Under what condition can an Authorized Assistant supervise up to 6 non-certified assistants?

• A. When performing aerial application.
• B. When performing single stem basal treatment.
• C. When operating during an approved pilot program.
• D. When working in a greenhouse.

Answer: (B)

Supervision ratios are tied to how risky and how predictable the task is. When an Authorized Assistant oversees a single stem basal treatment, the work is localized, highly standardized, and easier to control. That combination allows one supervisor to oversee up to six non-certified assistants because the procedure can be reliably monitored for correct technique, proper handling, and minimizing drift or exposure within a small, defined area. Other tasks carry greater risk or complexity—like aerial application, which covers larger areas and involves more variables—so the supervisory limit is tighter. Greenhouse work and pilot programs have their own rules and limits, which are defined separately but aren’t the condition that permits supervising six assistants in this scenario.
