Biological herbicides based on extracts and essential oils of medicinal plants Abstract The use of herbicides has long been considered the most efficient method of weed control in agricultural production all over the world. However, the long-term use of agrochemicals has several negative effects on crops and the environment. In recent years, the development of new products based on bioactive compounds for the biological control of weeds has become important because it helps to reduce the use of synthetic compounds and herbicides in agriculture. Synthetic herbicides can lead to adverse effects such as human diseases and also disrupt the environment due to their movement in the air and persistence in different environments. It seems that the use of natural molecules is a very good alternative to maintain sustainable agriculture without the negative side effects of synthetic herbicides. In this context, extracts and essences of medicinal plants and their components are known thanks to their biocidal activities. Essential oils are an important source of biologically active compounds, oxygenated terpenes, and mono and sesquiterpenes play the main role in the phytotoxicity of essential oils. Essential oils and their components, mainly terpenoids, as pure or mixed natural compounds, can be good candidates for new biological herbicides or as raw materials for new synthetic herbicides due to their structural diversity and strong phytotoxic activity.
