Abstract
Plant protection products (PPPs) are widely used in plant production to prevent plants from several threats and thus ensure the supply with plant based food and animal feed. To minimise adverse effects of PPPs on human and animal health as well as the environment there are strict rules for the authorisation of plant protection, their placing on the market, use and control within the EU. Article 68 of REGULATION (EC) No 1107/2009 [1] points out that the member states shall carry out official controls in order to enforce compliance with these rules. Official controls can follow different ways. This article describes the method of taking samples of soil, plant material, spray solution, etc. and running chemical analysis to monitor and ensure the legitimate application of plant protection products.
