Abstract
Biological ‘soil sickness’ is a type of soil disease, which is a part of the fruit tree replant problem (FTRP). Occurrence of FTRP is connected with increasing intensification, concentration and specialization of plant production.
Recent results of ‘soil sickness’ research support that phytopathogenic and/or saprophytic phytotoxic microorganisms may represent important biological components contributing to FTRP. On the other hand, it has been demonstrated that in continuous monoculture of fruit trees, the selection of phytoprotective microorganisms in the soil, maintain the equilibrium with phytopathogens or phytotoxic saprophytes, which help preventing FTRP. The introduction of beneficial microorganisms into the rhizosphere increases the phytoprotective activity of natural microorganisms which, in turn, may be isolated to be used as biopreparations.
Several experiments brought evidence that it is possible to use microbial antagonists and/or other microorganisms, together with other biological means, for the control of FTRP.
