This book covers the fundamental and applied characteristics of opportunistic (OP) fungi, plant parasitic nematodes (PPN), and plant interactions. Fungal behavior and cultivation, physiological and molecular changes in relation to hosts and pathogens, and the mechanistic aspects of their management strategies are also covered in this volume. In the diverse agro-climatic conditions of the world, PPN has been identified as the most damaging pest to a variety of commercial and agro-important crop plants. Various chemical nematicides have been widely employed to treat nematode infection in recent decades, but use of these chemicals has been restricted due to widespread concerns about human health and environmental safety. In this regard, rhizospheric microorganisms can act as a first line of defense against pathogen attacks on the root and play a critical role in the management of plant diseases caused by PPN. The OP might directly parasitize the PPN by secreting metabolic chemicals that affect the viability of one or more phases of the nematode's life cycle. This book is of interest and useful to teachers, researchers, and professionals working on plant nematology, pathology, ecology, soil science, host-plant interactions, microbial ecology, and industries. Aside from that, this book also serves as additional reading material for undergraduate and graduate students all over the globe, as well as agricultural scientists and policymakers.

Soil provides an excellent niche for the rhizosperic microorganisms and seems to be the hot-spot for the microbial interactions. Among the soil microorganisms Arbsucular mycorrhizal and other phosphate solubilizing microorganisms can promote the plant growth and also very effective against the soil borne diseases. The mycorrhizal fungi have the ability to improve plant vigor, soil quality and also play a crucial role in nutrient uptake, water relations, ecosystem establishment and the productivity of plants. Similarly, phosphate solubilizing microorganisms can profoundly, improve the seed germination, root development, and water uptake by plants. Beside this they can also improve the nutrient uptake or indirectly by changing the microbial balance in favour of beneficial microorganisms in the rhizosphere and can suppress the broad spectrum of plant borne plant pathogens. Considering the importance of these symbionts in the plant disease protection, it came into highlight for research that the combined application of these microorganisms is more beneficial than use of single agent and provides a better management against the soil borne plant pathogens.

Soil serves as an excellent reservoir for the rhizospheric microorganisms and these microorganisms provide front line defense against the pathogens attack to root. Among the different type of soil microorganisms plant health promoting bacteria (PHPB) had the ability to promote the plant growth and also reduced the severity of diseases caused by soil borne pathogens.The bacteria can profoundly, improve the seed germination, root development, and water uptake by plants. Beside this they can also improve the nutrient uptake or indirectly by changing the microbial balance in favour of beneficial microorganisms in the rhizosphere and can suppress the broad spectrum of plant borne plant pathogens.Considering the importance of these symbionts in the plant disease protection, it came into highlight for research that the combined application of these microorganisms is more beneficial than use of single agent and provides a better management against the plant parasitic nematodes.
