Legislation requires anyone who uses pesticides in the course of employment or business to have received adequate instruction and to be competent in the duties undertaken. This requirement will apply to both the safe use and handling of pesticides and the application method(s) used including sprayers. This training leads to an industry recognised qualification from NPTC. In most cases, each person will need to undertake the Foundation module (PA1) plus a relevant application module. Assessment for the recognised Certificate of Competence usually takes place the following week. PA1 assessments are taken as an online test, lasting approximately one hour.
