Pesticides and Fertilizer

Pesticides
Municipalities generally may not regulate pesticides or pesticide products. State law preempts local regulation of the registration, sale, use, notification of use, advertising, marketing, distribution, applicator training or certification, storage, transportation, disposal, disclosure of confidential information, and product composition of pesticides. This preemption does not limit a municipality's authority to regulate land use through zoning for pesticide storage facilities or disposal sites, regulate discharges to sanitary sewer systems, or implement pest management plans required by the federal Safe Drinking Water Act. The commissioner may enter into an agreement with municipalities having a population exceeding 250,000 to assist in enforcing the Tennessee Insecticide, Fungicide, and Rodenticide Act. T.C.A. §§ 43-8-114–115; 62-21-118; 62-21-129.

Fertilizer
Municipalities generally may not regulate the registration, packaging, labeling, sale, storage, distribution, use, or application of fertilizer. An exception allows municipalities located in counties having a population exceeding 200,000, according to the 2000 federal census or any subsequent federal census, to adopt local fertilizer regulations. T.C.A. § 43-11-125.
