Advances in Chemical Protection for Plant Disease Management in Agriculture: From Traditional Practices to Modern Innovations

Abstract

Chemical protection in agriculture has played a pivotal role in safeguarding crops from pests, pathogens, and weeds, thereby sustaining global food production and ensuring food security. This review aims to provide a comprehensive understanding of the evolution, advancements, and future perspectives of chemical crop protection strategies. It traces the progression from traditional practices such as the use of botanical extracts, sulfur, and copper compounds to the modern era of synthetic pesticides, systemic fungicides, and targeted molecular formulations. Advances in agrochemical chemistry and formulation technology have significantly enhanced efficacy, persistence, and selectivity while minimizing phytotoxicity and non-target effects. The review emphasizes the increasing integration of chemical protection within the framework of integrated pest management (IPM), precision agriculture, and sustainable production systems. Furthermore, emerging innovations such as nanotechnology-based delivery systems, RNA interference (RNAi) technology, CRISPR-mediated resistance, and pheromone-based pest control represent a paradigm shift from curative to preventive crop protection. Despite these advances, challenges persist regarding pesticide resistance, environmental contamination, and evolving regulatory frameworks. Therefore, future strategies should focus on developing eco-compatible molecules, optimizing dose dynamics, and integrating chemical and biological approaches to achieve resilient and sustainable agroecosystems.
