Plant protection products are safe only if the instructions for use are followed. Before a product comes onto the market, the Ctgb checks its compliance with European and national safety regulations. During the assessment, the possible exposures to substances for humans, animals and the environment are calculated. These calculated exposures are then compared with the safe values. In this way, the risks of using the product are specified. If the assessment indicates that the product can be used safely and that it is effective, then the Board will decide to authorise the product.
