Nanotechnology-Based Innovations for Pest Management: A Review

Abstract

Nanotechnology is emerging as a transformative tool in modern agriculture, providing innovative and sustainable solutions for pest management. Traditional chemical pesticides, while effective, often result in environmental contamination, pest resistance, and health risks to humans and beneficial organisms. Nanotechnology-based strategies such as nano formulated pesticides, nano sensors, and nanocarriers offer improved efficiency, controlled release, and precise delivery of active ingredients. These technologies enhance pesticide solubility, reduce application frequency, and limit adverse effects on non-target organisms. Metallic nanoparticles like silver, copper, and zinc oxide possess strong antimicrobial and insecticidal properties, whereas plant-based and biopolymer nanoparticles provide eco-friendly, biodegradable alternatives. In parallel, nano   sensors support early pest detection and real-time field monitoring, enabling precision farming and informed decision-making. Despite their advantages, several challenges hinder large-scale adoption. Concerns include potential toxicity to non-target species, environmental accumulation, absence of standardized safety guidelines, and inadequate regulatory frameworks. Economic barriers such as high production costs, limited infrastructure, and low farmer awareness  further restrict implementation. Future advancements should focus on smart nanocarriers with stimuli-responsive capabilities, integration of nanotechnology with gene-editing tools like CRISPR for developing pest-resistant crops, and comprehensive lifecycle assessments to evaluate long-term ecological impacts. Global policy harmonization, enhanced funding for translational research, and improved stakeholder training are essential to bridge the gap between innovation and practical application. With advancements in scientific understanding and regulatory clarity, nanotechnology has the potential to revolutionize pest management by offering safer, more efficient, and environmentally resilient crop protection systems. This review emphasizes current advancements, practical applications, limitations, and future prospects of nanotechnology in pest control.
