Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture focuses on plant health in agro-ecosystems of various economically important cash and food crops with a concern to promote sustainable agriculture. They have emerged as a key organic tool for enhancing yields. In a natural environment the interactions between plants and phytopathogenic fungi are complex and survival requires a development of resistance to plant diseases. Diversity of Plant Growth Promoting Rhizobacteria (PGPR) diversity depends on the nature of root exudates and soil conditions that affect their interaction with host plants. Novel strategies, such as, applying bioactive natural products against the pathogenic fungus are required to control disease sustainably. Various classes of secondary metabolites including lipopeptides, macrolides, alkaloids, terpenoids and phenolics from microorganisms and plants strongly suppress fungal growth and can also be effective in controlling plant diseases both in vitro and in vivo. The modes of actions of some potential antifungal secondary metabolites against pathogenic fungus are also discussed. Eco-friendly fungal species and their metabolites are excellent agents used for regulating various fungal and bacterial phytopathogens and may have tremendous potential for other applications, and play a key role in enhancing plant tolerance to stress. Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture also covers bovine-based formulations used for sustainable production and nutritional security through horticultural crops, thereby addressing the problems associated with malnutrition and under-nutrition encountered by small and marginal farmers, as well as by families facing resource constraints. These techniques can also improve breathable air, drinkable water, and consumable foods. This book addresses the need to mitigate the health problems of people via organic crop production and to improve the socio-economic status of farmers (especially in developing countries), and to revitalize agricultural sustainability.

Sustainable increase in agricultural production while keeping the environmental quality, agro-ecosystem function and biodiversity is a real challenge in current agricultural practices. Application of PGPR can help in meeting the expected demand for increasing agricultural productivity to feed the world’s booming population. Global concern over the demerits of chemicals in agriculture has diverted the attention of researchers towards sustainable agriculture by utilizing the potential of Plant Growth Promoting Rhizobacteria (PGPR).

More than a century has passed since the first bioformulations were introduced to the market. But there is still much to be done, explored and developed. Though bioformulations offer green alternatives and are important for sustainable agriculture, they make up only a small fraction of the total additions used to enhance crop yields or protect them from pests. There is a great need to develop bioformulations that can promote confidence among end users; accordingly, it is imperative that bioformulations to replace chemicals be reliable and overcome the shortcomings of the past. Bioformulations: for Sustainable Agriculture discusses all the issues related to the current limitations and future development of bioformulations. It examines in detail those bioformulations that include biofertilizers and biopesticides (also commonly known as bioinoculants), presenting a global picture of their development. Further chapters address diverse microbes that are already being or could be used as bioformulations. The book also discusses the techniques, tools and other additions required to establish bioformulations as trustworthy and global solutions. It assesses the types of bioformulations currently available on the market, while also considering the future roles of bioformulations, including the reclamation of marginal and polluted soils. Further, it discusses the current legislation and much-needed amendments.

Today, many economically important agricultural, horticultural and ornamental crop plants are attacked by various soil borne and foliar diseases, resulting in billions of dollars in crop losses. Currently, the most widely used disease management strategy is the use of chemical fungicides. However, the use of these fungicides has encountered problems, such as development of resistance by pathogen to fungicides and rapid degradation of the chemicals. Other factors leading to increased interest in alternatives include the increasing cost of soil fumigation, lack of suitable replacements for methyl bromide and public concerns over exposure to fungicides. Both the agriculture and agri-food sector are now expected to move toward environmentally sustainable development, while maintaining productivity. These concerns and expectations have led to renewed interest on the use of “biologically based pest management strategies”. The green revolution of agriculture brought an enormous increase in food production. It not only made the world self sufficient in food but also gave the world’s scientists and farmers an immense amount of self-respect. Though the green revolution did increase food production, the productivity levels have remained low and increase was achieved at a cost of intensive use of water, fertilizer and other inputs which have caused problems of soil salinity, ground water pollution, nutrient imbalances, emergence of new pest and diseases and environmental degradation.

In the context of rising adverse effects of climate change on agriculture, there is a need for advanced methods and practices to manage soils for production of food and energy. This book presents the latest advances in microbial processes that control plant growth, with focus on genomic tools, microbial interactions with the plant and soils habitats, mobilization of plant nutrients, agricultural waste management, biodegradation, bioremediation, carbon sequestration, land reclamation, plant growth promotion, suppression of plant pathogens, induced systemic resistance and tolerance against biotic and abiotic stresses.
