Louisiana Department of Agriculture and Forestry

The Louisiana Department of Agriculture and Forestry (LDAF) is a cabinet-level state agency operating under the authority of the Louisiana Revised Statutes, Title 3, responsible for regulating agricultural commerce, forestry management, consumer protection in food and fiber markets, and pest and disease control across the state. The department is headed by the Louisiana Commissioner of Agriculture and Forestry, an elected constitutional officer serving a four-year term. Its authority spans both regulatory enforcement and direct field operations, making it one of the more operationally active agencies within the Louisiana executive branch.

Definition and scope

LDAF administers state programs across five primary functional areas: agricultural and environmental sciences, horticulture and quarantine, forestry, market development, and consumer protection. The statutory foundation is codified in Louisiana Revised Statutes Title 3 (Louisiana Legislature, LRS Title 3), which grants the department authority to inspect, license, certify, and enforce standards across the agricultural and forestry sectors.

The agency's geographic jurisdiction covers all 64 Louisiana parishes, including high-volume agricultural production areas such as Rapides Parish, Caddo Parish, and Calcasieu Parish. Louisiana's agricultural economy includes approximately 27,000 farms spanning roughly 8 million acres (USDA National Agricultural Statistics Service, 2022 Census of Agriculture), placing substantial regulatory demands on the agency.

Scope boundary: LDAF's authority is limited to Louisiana state law and intrastate agricultural operations. Federal regulatory jurisdiction — including U.S. Department of Agriculture (USDA) programs such as the Farm Service Agency (FSA), Risk Management Agency (RMA), and Animal and Plant Health Inspection Service (APHIS) — operates independently of LDAF. Where federal and state programs intersect, LDAF typically serves as the state cooperator. Interstate commerce in agricultural commodities falls under federal jurisdiction through USDA and the U.S. Food and Drug Administration (FDA). Programs administered by the Louisiana Department of Environmental Quality for environmental permitting of agricultural runoff are not covered under LDAF's mandate, though operational coordination occurs.

How it works

LDAF operates through a network of regional offices and field inspectors organized under its functional program divisions. The core operational workflow proceeds through four stages:

  1. Licensing and registration — Pesticide applicators, grain dealers, commodity dealers, nurseries, and food processors must obtain LDAF-issued licenses before operating. License categories are defined under specific subparts of LRS Title 3; for example, commercial pesticide applicators are regulated under LRS 3:3203.
  2. Inspection and sampling — Field inspectors collect samples of fertilizers, pesticides, seeds, and food products to test against labeled or statutory standards. The department operates the Ag Chemistry and Feed laboratory in Baton Rouge for analytical testing.
  3. Enforcement — Violations trigger administrative proceedings, civil penalties, license suspension, or referral to the Louisiana Attorney General. Civil penalty authority varies by program but is set by statute within LRS Title 3.
  4. Forestry operations — The Office of Forestry deploys 11 district offices and maintains a fleet of firefighting equipment to respond to wildfires. Louisiana averages over 2,000 wildfires annually, affecting tens of thousands of acres (LDAF Office of Forestry).

The Commissioner of Agriculture and Forestry sits on the State Land and Natural Resources Trust and coordinates with the Louisiana Department of Natural Resources on matters involving forested state lands.

Common scenarios

Regulated parties and members of the public interact with LDAF across a defined set of recurring situations:

Decision boundaries

Determining which agency holds jurisdiction depends on the nature of the regulated activity:

LDAF vs. USDA APHIS: LDAF administers state plant pest and disease programs under cooperative agreements with APHIS. APHIS retains federal authority over interstate movement of regulated organisms and federally declared pest emergencies. A nursery shipment moving wholly within Louisiana falls under LDAF; a shipment crossing state lines triggers APHIS jurisdiction.

LDAF vs. Louisiana Department of Health: Food products regulated by LDAF are primarily raw agricultural commodities and unprocessed goods at the farm and first-handler level. Processed food facilities and restaurant food safety fall under the Louisiana Department of Health. Dual licensing situations arise for facilities that process both raw and value-added products.

LDAF vs. Louisiana Department of Wildlife and Fisheries: Timber harvesting on private land is regulated by LDAF's forestry division. Harvesting on state wildlife management areas or public coastal marshes falls under the Department of Wildlife and Fisheries. The geographic boundary between these authorities follows land ownership status, not parish lines.
