Allelopathy is a common technique in agriculture in which the influence of chemical compounds produced by certain plants on other organisms, also known as allelochemicals, is exploited.
This influence can be positive or negative. There is a wide range of situations and different plants that can be used, always in a totally environmentally friendly way.
Certain plants can be cultivated to inhibit or stimulate the growth or fructification of other plants. The repellent properties of some of them can be used to protect our crops from fearsome pests. It is certainly important to know how to prevent!
