The ultimate goal of any pest management method is to economically reduce the impact of plant disease and to increase crop yield, with minimal disturbance to the environment. Understanding the mode of action of a management measure, as well as the contributing biotic and abiotic processes, provides an important tool for optimizing pest control, predicting its efficacy, and minimizing undesirable side effects. Once the mode of action is known, the control measures can be better adjusted to various situations, thereby increasing the reliability and reproducibility of pest management. Pest control by solarization involves several mechanisms beyond thermal inactivation. This was already apparent in the early days of solarization, since pathogen control was achieved in the lower soil layers where temperatures were not lethal and disease control was found to be higher than that expected from mere thermal inactivation. Soil heating is a major factor in soil solarization, serving as a lethal agent but also as a trigger for other chemical and biological processes. Both the application of solarization and crop growth require moist soil, which serves as an appropriate platform for continuous microbial activities. Indeed, there is some evidence of enhanced beneficial microbial processes in solarized soil that contribute to, and improve, pathogen control, as well as crop development and yield.
