Abstract: | During the last 15 years a great amount of information has been accumulated on the ecology and physiology of soil-borne plant pathogens around the world. Despite this, very few cases of applied biological or cultural control have been reported. Although soil-borne plant pathogens are widely spread and economically important, only a small fraction of plant pathologists and soil microbiologists has devoted full time in the applied phases of biological control. The number of publications on applied control during the last 10 years in two journals surveyed is exceptionally small. The status of applied biological control of root diseases is considerably less favorable than the situation in entomology where much progress has been made during the last 10 years. The status of biological control (narrowly or broadly defined) of soil-borne pathogens is described here and several examples of applied control are cited. Future prospects for research on the ecology and biological control are also discussed. |
