Annual city-wide herbicide application for noxious weed control is slated to start on or around April 5. Application vehicles will be operating between midnight and 6:00am, Monday through Friday, through the months of April and early May. The primary focus will be to control weeds in the curb/gutter line and gravel shoulders on all of the City’s main roadways.
A yellow dye is mixed with the herbicide to assist with the application. The yellow dye will fade in three to four weeks and application areas are safe for people and pets to enter once the application is dry. If there is inadvertent contact with wet herbicide, it is recommended to remove contaminated clothing and rinse skin immediately with plenty of water for 15-20 minutes.
