Considering the sensitivity of rare microbial taxa to environmental disturbances and their critical roles in ecosystems, it is essential investigate how soil communities (particularly microbes) respond pesticide exposure. In this study, we found that thiazole pesticides significantly reduced severity potato common scab effectively disrupted pathogen's cell membrane integrity. Notably, hierarchical partitioning analysis indicated geocaulosphere constitute key clusters influencing disease incidence. Within bacterial molecular ecological networks, nodes corresponding these generally exhibited higher degrees compared those more abundant taxa. However, exposure number keystone substantially weakened hub status networks. These findings suggest that, although eradicate pathogens, they may also pose a non-negligible potential risk agricultural ecosystems.
