Introduction
Eradication of exotic spodoptera in the continental U.S. is essential. Consider
all possible methods—biological, cultural or chemical—before beginning a
program. Your goal is to eradicate the pest while minimizing negative
environmental effects.
Emergency programs
Plant Protection and Quarantine (PPQ) develops and makes control measures
available to involved states. Pesticides must be labeled for use on the site, and
within the state, of application.
If treatments selected or proposed are not in conformance with current
pesticide labels, an emergency exemption can be requested and obtained
under Section 18, or 24(c), special local need (SLH), of FIFRA, as amended.
For additional information, see the Emergency Programs Manual, Section 14.
It is a federal violation to use any pesticide in a manner inconsistent with its
labeling.
Environmental documentation
Obtain all required environmental documentation before beginning. Contact
Environmental Services staff for the most recent documentation.
Treatment guidelines
The treatments suggested below are the minimum recommended to achieve
the program goal of eradication. Continue eradication measures for at least
two life cycles of spodoptera. After the termination of eradication measures,
monitor the success of the program for at least one life cycle of spodoptera.
Timing of applications
Apply an insecticide immediately upon discovery of an infestation. Apply
insecticides in the late afternoon, evening, or at night to coincide with
nocturnal habits of adults and most larvae.
Consider delaying applications if weather reports indicate greater than a 50
percent chance of precipitation within 48 hours after application. If rain
reduces the effectiveness of an application, retreat as soon as the label permits.
