This book is designed for the Postgraduate M.Sc. (Nematology) course titled “NEM 507: Nematode Interactions with Other Organisms (2+1).” It provides a comprehensive overview of nematode interactions with various plant disease-causing organisms, including fungi, bacteria, viruses, and insect pests, offering a holistic perspective on their ecological roles and impacts.
One of the key challenges in nematode-disease complex studies is the lack of clear and comprehensive study materials. This book addresses this need by offering wellstructured explanations, illustrative diagrams, and up-to-date research insights, making it a valuable resource for both students and educators at undergraduate and postgraduate levels.
Features
• Provides an up-to-date review of research findings, case studies, and recent advancements in nematode-disease complex interactions, serving as a one-stop resource for learners.
• Offers practical information on the diagnosis and management of nematodeassociated diseases, making it useful for farmers, extension workers, and researchers.
• Highlights the multidisciplinary nature of nematode interactions, fostering collaboration among experts in plant pathology, entomology, microbiology, and ecology.
This book aims to enhance understanding and application of nematode interaction studies, benefiting students, educators, and professionals engaged in plant health management.
