Introduction

Pest resistance is a growing threat to horticultural crop production worldwide. The overuse and misuse of pesticides have led to the evolution of resistant pest populations, making control increasingly difficult and costly. Effective pest resistance management (IRM) is essential for sustaining crop yields, reducing reliance on chemical controls, and minimizing environmental risks. This training course provides horticultural professionals with a comprehensive understanding of the principles and practices of IRM. Participants will learn about the mechanisms of pest resistance, the factors that contribute to its development, and the strategies for preventing and mitigating its impact. The course emphasizes a holistic approach to pest management, integrating cultural practices, biological control, and judicious use of pesticides. Through interactive lectures, hands-on exercises, and case studies, participants will develop the skills and knowledge necessary to implement effective IRM programs in their own horticultural systems. This course aims to promote sustainable pest management practices that protect crops, the environment, and human health.
