What to know

Nevada licensees apply only in their licensed categories, with other applicators under immediate supervision by someone licensed in that category, and only when climatic, pest and crop conditions are proper, keeping material confined to the premises. Measuring devices are calibrated to the smallest unit, mixtures kept uniform, equipment cleaned, undiluted pesticide locked up, service kits kept from children, containers secured in vehicles, and spill cleanup paid by the licensee. Records of each property treated are kept 2 years; aerial and agricultural ground records include temperature and wind at start and finish, structural records the amount and concentration of diluted mixes, and those two fields file monthly reports by the 15th, even for idle months. Spills over 1 gallon or 4 pounds are phoned in within 24 hours, poisonings within 48. Unlicensed helpers may not sign invoices, reports or contracts. Unregistered materials and off-label purposes are banned. Vehicles show the business name and license number on both sides in 2-inch letters and carry absorbent, potable water and a complete label; diluted service containers show the number as derived from the product. Empty containers are removed or safeguarded. Beekeepers get 24 to 72 hours' notice; rodenticides go where children and pets can't reach them; restricted-use supervisors check in hourly at night and must be present for a trainee's restricted-use work; fumigation needs two people until aeration ends. Neonicotinoids may not be used on plants outside commercial agriculture.
