Editorial: Novel approaches for sustainable crop yield and management of plant-parasitic nematodes

Résumé

Novel approaches for sustainable crop yield and management of plant-parasitic nematodes Plant-parasitic nematodes (PPNs) are a major concern in agriculture as they cause significant crop damage resulting in yield losses and economic losses for farmers (FAO, 2019). For the past 50 years, the control of PPNs has relied heavily on the use of synthetic nematicides and soil fumigants, which have been effective in rapidly controlling nematode populations. However, due to environmental and health concerns, many traditional nematicides have been banned or withdrawn from the market. To achieve sustainable PPN control, it is advisable to adopt control strategies that are safer and more selective. These strategies include the use of bionematicides, biocontrol agents, cultural methods, and plant resistance (Jones et al., 2013). Bionematicides include biochemical antagonists such as natural products or microbial antagonists, which can induce chemical and/or physical damage against PPNs. Biocontrol agents, such as beneficial nematodes, fungi, and bacteria, can then be used to control PPNs (Pires et al., 2022 In conclusion, the adoption of safer and more selective PPN control strategies, such as bionematicides, 89 biocontrol agents, cultural methods, and plant resistance is proving to be a sound alternative the sole 90 reliance on synthetic nematicides. Also, the access to DNA sequencing and to genome-editing tools, 91 and the possibility design new plant protectants are also the for new 92 possibilities for PPNs However, the integration of these strategies is not always 93 straightforward, their effectiveness can vary depending on the specific nematode species and the 94 local environment. The rhizosphere is a complex system that contains thousands of microbial species, 95 and their interactions with PPNs are still not fully understood. Further research is needed to better 96 understand the interactions between PPNs, microbial antagonists, and plant resistance mechanisms in 97 order to develop more effective and sustainable control strategies. 98 99Author contributions 100 M.L.I: conceptualization and writing-original draft.
