What to know
Idaho Code § 22-3420 bars using or recommending a pesticide inconsistently with its labeling except as a rule allows, and ISDA permits label deviations only where EPA or state law does. Faulty equipment, false records, lending your license and selling outside the original container are also barred. A licensed private applicator's employee may use an RUP under that applicator's direct supervision. For professional RUP work, on-site supervision means the supervisor is at the site with visual contact, over no more than two noncertified people, who need WPS handler and equipment training within twelve months and may not fumigate, apply by air or, under 18, do professional work; their training records are kept three years, and mixer-loaders get annual training. Professional records are kept two years and list wind speed and direction, location and, for apprentices, the supervisor's name and license number; RUP records go to the customer within 30 days. With no label wind limit, don't spray in sustained winds over 10 mph. Outside the listed crop exceptions, bee-toxic sprays on blooming crops are limited to three hours before sunset through three hours after sunrise; low volatile esters near homes stop above 80°F; aerial phenoxy work needs a smoke column, and unless waived, aerial high volatile ester 2,4-D stays five miles from susceptible crops and hazard areas. Drift off target is prohibited. Storage is locked, fences six feet, signs readable at 25 feet; rinsate stays out of underground tanks. Chemigators use only chemigation-labeled products and check every four hours. Damage reports are due within 60 days or before 25 percent of the crop is harvested.

- AAllowed for general use pesticides only
- BAllowed if the customer agrees to it in writing
- CProhibited only for restricted use pesticides

Prohibited, except as provided for by rule. Use inconsistent with labeling is a prohibited act for every pesticide, unless a rule provides otherwise; customer consent doesn't change that.
