Soil disinfestation generally results in pathogen control; in addition, it can produce biological changes in the soil that may, at a later time, affect the colonization of the rhizosphere and roots by beneficial or deleterious microorganisms. Drastic, nonselective soil disinfestation agents (e.g., steaming or high-dosage fumigation) destroy microbial populations far beyond the scope of the target pathogens. Microbial changes in disinfested soils take place in the soil, as well as in the rhizosphere and plant roots. The chronological sequence of events, namely, pathogen control, biological vacuum, and reinfestation, is expected in disinfested soils in extreme cases of disinfestation. This chapter deals with aspects of the survival and establishment of beneficial microorganisms during and following solarization, which are relevant issues of combining solarization and beneficial organisms during or after this process as a part of IPM. This chapter does not deal with either the screening of beneficial organisms or the testing of their performance as a single measure.
