Assessment of Integrated Pest Management Strategies in Horticultural Crops
Abstract
Integrated Pest Management (IPM) has become one of the most effective and environmentally sustainable approaches for managing insect pests, diseases, weeds, and nematodes in horticultural crops. Increasing concerns regarding excessive pesticide use, pesticide resistance, environmental pollution, food safety, and biodiversity loss have accelerated the adoption of IPM strategies worldwide. IPM integrates multiple pest management techniques, including cultural, mechanical, biological, physical, genetic, and chemical methods, to maintain pest populations below economically damaging levels while minimizing risks to human health and the environment. Regular pest monitoring, economic threshold levels, biological control agents, resistant crop varieties, crop rotation, habitat management, and judicious pesticide application are fundamental components of IPM programs. In horticultural crops such as fruits, vegetables, ornamentals, and plantation crops, IPM improves crop productivity, enhances produce quality, reduces pesticide residues, conserves beneficial organisms, and lowers production costs through efficient pest management. Modern technologies including Geographic Information Systems (GIS), Remote Sensing (RS), Internet of Things (IoT), Artificial Intelligence (AI), machine learning, drones, and precision agriculture have significantly strengthened pest surveillance, early disease detection, decision support, and site-specific pesticide application. These technological advancements enable timely interventions while improving resource-use efficiency and environmental sustainability. Despite its proven effectiveness, challenges such as inadequate farmer awareness, limited availability of biological control agents, climate variability, and implementation costs continue to restrict widespread adoption. This paper examines the principles and components of IPM, evaluates its effectiveness in horticultural crops, discusses its role in sustainable agriculture, and explores emerging technologies and future prospects for environmentally responsible pest management..
