Plant protection products are preparations used to:
- protect plants or plant products against harmful organisms (insecticides and fungicides);
- destroy harmful plants or parts of plants or prevent undesired growth of plants (herbicides);
- influence the life processes of plants, other than as a nutrient (growth regulators);
- preserve plant products, in so far as such substances or products are not subject to special provisions on food preservatives.
A plant protection product may only be placed on the market or used if authorised as a plant protection product.
Tukes maintains a register of plant protection products authorised in Finland. No other plant protection products than those included in the register may be sold or used.
