Biological plant protection

What is biological plant protection?

Every agricultural or garden crop is a new, and therefore still unstable, ecosystem created by human hand. The key energy resource in this system is the crop itself, so it often leads to a mass propagation of organisms that benefit from these plants, and many of these organisms become pests. The pest population collapses once the nutrient sources are depleted or if the pests are consumed by other organisms as energy sources themselves. Both phenomena develop over time.

Therefore, the aim of plant protection measures is always to prevent the mass propagation of pests at an early stage. In addition to weeds and fungal infections, insects in particular afflict the crops. Biological plant protection uses natural defence mechanisms to control the pests. Indeed, the term biorational pesticides has been coined to differentiate these alternative measures from the use of synthetic chemical pesticides.
