The biological mechanisms underlying the invasion and spread of Solidago canadensis were elaborated, along with control strategies and advances in comprehensive utilization. Its invasive spread was attributed to several biological mechanisms, including the formation of polyploid complexes, combination of sexual and asexual reproduction, production of allelochemicals, and synergistic interactions with microorganisms. Integrated management of this invasive plant should be implemented based on its life history and invasion characteristics, combining agricultural, biological, physical, and chemical methods for comprehensive control. Agricultural control was implemented through tillage, crop rotation, plastic film mulching, and planting competitive species to suppress its growth. Bio-ecological management was carried out by introducing natural enemies or replacement plants to restore ecological diversity. Physical removal (manual uprooting, mechanical excavation) was preferably conducted during the mid-to-late growth stages, with careful attention paid to rhizome treatment to prevent regrowth. Chemical eradication was achieved using herbicides such as glyphosate, applied according to habitat-specific needs to avoid resistance development. Management was implemented in phases with multi-measure coordination, emphasizing ecological safety and sustained control. Regarding comprehensive utilization, the plant was found to be rich in active components (diterpenes, triterpenes) with anti-inflammatory and antimicrobial activities, indicating high potential for pharmaceutical development. Its high crude protein and fiber content made it suitable as quality green forage or silage for ruminants like cattle and sheep. The high fiber content also rendered it an ideal raw material for papermaking and fiberboard production, as well as for conversion into biomass energy. Through comprehensive utilization such as materialization, feed production, and substrate application, its invasive impact could be mitigated, achieving both economic and ecological benefits. At present, challenges remain in the control and utilization of this invasive plant, including accelerated spread due to human activities, high costs of existing control technologies, and technical bottlenecks in resource utilization. In the future, an integrated management system combining scientific, policy, and social efforts needs to be established. This article provides a reference for the control and resource utilization of Solidago canadensis.
