Abstract

Due to the damaging effects of root-knot nematodes on crops and the dangerous effects of chemical nematicides on both people and the environment in Egypt, the purpose of this study was to assess the power of polysaccharides and polyphenol extracts as well as their nano-forms from marine algae (Laurencia papillosa and Dilophys fasciola) used as eco-friendly alternatives for the control of Meloidogyne incognita. The nano-forms of algal extracts efficiently suppressed M. incognita egg hatching and increased juvenile mortality compared to the control. The tested treatments effectively decreased galls and egg masses of tomato roots compared to the control in the field. Dilophys fasciola extract and its nano-form showed promising nematicidal activity compared to L. papillosa extract. Generally, algal treatments boosted tomato plant defense system against M. incognita by triggering the production of some biochemical constituents such as phenolic compounds, polyphenol oxidase and chitinase enzymes. Consequently, the productivity and quality parameters of tomato fruits significantly increased.

乳头月桂和筋膜月桂生物合成纳米提取物对番茄根结线虫（Meloidogyne incognita）的抗虫潜力

由于根结线虫对农作物的破坏作用以及化学杀线虫剂对埃及人和环境的危险影响，本研究的目的是评估从海洋藻类（Laurencia papillosa 和 Dilophys fasciola）中提取的多糖和多酚及其纳米形式作为生态友好型替代品对防治黑线蝇（Meloidogyne incognita）的威力。与对照组相比，纳米形式的海藻提取物能有效抑制 M. incognita 的卵孵化并增加幼虫死亡率。与田间对照相比，测试处理能有效减少番茄根部的虫瘿和卵块。与 L. papillosa 提取物相比，Dilophys fasciola 提取物及其纳米形式显示出良好的杀线虫活性。一般来说，藻类处理可促进酚类化合物、多酚氧化酶和几丁质酶等生化成分的产生，从而增强番茄植物防御系统的能力。因此，番茄果实的产量和质量指标都显著提高。

期刊介绍： Phytoparasitica is an international journal on Plant Protection, that publishes original research contributions on the biological, chemical and molecular aspects of Entomology, Plant Pathology, Virology, Nematology, and Weed Sciences, which strives to improve scientific knowledge and technology for IPM, in forest and agroecosystems. Phytoparasitica emphasizes new insights into plant disease and pest etiology, epidemiology, host-parasite/pest biochemistry and cell biology, ecology and population biology, host genetics and resistance, disease vector biology, plant stress and biotic disorders, postharvest pathology and mycotoxins. Research can cover aspects related to the nature of plant diseases, pests and weeds, the causal agents, their spread, the losses they cause, crop loss assessment, and novel tactics and approaches for their management.
