Microbes are used in biopesticides and biostimulants. The definition of biopesticides includes microorganisms, and beneficial arthropods; biopesticides are developed for the control of biotic stresses which are caused by pests and diseases. Biostimulants influence the plant’s responses to abiotic stresses. The market for both categories of products is described. An overview of the biopesticides in Europe is given as well as their targets and crops. Critical failure and success factors in terms of commercialisation are discussed . The implementation of a product in an integrated crop management system needs to be investigated in order to develop guidance for proper use. Limiting factors and promoting trends determine the growth of the markets for these products. Continued growth is expected since alternatives to chemicals are demanded by legislation and consumer demand for residue-free food. Products based on bacteria are anticipated to increase the most for disease and insect control as well as for plant growth.
