This book covers all aspects of biotic stress, with detailed focus on elicitors to alleviate adverse effects on plant development and growth. Elicitors are substances that can trigger plants to mount defenses against biotic stressors. Exogenous elicitor application prior to stress events modifies transcription factors, enhancing plant resilience. This book explores the role and applications of elicitors that activate a plant's immune system, leading to increased resistance against biotic stressors. This book also explains how elicitors, both abiotic and biotic, can trigger physiological and morphological responses and phytoalexin accumulation. By reducing reliance on harmful pesticides, this guide fosters a more sustainable and environmentally friendly agricultural approach. "This book is a resource for researchers, agricultural professionals, and farmers seeking solutions to combat biotic stress in crops. Whether you're a seasoned grower or just starting out, this book provides practical strategies and insights to safeguard your crops and achieve a healthier, more productive harvest, empowering you to cultivate a thriving future for your crops and the environment.
