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.
A map of the specific application areas are attached or can be viewed on our City website at: www.go2kennewick.com/DocumentCenter/View/11300/2019-Herbicide-Application-Map
