This new volume explores the field of microbial biostimulants, a new and emerging field of plant study that emphasizes the benefit of microbes for plants. Microbial biostimulants can have a positive influence on plant health and growth, enhancing agricultural yield and improving resistance to negative environmental changes with zero harmful discharges. This book, Microbial Biostimulants: Biorational Pesticides for Management of Plant Pathogens, explores how microbial-based biopesticides can be used for managing pests and plant diseases as well as for the promotion of growth. It looks at the advantages of employing microbial biostimulants over other pest and disease control methods. It also looks at the application of microbial biostimulants as a response to the modern agricultural need for increased productivity and plant health. This book brings together an extensive collection of information on beneficial microorganisms, including newly introduced microorganisms, their biological activities and specificity, resistance mechanisms to pests, formulation, application in agricultural practices, etc. Key features: Provides a roadmap for using microbial biostimulant practices for pest and disease control as a sustainable approach in agriculture Covers the essential aspects of biorational lines for crop stress management Looks at the use of microbial biostimulants for management of specific diseases, including root-knot disease, various soil-borne diseases, etc. Considers the role of rhizobacteria in plant disease management Microbial Biostimulants: Biorational Pesticides for Management of Plant Pathogens will be extremely useful for students, academicians, researchers, and policymakers in the field of food security and diverse disciplines of agricultural sciences.
