Prevention is the best way to protect your lawn, trees, flowers and vegetables from disease.  Purchase plant types that are resistant to disease, keep them healthy and clean up plant debris that can be home to disease organisms. Before selecting a product that claims to “protect” your plant, read the label carefully. It may include toxic chemicals that can be dangerous to you, your kids and pets, wildlife and the environment.  

Stop, Think, and Protect what matters by choosing the least toxic pest control alternative.

YardSmartMarin works to raise awareness and reduce the use of pesticides in Marin County.
