The use of conventional pesticides has raised significant concerns due to their adverse effects on human health and the environment. In response, there has been a growing interest in developing safer and more eco-friendly alternatives. This chapter explores the concept of green pesticides as a sustainable solution to pest and disease management. Green pesticides, derived from natural sources or synthesized using eco-friendly methods, offer effective control of pests while minimizing harm to non-target organisms and ecosystems. Green pesticides encompass a diverse range of products and approaches, including botanical extracts, microbial agents, natural predators, and pheromones. Moreover, there is a need to incorporate different cultural practices along with green pesticides to enhance pest control while reducing reliance on chemical inputs. However, the efficacy of green pesticides depend on several factors, including pest species, crop type, environmental conditions, and regulatory considerations. Therefore, ongoing research and innovation are essential to optimize the performance and scalability of these eco-friendly alternatives. Overall, this chapter underscores the potential of green pesticides as a safe and sustainable approach to pest and disease management in sustainable agriculture
Plant disease causes losses estimated for 20-40 per cent of global crop. Climate change has a very complex effect on plant-pathogen interactions, since environmental conditions affect the whole disease triangle: they modify plant susceptibility, the biological cycles of parasites and pathogens, and hostpathogen physiology and interactions. Innovative plant protection strategies in horticultural crops encompass a wide range of techniques and approaches aimed at safeguarding plants from pests, diseases, and environmental stresses in a sustainable and effective manner. These strategies are essential for ensuring the productivity, quality, and resilience of horticultural crops while minimizing negative impacts on the environment and human health. Climate change, including increased temperature, CO levels, acid rain, and tropospheric O 3 2 , stresses plants and lowers their pathogen response. While higher CO 2 reduces stomata density, acid rain and O weaken cuticle protection, aiding pathogen entry.
Food security is paramount for developing any nation reliant upon sufficient crop production. The decline in crop production significantly impacts food security, leading to an imbalance between global food demand and agricultural output. Multiple factors contribute to reduced agricultural productivity, including abiotic factors like water scarcity, poor soils, and unsuitable temperatures, as well as biotic factors such as pests, diseases, and weeds attacking crops. These challenges result in inefficient input utilization and decreased crop yields, ultimately threatening food security. Pests, diseases, and weeds profoundly impact plant health, causing substantial losses in crop production. Geospatial technology is employed throughout the agricultural cycle, from initial crop health assessment to forecasting disease outbreaks. Despite the significant challenges global and local agriculture face in achieving optimal outputs and securing food for the world population, the wealth of geospatial data and technological advancements plays a crucial role. They aid decision-makers in formulating strategies to combat various pests and diseases affecting plant health and food crops, thereby contributing to improved agricultural outcomes and food security. This chapter provides a comprehensive appraisal of existing literature to elucidate the role of geospatial technologies, encompassing Geographic Information System (GIS), remote sensing, and the Global Navigation Satellite System (GNSS), which are utilized for data collection, mapping, analyzing distribution, and predicting events related to plant health.
Sustainable agricultural production is endangered by several ecological factors, including biotic & abiotic stresses. Biotic stress is the stress as a result of damage done to an organism by other living organisms. The agents of biotic stress are fungi, bacteria, virus, nematodes, insects, weeds & other plants which reduces quality and production of crops. These challenging environmental factors may have adverse effects on future agriculture production. Breeding resistant cultivars is considered as the best strategy to mitigate the effect of biotic stress. It is durable, economical & environment friendly and provide broad-spectrum resistance. Widely cultivated but susceptible genotypes can be improved by introgression of resistance genes from donor genotype into the background of recurrent genotype by different breeding strategies. In modern agriculture, conventional crop-breeding strategies alone are inadequate for achieving the increasing population’s food demand on a sustainable basis. The advancement of molecular genetics and related technologies are promising tools for the selection of new crop species with resistance genes. Transfer of several genes or quantitative trait loci (QTL) with potential characteristics into a single widely cultivated genotype is possible through the process of marker assisted selection (MAS). Gene pyramiding through MAS have accelerated the development of durable resistant/tolerant lines with high accuracy in the shortest period of time. With marker assisted backcross breeding (MABB), a major gene can be precisely targeted, the genome of the recurrent parent can be recovered fast, and linkage drag can be reduced. Genomic selection (GS) allows selection for multiple traits directly in the genome. These techniques help in identifying plants with two or more genes by employing gene-linked markers without the need for repeated testing in each generation during the development of pyramided lines and hence shorten the time of breeding program.
While the fourth agricultural revolution has been sparked by technological advancements, humans still face many challenges in achieving agricultural resilience to meet the demands of the world’s expanding population, including declining croplands, depleting water supplies, the negative effects of climate change, and more. On the one hand, food and dairy products are in increasing demand due to the growing population. On the other hand, an increasing number of variables pose a threat to food security and sustainable food production, including globalization, climate change, scarce land and water resources, unsustainable land management techniques, pests and diseases becoming resistant to chemical pesticides, and the emergence of pathogens that have adapted to new hosts. The integration of geographic information systems (GIS), remote sensing, and artificial intelligence (AI) in geospatial approaches offers a solid foundation for the sustainable management of agricultural resources with the goal of boosting agricultural output. These days, local, regional, and worldwide agricultural production uses these sophisticated instruments more and more. Growers have been more interested in implementing precision agriculture during the past ten years. Precision agriculture is a crop-management method that takes into account the temporal and geographical heterogeneity of soil and crops within a field. Another agricultural technique that is being promoted as a future development that will enable the world’s population to be fed sustainably is precision agriculture. The broad use of geographic methods for agricultural resource management, including crop disease monitoring and pest infestation control, is the main topic of this chapter.
Plant disease management technique applicable these days are predominantly relies on hazardous synthetic chemicals that are efficiently deleterious to the human and environment as well. Crop loss every year due to plant pathogen and pest is ranging 30–50%. Nanotechnology, proven advantageous and can offer positive environmental impacts over these harmful chemical pesticides by reducing toxicity, increasing the feasibility of pesticides which are normally baffling in water and improving longevity. Now a days and in coming year, it becoming one of the rapidly growing, advancing and most fascinating technological sciences in many disciplines like medicine, science, technology and more importantly in agriculture, to protect crop from different kinds of pest and pathogen on which most of India’s population is completely dependent. This chapter briefly describe the introduction, role and impact of nanotech in management of plant disease. It is considered as modern technology in facing these widespread destructive challenges and causes in controlling in plant disease. In this chapter we tried to summarize the importance of nanotech in sustainable agriculture and application of various nanoparticles (NPs) in the management of plant disease. NPs can be produced by distinct practices, biological and chemical are one of them important methods. Biological method is widely and commercially used. Also, shortly describe the historical background for some NPs types. This chapter briefly focus on the synthesis of some compounds of NPs, for example silver NPs, silver and silica silver etc and their influence on plant disease also briefly describe the working principle of AgNPs against microorganism. NPs may act in accordance with chemical pesticides. Because of microscopic size, NPs have wide scope in virus control in plant. Now day’s biosensors are used for the quick and precise pathogen detection and diagnosis. Regardless of immense scope of NPs application in managing the diseases of plant, there are precise apprehensions, weakness and risk associated with the utility of NPs in agriculture. It is necessary to be figured out on primacy basis prior to trade of NPs in agriculture.

In recent years, the integration of geo-spatial technology has emerged as a promising approach to address these challenges by enabling more accurate monitoring, prediction, and management of pests and diseases. The integration of geo-spatial technology in pest and disease management within agricultural practices represents a significant stride towards precision agriculture. This chapter delves into the innovative application of geospatial tools in identifying, monitoring, and mitigating pests and diseases, thereby optimizing crop yield and quality while minimizing environmental impact. Beginning with an overview of the challenges posed by pests and diseases in agriculture, the chapter highlights the limitations of traditional methods in effectively addressing these issues. It then explores how geo- spatial technology, encompassing Geographic Information Systems (GIS), remote sensing, and global positioning systems (GPS), revolutionizes pest and disease management by providing real-time, spatially explicit data. The discussion extends to the utilization of satellite imagery and aerial drones for early detection and monitoring of pest infestations and disease outbreaks. Through case studies and examples, the efficacy of geo-spatial technology in mapping pest distribution patterns, predicting outbreaks, and implementing targeted interventions is elucidated.
Agriculture plays a pivotal role in India’s economy, it shares 18.2 % (202324) in country’s GDP at current prices and employs 42.3 % of the Indian workforce, particularly in rural areas, making it one of the largest sources of livelihood (Anon., 2024). With 1.41 billion peoples, India is the world largest populous country and agriculture is crucial for ensuring food security. India’s agricultural exports also significant in boosting its economy through generating foreign exchange of 53 billion dollars in 2023 and contributing around 11.8% to total exports (Statista, 2023). India is the largest producer of milk, millets, banana, sapota, cashew nuts, coconuts, tea, ginger, turmeric, black pepper and second largest producer of wheat, rice, sugar, groundnut and in the world (APEDA, 2024). The sector also provides raw materials for many industries, such as textiles and food processing. India achieved self-sufficiency in food grains after Green Revolution, using introduction of high-yielding varieties (HYVs) of crops, especially wheat and rice, chemical fertilizers, pesticides, and improved irrigation techniques, which dramatically increased crop productivity. The improved productivity also helped to increase farmers’ incomes, raise living standards in rural areas, and support the development of rural infrastructure. Moreover, surplus food production allowed India to build buffer stocks, which could be used to manage food shortages or price fluctuations.
Soil health management plays a pivotal role in sustainable agriculture and directly influencing plant growth, crop productivity and environmental quality. Healthy soils are essential for nutrient cycling, water retention and supporting a diverse array of microorganisms that contribute to plant resilience. However, modern agricultural practices, including the excessive use of chemical fertilizers, monoculture cropping and improper irrigation, have degraded soil health, leading to nutrient imbalances, reduced organic matter and soil erosion. This has sparked a growing awareness of the need for effective soil health management strategies that not only maintain but enhance soil quality. Innovative tools for soil health management are reshaping plant protection strategies by promoting holistic approaches that focus on maintaining and improving the biological, chemical and physical properties of the soil. These tools range from organic amendments and biofertilizers to advanced diagnostic technologies such as soil microbial profiling, remote sensing, and precision agriculture techniques. Together, they offer a comprehensive framework for addressing soil-related constraints and enhancing plant resistance to pests and diseases.

Chickpea (Cicer arietinum L.) is the third most important pulse crop grown all over the world. Chickpea is infested by an average of about 60 insectspests, of which gram pod borer, Helicoverpa armigera (Hubner) (Lepidoptera : Noctuidae) is known to be the key pest. Helicoverpa is responsible for causing up to 90 % damage in chickpea due to its regular occurrences. In order to manage this problem, growers are tempted to increase the amounts of pesticides, but indiscriminate or injudicious use of pesticides has resulted in residues in the food chain, pesticide resistance, and pest resurgence, in addition to causing harm to non-targeted beneficial organisms and the environment. Here, we reviewed the sustain- able approaches to reduce the incidence of pod borer and achieve sustainability in chickpea production systems through the adoption of an integrated approach involving host plant resistance, good agronomic practices, and judicious use of chemical and biological methods.
