Requires use of uniform silver flags to mark certain pesticide applications.

This bill (A 3719) requires all commercial pesticide applicators in New Jersey to mark treated areas with uniform silver flags. The flags must be silver, same size/type, display bilingual (English/Spanish) information, and remain visible for at least 72 hours after application. It also prohibits using silver flags for other purposes like dog fences or utility lines to prevent confusion. The Department of Environmental Protection must create implementing rules, and the law takes effect one year after enactment.
