The Vegetable Pathosystem Ecology, Disease Mechanism, and Management

Variability in vegetable pathogens is a critical issue, particularly in changing environments, as it presents challenges to accurate diagnoses and proper management. This book focuses on the diverse ecology of phytopathogens, covering the varying disease categories (acute, chronic, and emerging), the mechanisms involved in disease development, pathogen variability, and disease management. The book also discusses the preharvest and postharvest challenges that arise due to these phytopathogens.Key Features:• Provides an overview of phytopathogens that affect vegetables in various environmental conditions• Discusses how to manage vegetables affected by specific pathogens• Offers eco-friendly approaches to prevent postharvest diseases• Presents a comprehensive guide to identifying and addressing numerous diseases for individuals in the fields of horticulture
