Abstract
Environmental problems such as global warming, pollution, and the decline of plant species biodiversity are leading to new social trends and discussions. A relatively new idea of global sustainable development aims to meet societal demands while protecting and enhancing natural resources. The main tools used in the implementation of natural resource protection measures are sustainable development indicators. One of these indicators is the damage caused by the use of synthetic chemicals in agriculture. In Serbia, agriculture is an important sector of the economy with different levels of technological progress, from extensive to intensive. The degree of pollution and its impact on the environment varies according to agricultural production. The challenges faced by modern agricultural production in conditions of technological progress have led to the intensification of production, but have also caused concern about maintaining the natural balance of cultivated land and product quality. The application of innovative technologies for crop protection without the use of chemical agents is a step that should reduce the environmental damage caused. Among the most important natural metabolites and secondary products of aromatic plants used as biopesticides are essential oils. The biological activities of essential oils (EOs) in agriculture have antimicrobial and herbicidal effects. The various bioactive components of the oil determine its action. In nature, they play an important role in protecting plants from bacteria, fungi, viruses and insects. In most weeds, the oils penetrate the cytoplasmic membrane of the cell as typical lipophiles and cause its multilayers of polysaccharides, fatty acids and phospholipids to lose their structure and become permeable. Chlorosis, necrosis, and growth inhibition are symptoms of damage caused by the application of essential oils to plants. Although the physiological effects of the oil are not yet well studied, the importance of its use and other natural metabolites indicates its value for sustainable agriculture.
