Dodders ( spp.; Convolvulaceae) are parasitic weeds that pose major challenges to agriculture due to their ability to infect a wide range of host plants, extract nutrients, and transmit pathogens. Their control is especially challenging because of the seed longevity, resistance to herbicides, and the capacity for vegetative regeneration. Mechanical methods such as hand-pulling or mowing are labour-intensive and often ineffective for large infestations. Chemical control is limited, as systemic herbicides often affect the host species equally, or even worse than the parasite. Current research is exploring biological control methods, including allelopathic compounds, host-specific fungal pathogens, and epiparasitic insects, though these methods remain largely experimental. An integrated approach that combines prevention, targeted mechanical removal, and biological methods offers the most promising path for long-term management. Continued research is essential to develop effective, sustainable control strategies while exploring possible beneficial uses of these complex parasitic plants. The present review aims to thoroughly summarise the existing literature, emphasising the most recent advances and discussing future perspectives.
菟丝子(菟丝子属;旋花科)是寄生性杂草,因其能够侵染多种寄主植物、获取养分并传播病原体,给农业带来了重大挑战。由于其种子寿命长、抗除草剂以及具有营养繁殖能力,对其进行防治尤其具有挑战性。诸如人工拔除或割草等机械方法劳动强度大,对于大面积侵染往往效果不佳。化学防治也受到限制,因为内吸性除草剂通常对寄主植物的影响与对寄生植物的影响相当,甚至比对寄生植物的影响更严重。目前的研究正在探索生物防治方法,包括化感化合物、寄主特异性真菌病原体和重寄生昆虫,不过这些方法在很大程度上仍处于试验阶段。一种将预防、有针对性的机械清除和生物方法相结合的综合方法,为长期管理提供了最有前景的途径。持续开展研究对于制定有效、可持续的防治策略以及探索这些复杂寄生植物可能的有益用途至关重要。本综述旨在全面总结现有文献,强调最新进展并探讨未来前景。
