Uspješna aplikacija pesticida omogućuje učinkovitu zaštitu bilja, ali i sprečava kontaminaciju okoliša i operatera sredstvima za zaštitu bilja. Preduvjeti uspješne aplikacije pesticida su educirani operateri i ispravni strojevi za aplikaciju pesticida (prskalice, orošivači i dr.). Ispravni strojevi za aplikaciju pesticida ispunjavaju uvjete propisane standardom ISO 16122. Korištenje tehnički ispravnih strojeva za aplikaciju pesticida je i zakonska obveza. Strojno pogonjene prskalice i orošivači (bez leđnih prskalica) podliježu obvezi tehničkog pregleda svake tri godine. Za nove strojeve prvi pregled vrijedi pet godina. Pregled prskalica sastoji se od: pripremnih radnji, vizualnog pregleda ispravnosti pojedinih komponenti i mjerenja parametara neophodnih za uspješan rad prskalice. Successful application of pesticides enables effective plant protection, but also prevents contamination of the environment and operators with plant protection products. Prerequisites for successful pesticide application are trained operators and correct devices for pesticide application (sprayers, mist blowers, etc.). Correct devices for pesticide application meet the conditions prescribed by the ISO 16122 standard. The use of technically correct devices for pesticide application is also a legal obligation. Sprayers (without knapsack sprayers) are subject to a technical inspection every three years. For new devices, the first inspection is valid for five years. Inspection of sprayers consists of: preparatory actions, visual inspection of the correctness of individual components and measurement of parameters necessary for the successful operation of the sprayer.
