Download or read book Predicting Crop Phenology written by Tom Hodges and published by CRC Press. This book was released on 1990-12-26 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting Crop Phenology focuses on an analysis of the issues faced in predicting the phenology of crop plants and weeds. It discusses how these issues have been handled by active crop growth simulation model developers and emphasizes areas such as the role of modeling in agricultural research and the roles of temperature, length of day, and water stress in plant growth. This comprehensive text also discusses modeling philosophy and programming techniques in modeling crop development and growth. It presents up-to-date information on phenology models for wheat, maize, sorghum, rice, cotton, and several weed species. Predicting Crop Phenology reviews important data for agricultural engineers, plant physiologists, agricultural consultants, researchers, extension agents, model developers, agricultural science instructors and students.

This book was released on 2008-10-01 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. Agricultural pesticides, properly used, are essential in supplying the food requirements of the world ever growing population. The use of synthetic pesticides affects the health of human being. The indiscriminate use of pesticides has adversely affected the health of the soil. The residual pesticides in the soil not only affect the soil quality but also the water quality, as they get leached into the ground water. Due to these reasons, role of biopesticides are very important for sustainable agriculture. The use of biopesticides for sustainable agriculture is a complex issue that at times is difficult to comprehend and plan. Biopesticides are usually inherently less toxic than conventional pesticides. They generally affect only the target pest and closely related organisms, in contrast to broad spectrum, conventional pesticides that may affect organisms as different as birds, insects, and mammals. They often are effective in very small quantities and often decompose quickly, thereby resulting in lower exposures and largely avoiding the pollution problems caused by conventional pesticides. Biopesticides, key components of integrated pest management (IPM) programmes, are receiving much practical attention as a means to reduce the load of synthetic chemical products being used to control plant diseases. In most cropping systems, biological pesticides should not necessarily be viewed as wholesale replacements for chemical control of plant pests and diseases, but rather as a growing category of efficacious supplements that can be used as rotation agents to retard the onset of resistance to chemical pesticides and improve sustainability. In organic cropping systems, biopesticides can represent valuable tools that further supplement the rich collection of cultural practices that ensure against crop loss to diseases. Some of the examples of biopesticides are triazino benzimidazol, thiophene sar, pyrazoles, hydroxyacetophenones, benzoylphenylureas, thiadiazolo S triazine etc. It is observed that India occupies a comparatively better position in the arena of biopesticides; in terms of growth of usage, percentage share of the total pesticide market and also in research publications. The driving forces behind this progress are identified as huge research infrastructure (universities and bio control labs) and favourable public support system/policies. Subsequently, it delves on strategies to incorporate the promotion of biopesticides into rural development efforts like recognition of the huge traditional knowledge base and use of biopesticides developed using indigenous technologies. Some of the fundamentals of the book are synthesis of triazino benzimidazol as 1 biopesticides, synthesis and pesticidal activities of thiadiazolo S triazine and imidazol, synthesis and antimicrobial activities of pyrazoles, effects of penconazole on plasma membrane, metabolism of diclofop methyl , bleaching herbicides stimulate maize HMGR activity, soil transformation of acetochlor, propanil degrading amidase activity, inhibition of BTX B binding by RH 3421, KDR type resistance in German cockroach etc. This is the first book of its kind which provides different parameters for manufacturing of biopesticides. The book will not only be resourceful for new entrepreneurs but will also help the technocrats, research scholars and those who willing to know more about biopesticides.

Download or read book Medicinal and Aromatic Plants written by Tariq Aftab and published by Springer Nature. This book was released on 2021-03-27 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before the concept of history began, humans undoubtedly acquired life benefits by discovering medicinal and aromatic plants (MAPs) that were food and medicine. Today, a variety of available herbs and spices are used and enjoyed throughout the world and continue to promote good health. The international market is also quite welcoming for MAPs and essential oils. The increasing environment and nature conscious buyers encourage producers to produce high quality essential oils. These consumer choices lead to growing preference for organic and herbal based products in the world market. As the benefits of medicinal and aromatic plants are recognized, these plants will have a special role for humans in the future. Until last century, the production of botanicals relies to a large degree on wild-collection. However, the increasing commercial collection, largely unmonitored trade, and habitat loss lead to an incomparably growing pressure on plant populations in the wild. Therefore, medicinal and aromatic plants are of high priority for conservation. Given the above, we bring forth a comprehensive volume, “Medicinal and Aromatic Plants: Healthcare and Industrial Applications”, highlighting the various healthcare, industrial and pharmaceutical applications that are being used on these immensely important MAPs and its future prospects. This collection of chapters from the different areas dealing with MAPs caters to the need of all those who are working or have interest in the above topic.

Available in PDF, EPUB and Kindle. Book excerpt: As in previous volumes, readers will find a multidisciplinary forum for communicating knowledge related to the botany, horticulture, and pharmacology of herbs, spices, and medicinal plants. While magical and mystical powers have been associated with these plants through the ages, continued investigations in such areas as production, nomenclature, uses, chemical constitution, and dynamics help elucidate the affiliated chemical and physical processes that contribute to their unique flavor, fragrance, pharmacological, and other bioactive properties. This collection of articles examines the potential of natural products as pesticides, the richness of the Chinese Pharmacopeia, the similarities of Eastern Asian and Eastern North American medicinal plants, the use of borage as a source of gamma linolenic acid, and the botanical nomenclature of medicinal plants.

Download or read book Lives of Weeds written by John Cardina and published by Cornell University Press. This book was released on 2021-09-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lives of Weeds explores the tangled history of weeds and their relationship to humans. Through eight interwoven stories, John Cardina offers a fresh perspective on how these tenacious plants came about, why they are both inevitable and essential, and how their ecological success is ensured by determined efforts to eradicate them. Linking botany, history, ecology, and evolutionary biology to the social dimensions of humanity's ancient struggle with feral flora, Cardina shows how weeds have shaped—and are shaped by—the way we live in the natural world. Weeds and attempts to control them drove nomads toward settled communities, encouraged social stratification, caused environmental disruptions, and have motivated the development of GMO crops. They have snared us in social inequality and economic instability, infested social norms of suburbia, caused rage in the American heartland, and played a part in perpetuating pesticide use worldwide. Lives of Weeds reveals how the technologies directed against weeds underlie ethical questions about agriculture and the environment, and leaves readers with a deeper understanding of how the weeds around us are entangled in our daily choices.
