Registered technicians must be re-registered and receive update training on an annual basis. Non-certified Applicators Applications may be made by an individual who is neither certified nor a registered technician, if and only if that individual is under the direct supervision of a certified applicator who is physically present and within sight of the application being made. The PA Pesticide Hypersensitivity Registry, which is maintained by the PDA, is a list of people who have been verified by a physician to be excessively or abnormally sensitive to pesticides. Commercial and public pesticide applicators must contact anyone on the registry whose listed location is within 500 feet of a pesticide application site. Notification requirements are met if the information is placed on a telephone answering device, or information is given to an adult contacted by dialing any of the listed telephone numbers.
Additional testing is required if the applicator intends to use a restricted use fumigant.
In this case, the applicator must obtain a special permit by passing a written examination specifically related to the type of fumigation which will be made. If an applicator's certification expires, further use of pesticides that would otherwise be permitted is prohibited. However, the applicator has up to one year to reinstate the certification by obtaining the necessary recertification credits and paying the appropriate fees. If the certification has expired longer than a one year period, reexamination is required for recertification. Private applicators are required to maintain records only for applications of restricted use pesticides.
