Pesticides are substances that are primarily used to keep the crops healthy and to prevent them from being destroyed by pests or disease. They are categorised as insecticides (against insects), herbicides (against plants, such as weeds) and fungicides (against fungi). Synthetic pesticides are based on various artificially produced substances or combinations thereof, which have a toxic effect on the respective organisms. However, most pesticides affect not only harmful organisms but also other plants and animals, including beneficial ones. The active substances in pesticides can also accumulate in the food chain or pollute bodies of water, including our groundwater. As a result, pesticides can ultimately impact humans and their immediate environment as well.
