Private Applicator
Who is a private applicator
In Delaware, a private applicator is certified to use or supervise the use of restricted-use pesticides (RUPs) on land they own or rent, or on their employer's land, to produce an agricultural commodity. The work cannot be for compensation from the property owner; trading labor or services is allowed. The certification belongs to the individual and is not a business license.
Core rules
- Certify before buying, using, or supervising RUPs. Pass the DDA private applicator exam and keep proof of certification current.
- Use only according to the label. The label is enforceable federal and state law: site, rate, PPE, restricted-entry interval (REI), storage, and disposal.
- RUPs may be applied by noncertified workers only under the certified applicator's supervision, and only for the private agricultural operation. The certified applicator remains responsible.
- Keep RUP application records for at least two years under federal rules; Delaware may require additional records. Record product, EPA registration number, amount, date, location, crop or site, and applicator.
- Protect water, pollinators, and sensitive sites; follow Delaware setback and notification requirements that apply to the product and site.
Worked example
A farmer is certified and wants to spray a restricted-use herbicide on 40 acres of rented cropland. That is private use: the land is rented for agricultural commodity production and no custom fee is charged. If the same farmer sprays a neighbor's field for $500, the job is commercial for hire, even though the product and field are agricultural. If the neighbor trades labor instead of paying, the private definition can still apply, but the applicator must keep the records and follow the label.
Traps
Assuming private certification lets you take paid custom work; using an RUP on a home lawn or other non-agricultural site without the right commercial category; letting an uncertified helper spray without supervision; skipping records because the application is “just on my own farm”; ignoring that certification expires and must be renewed.
