pesticide may be defined as any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. It may also be any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant. The wise use of pesticides can contribute significantly to the health, welfare, and quality of human life. However, improper use of pesticides can be a threat to human health and environmental quality. This chapter provides you with a general background in the safe handling of the pesticides used for sewer line root control. Although this manual focuses on products used for sewer line root control, it includes general information about pesticides, what they are, and how to handle them safely. For example, a product that is a degreaser may, in its marketing material, claim to kill or control roots. Products boasting this claim are considered pesticides and are subject to federal and state pesticide laws and regulations. The following sections discuss the differences between general-use and restricted-use pesticides. Applicators using either general- or restricted-use pesticides must comply with specific federal, state, and local rules and regulations that control their safe use. These laws require that restricted-use products such as pesticides containing metam-sodium be handled by or under the direct supervision of a certified applicator. The laws are designed to protect pesticide handlers, customers, the environment, public health, and the systems being treated.
