Definition of plant biologicals

In the Plant Biologicals Network we define plant biologicals as naturally derived products that can serve as biostimulants, biocontrol agents, resistance inducers or biofertilizers. They derive from naturally occurring microorganisms, plant extracts or other organic matter. They include:

  • macrobials (predators and parasitoids: e.g. mites, spiders, bugs, lady beetles and wasps)
  • microbials (bacteria, fungi, oomycetes and vira)
  • biologically derived products (plant extracts, lipopeptides and proteins)

Plant biologicals can, among other things, lead to growth increase in the plant, disease control, soil health improvement, and enhancement of plant nutrient uptake.
