Educational Materials - Safe Grow

This section provides tips for those managing an existing lawn or installing a new lawn without the toxic materials restricted by the Safe Grow Zone Ordinance.

Minimum Risk Pesticides

When mechanical pulling of weeds, proper cultural lawn care management practices, and biological controls have failed, then, and only then, should you consider least-toxic chemical products. The Safe Grow Act allows materials designated by the U.S. Environmental Protection Agency as minimum risk pesticides under section 25 (b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which are not subject to federal registration requirements, because their ingredients are viewed as safe for the intended use. Below are some examples of effective products for cosmetic management of lawns.
