Regulated Application & Safe Use

Soil fumigants play an important role in agriculture, nursery, and greenhouse production.

Stringent US and even stricter California state regulations protect the public’s health.

The chemical properties that make soil fumigants so effective in managing difficult-to-control soil pests and diseases require caution and proper handling. Farming chemistry – “plant medicines” – used in soil fumigation are regulated as closely as people medicines. Maybe even more so, since fumigants are also reviewed for their total environmental impact. TriCal is a champion of field performance, public safety, and environmental stewardship.

TriCal is known as an industry leader in following the regulatory requirements:

  • Accumulate at least 40 hours of approved continuing education (CE) every two years before license renewal.
  • Undergo additional ongoing company safety and regulatory training.
  • For more detailed requirements, go to California Department of Pesticide to see Regulation PCA Licensing Requirements.
Regulated & Documented Applications:

Fumigations are well-planned, thoroughly documented, and strictly regulated:

  • A fumigation starts with the PCA providing the grower with a written recommendation addressing 13 specific areas, including worker safety, environmental impact, and a detailed plan for the use of pest management materials.
  • Next, the PCA must

    1. Obtain a Restricted Materials permit,
    2. File a Notice of Intent (NOI) to Apply a Restricted Material,
    3. Complete a Fumigation Management Plan (FMP) detailing everything from soil conditions and application method to buffer zone information and emergency preparedness plan to air monitoring and surrounding area notification.
    4. Finally, the PCA completes the Post Application Summary (PAS) and submits the Pesticide Use Report to the county.
  • For more information about Fumigation Management Plans and soil fumigants, go to US EPA to see the complete Soil Fumigant Toolbox.
Public & Environmental Safety:

Product and application scrutiny keep handlers, applicators, and bystanders safe.

    All applicators and handlers must:

    • Certify completion and fit-test of Personal Protective Equipment (PPE) and respirator training.
    • Closely follow federal and state Worker Protection Standards (WPS).
    • Comply with Good Agricultural Practices (GAPs).

    All soil fumigants are considered Restricted Use Pesticides (RUPs) and undergo rigorous research and testing before getting label approval.
    All product labels contain:

    • How to handle fumigant.
    • Approved application method and rate.
    • Allowable acres for treatment.
    • Entry-restricted period.
    • Mandatory buffer zones.
    • Notification posting requirements.
    • Required personal protective equipment.
    • Applicable tarp removal and re-entry procedures.
