19, 2012. Conserve SC is a
fermentation-derived organic insect control agent effective against foliar
feeding caterpillars, and is EPA Reg. No. 62719-291.
An outside vendor, Davey Tree Care Co., has been hired to conduct the
applications based on their demonstrated track record of conducting targeted
applications on campus trees.
As a further effort to ensure the highest standard of health and environmental
protection, Facilities Management staff will accompany the contracted
applicators to ensure that only predetermined locations receive treatment,
applications are stopped during high wind gusts and/or sustained wind events,
applications are halted as pedestrians pass and that all necessary precautions
are taken to avoid non-target impacts.
Guidelines for pesticide use are generally described in the campus Pest Control
Policy http://www.colorado.edu/ehs/pdf/pest.pdf . This application is just one
of many tools used as part of an integrated approach to landscape management.
These trees will continue to receive supplemental watering and cultural care,
and will be monitored closely for secondary pest or health problems.
Staff will also be placing yellow application notice flags that will indicate
where the application was made. Law requires that these flags remain in place
for 24 hours after an application. In the interest of keeping the campus
community informed, staff will leave these flags in place for one full week
after the application occurs.
Please do not hesitate to contact me if you should have any questions or
