Integrated nematode management (INM), which includes physical, chemical, cultural, regulatory, and biological methods, can be effective in controlling nematode populations but may also be time-consuming and less effective due to natural circumstances and pathogen adaptation. Chemical nematicides are fast-acting, versatile, and cheaper, providing rapid management with broad-spectrum activity. However, reliance on synthetic chemicals has decreased due to their adverse environmental impacts, leading to the emergence of eco-friendly management practices. Biocontrol is a safe and effective approach for managing PPNs; it is not only suppressing PPNs but also enhances plant growth and triggers systemic resistance against various biotic stresses. A diverse array of organisms, including bacteria, fungi, viruses, and protozoans, produce naturally occurring and biodegradable secondary metabolites, offering multiple target sites and a broad spectrum of nematicidal activity against PPNs. The effectiveness of antagonistic microbes may vary according to field conditions, and the release of their nematicidal secondary metabolites into the soil is typically slower compared to the immediate action of chemical nematicides. Antagonistic microbes used in biocontrol have a limited shelf life and require specific storage conditions for viability. Additionally, these microbes may lose viability if exposed to unfavorable environmental factors, such as extreme temperatures or dryness. To overcome these problems, incorporating nanotechnology tools in nematode management can enhance formulation development. By encapsulating these metabolites in nanoemulsion, the solubility and stability of microbial secondary metabolites are improved, enabling targeted delivery, controlled release, and enhanced efficacy while minimizing impacts on non-target organisms and reducing environmental contamination. This review highlights the importance of microbial secondary metabolites, their mode of action in nematodes, and the application of nanoemulsion in nematode management.</div></div>","PeriodicalId":20046,"journal":{"name":"Physiological and Molecular Plant Pathology","volume":"136 ","pages":"Article 102578"},"PeriodicalIF":2.8,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This poses severe food scarcity. Efficient sensory equipment and applications for effectively determining diseases of plants are essential to ensuring agriculture's viability and food production. In modern agriculture, nanotechnology helps to combat nutrient deficiency, promote stress tolerance, and improve the quality and yield of crops. The phytogenic synthesis of nanoparticles that is environmentally harmless, cost-effective, and excellent biocompatibility is considered as best strategy compared to other traditional synthesis methods. Iron nanoparticles (FeNPs) have garnered significant attention among other nanoparticle kinds because of their unique features, which include superparamagnetism, a higher surface-to-volume ratio, a larger surface area, and an easy separation process. FeNPs have good efficiency in mitigating stress caused by abiotic and biotic factors in crops which can enhance their productivity. When biotic and abiotic stress is perceived by plant, it rises the production of ROS, altered the anatomical structures (such as RNA, DNA, protein, organelle), reduced the growth and productivity of plant. In severe condition, plant may die. Application of FeNPs activates the stress related gene expressions their pathways that ultimately upregulate stress related proteins. They also trigger biochemical redox enzymes, osmoprotectants and antioxidant defense mechanism which confer tolerance. It also improves the uptake of minerals and increases photosynthesis, as a result plant resuscitate. FeNPs might raise crop antioxidant levels, boost growth, improve soil nutritional status, and increase tolerance to different oxidative stressors.
