Download or read book Crop Protection Under Changing Climate written by Khawar Jabran and published by Springer Nature. This book was released on 2020-08-04 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the impact of important climatic changes on plant pests (including weeds, diseases and insect pests), and their interactions with crop plants. Anthropogenic activities have seriously impacted the global climate. As a result, carbon dioxide (CO2) and temperature levels of the earth are on a continuous rise. The global temperature is expected to increase by a 3°C or more by the end of this century. The CO2 concentration was below 300 parts per million (ppm) before the start of the industrial era; however, recently it has exceeded 400 ppm. This is highest ever in human history. Other than global warming and elevated CO2 concentrations, anthropogenic activities have also disturbed the global water cycle, ultimately, impacting the quantity and distribution of rainfall. This has resulted in drought conditions in many parts of the world. Global warming, elevated CO2 concentration and drought are considered the most important recent climatic changes that are impacting global ecosystems and human societies. Among other impacts, the effects of climatic changes on pests, pest-crop interactions and pest control are important with relevance to global food security, and hence require immediate attention by plant scientists. This book discusses innovative and the most effective pest control methods under an environment of changing climate and elaborates on the impact of drought on plant pests and their control.
Download or read book Herbicide Residue Research in India written by Shobha Sondhia and published by Springer. This book was released on 2018-10-30 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.
Download or read book Grasses as Food and Feed written by Zerihun Tadele and published by BoD – Books on Demand. This book was released on 2018-12-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The grass or Poaceae family includes all cereal crops and forage grasses. Hence, they play a significant role in the economy of both the developed and developing world. Similar to other crop types, grasses are continuously challenged by a variety of environmental constraints. These constraints include a variety of biotic and abiotic stresses, and an enabling environment, which mainly refers to policy-related issues that affect productivity. In this book, the importance of selected cereal crops and grasses as well as associated constraints are presented. In addition, techniques proven to improve the productivity of these groups of crops are discussed. The techniques include variety development, soil and crop management practices, and biological control of fungal pathogens using different types of bacterial strains.

This book was released on 2013-10-04 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global society in the 21st century is facing challenges of improving the quality of air, water, soil and the environment and maintaining the ecological balance. Environmental pollution, thus, has become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation has resulted in the indiscriminate exploitation of natural resources for fulfilling human desires and needs, which has contributed in disturbing the ecological balance on which the quality of our environment depends. Human beings, in the truest sense, are the product of their environment. The man-environment relationship indicates that pollution and deterioration of the environment have a social origin. The modern technological advancements in chemical processes/operations have generated new products, resulting in new pollutants in such abundant levels that they are above the self-cleaning capacity of the environment. One of the major issues in recent times is the threat tohuman lives due to the progressive deterioration of the environment from various sources. The impact of the pollutants on the environment will be significant when the accumulated pollutants load will exceed the carrying capacity of the receiving environment. Sustainable development envisages the use of natural resources, such as forests, land, water and fisheries, in a sustainable manner without causing changes in our natural world. The Rio de Janeiro-Earth Summit, held in Brazil in 1992, focused on sustainable development to encourage respect and concern for the use of natural resources in a sustainable manner for the protection of the environment. This book will be beneficial as a source of educational material to post-graduate research scholars, teachers and industrial personnel for maintaining the balance in the use of natural sources for sustainable development.
