Does the pesticide you are using have a Dual-Notice requirement?
WHAT IS MEANT BY "DUAL-NOTICE"?:
Some pesticides have additional requirements. These pesticides ask that workers should be warned orally as well as posting the site.
For example, the Counter SmartBox 20G [EPA Reg 5481-562] it states "Notify workers of the application by warning them orally and by posting signs at entrances to treated areas."
WHERE DO I FIND THIS?
You find this in the "Agricultural Use Requirements" box. This is a box that has to be on all pesticides labeled for agriculture. This box is usually in the first three pages of the label. This is were you also find the Restricted Entry Interval (REI).
