Pesticide Licensing and Professional Credentials for Tree Care Services

To legally apply pesticides (including growth regulators like ethephon/Florel for fruit suppression) for hire, you must obtain a state pesticide applicator license. Requirements vary but typically involve:

Licensing Pathway

1. Contact your State Department of Agriculture (or equivalent) for categories, exams, and fees.
2. Attend training. Most state Extension services offer prep courses for the core and category exams (e.g., Ornamental & Turf, Right-of-Way).
3. Pass written exams. Core (general standards) + category-specific.
4. Maintain license. Continuing education units (CEUs) required for renewal.

Professional Credibility: ISA Certified Arborist

• Commitment to ethics and continuing education.

• Specialty horticultural distributors (e.g., SiteOne, Helena, local ag-chem suppliers)
