(a) “Feasible alternative” means other chemical or nonchemical procedures that can reasonably accomplish the same pest control function as existing procedures with comparable effectiveness and reliability, taking into account economic, environmental, sociological, technological, and ecological factors, including impact on beneficial and other nontarget organisms, pest resistance to pesticides, and timeliness of control.

(b) “Pest management system” means a systematic approach to pest control that stresses the application of biological and cultural pest control techniques with the selective use of pesticides when necessary to achieve acceptable levels of control with the least possible harm to nontarget organisms and the environment as described in subdivision (f) of Section 11501.
