Control of soil-borne pathogens with living bacteria and fungi: Status and outlook†

This review addresses some of the current problems with soil-borne pathogens and their economic importance in comparison to the total plant protection market- Possible opportunities for biological control solutions in view of the various constraints of western agricultural production are discussed. More specifically, we address the scientific, economic and conceptual hurdles which have slowed down the development of biocontrol agents. In addition, examples of biological control of soil-borne pathogens which have already reached the market or are likely to be exploited commercially within the next few years are presented. Finally, we speculate on certain developments which might become important for the further commercial development of biological control products.
