The horticultural crops, including spices and plantation crops, are known for their enormous benefits, contributing to the country's economy. However, Phytophthora, a genus of Oomycetes class, poses a threat to spice and plantation crops by infecting and damaging them, resulting in yield losses, economic hardship for farmers, and food security concerns, thereby threatening the sustainability of spice and plantation crops. Moreover, Phytophthora has greater adaptation systems in varying environmental conditions. Therefore, eradicating or controlling Phytophthora is a highly challenging process due to the longevity of its infective propagules in soil. Early detection and curative measures would be more effective in managing this destructive pathogen. Additionally, molecular detection using innovative methods such as polymerase chain reaction, reverse transcription polymerase chain reaction, recombinase polymerase amplification, and loop-mediated isothermal amplification would offer reliable and rapid detection. Furthermore, integrated disease management strategies, combining cultural, physical, chemical, and biological methods, would prove highly beneficial in managing Phytophthora infections in spices and plantation crops. This review provides a comprehensive overview of the diversity, symptomatology, pathogenicity, and impact of Phytophthora diseases on prominent spice and plantation crops. Finally, our review explores the current disease reduction strategies and suggests future research directions to address the threat posed by Phytophthora to spices and plantation crops.
包括香料和种植园作物在内的园艺作物以其巨大的益处而闻名,对国家经济做出了贡献。然而,疫霉属(一种卵菌纲真菌)通过感染和破坏香料和种植园作物对其构成威胁,导致产量损失、农民经济困难以及粮食安全问题,从而威胁到香料和种植园作物的可持续性。此外,疫霉在不同环境条件下具有更强的适应系统。因此,由于其感染性繁殖体在土壤中的寿命较长,根除或控制疫霉是一个极具挑战性的过程。早期检测和治疗措施在管理这种破坏性病原菌方面会更有效。此外,使用聚合酶链反应、逆转录聚合酶链反应、重组酶聚合酶扩增和环介导等温扩增等创新方法进行分子检测将提供可靠且快速的检测。此外,结合文化、物理、化学和生物方法的综合病害管理策略在管理香料和种植园作物中的疫霉感染方面将被证明非常有益。本综述全面概述了疫霉病害对主要香料和种植园作物的多样性、症状学、致病性和影响。最后,我们的综述探讨了当前的病害减少策略,并提出了未来的研究方向,以应对疫霉对香料和种植园作物构成的威胁。
