Download or read book Pyrethrum written by John Casida and published by Elsevier. This book was released on 2012-12-02 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pyrethrum: the Natural Insecticide covers the papers presented at the 1972 ""International Symposium on Recent Advances with Pyrethrum the Natural Insecticide"" held in conjunction with the American Institute of Biological Sciences Silver Anniversary Meeting at the University of Minnesota, Minneapolis. It deals with all aspects of pyrethrum, including its history, production, chemistry, biochemistry, toxicology, pharmacology, and agricultural applications. The introductory part addresses the early history of pyrethrum, its recognition as a modern insecticide, and its worldwide production. The chemistry and biochemistry parts discuss the composition, isolation, structure, synthesis, biosynthesis, metabolism, and action on enzyme systems of natural pyrethrins extracted from pyrethrum flower. The book also examines the toxicology of pyrethrum and its constituents to mammals, fish, and wildlife, as well as tests for possible teratogenic, carcinogenic, mutagenic, and allergenic activities. Finally, it discusses the domestic and agricultural applications of pyrethrum. Considering its desirable features, researchers find pyrethrum unsurpassed by any type of synthetic organic insecticide and even by the best synthetic analogs or pyrethroids.

Download or read book Pyrethrum Flowers written by John E. Casida and published by . This book was released on 1995 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over 160 years, pyrethrum has been safely and effectively used as a pesticide the world over. The flowers of this daisy, which contain a mixture of pleasant-smelling esters called the pyrethrins, have highly unusual insecticidal properties. Unique in their ability to repel most insect pests while posing virtually no threat to the environment, pyrethrins have been the subject of great interest to a wide variety of scientists. This book presents for the first time in over twenty years an in-depth look at the many issues surrounding the use of pyrethrins. John E. Casida, a world-renowned authority on the subject, has assembled a group of distinguished contributors to discuss topics ranging from the relationship between pyrethrum and synthetic pyrethroids to cultivation to metabolism to mammalian and environmental toxicology. Along the way, the history of pyrethrum flowers and pyrethrins, the chemistry of active pyrethrin ingredients, the mode of action and resistance, the control of pests, and residues and tolerances are also expertly treated. As safety aspects of pesticides are reevaluated with regard to current regulatory, social, and political implications, pyrethrum has increasingly been seen as the prototype for safe, natural pesticides. Engaging and profusely illustrated, Pyrethrum Flowers is the perfect introduction to the most important natural botanical pesticide. It will appeal to all scientists concerned with pesticides, including botanists, geneticists, biochemists, entomologists, and ecologists.

This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: It must have been some feeling of frustration invoked by the genus loci of big conferences which brought Don Dougall, Mike Fowler, and me over a cup of coffee to think of organizing a small meeting on cell culture metabol ism. The basic aim was to bring people working on "primary metabolism" and those who work on "secondary metabolism" to interact with each other, hopefully to induce some new approaches to utilize the cell culture technique more efficiently in basic research and in its practical application. The out come of this was the small symposium at SchloE Rauischholzhausen near GieEen (Germany), and the reader of this small volume of articles on topics discussed will judge to what extent this aim was realized. Although F.e. Steward was unable to attend the meeting, we were happy that he contributed a review on some important turning points of the cell culture method in the past, and at the end of the book some participants of the meeting attempted some prognosis on possible future developments, summarized by Mike Fowler. It was the wish of our publisher to organize the contributions as a summary of the major topics of research of the individual groups represented at the meeting. Due to this, some readers will certainly feel that important areas of research in the cell culture field are missing. This is regrettable, but space had to be limited to keep this volume at a reasonable price.

Book excerpt: The ATSDR toxicological profile succinctly characterizes the toxicology and adverse health effects information for the toxic substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicological properties. This public health statement tells you about pyrethrins and pyrethroids and the effects of exposure. Pyrethrum is a naturally occurring mixture of chemicals found in certain chrysanthemum flowers. Pyrethrum was first recognized as having insecticidal properties around 1800 in Asiaand was used to kill ticks and various insects such as fleas and mosquitos.

Book excerpt: The global biodiversity and climate emergencies demand transformative changes to human activities. For example, food production relies on synthetic, industrial and non-sustainable products for managing pests, weeds and diseases of crops. Sustainable farming requires approaches to managing these agricultural constraints that are more environmentally benign and work with rather than against nature. Increasing pressure on synthetic products has reinvigorated efforts to identify alternative pest management options, including plant-based solutions that are environmentally benign and can be tailored to different farmers’ needs, from commercial to small holder and subsistence farming. Botanical insecticides and pesticidal plants can offer a novel, effective and more sustainable alternative to synthetic products for controlling pests, diseases and weeds. This Special Issue reviews and reports the latest developments in plant-based pesticides from identification of bioactive plant chemicals, mechanisms of activity and validation of their use in horticulture and disease vector control. Other work reports applications in rice weeds, combination biopesticides and how chemistry varies spatially and influences the effectiveness of botanicals in different locations. Three reviews assess wider questions around the potential of plant-based pest management to address the global challenges of new, invasive and established crop pests and as-yet underexploited pesticidal plants.

Available in PDF, EPUB and Kindle. Book excerpt: Due to the prohibitive cost of synthetic pesticides and the problems of environmental pollution caused by continuous use of these chemicals, there is a renewed interest in the use of botanicals for crop protection. Agricultural entomologists, nematologists, and pathologists the world over are now actively engaged in research into the use of plants to fight agricultural pests and diseases, and to reduce the losses caused by them. Botanical Pesticides in Agriculture reviews the research on botanical pesticides used to combat losses due to pests of agricultural importance, with special attention focused on the use of higher plants. This book will serve as the baseline reference work for future research, and many of the botanicals discussed, such as neem, bael, begonia, pyrethrum, tobacco, karanj, and mahuwa, may become integral parts of pest control programs currently being developed. It is believed that botanical pesticides will minimize the undesirable side effects of synthetic pesticides and help preserve the environment for future generations.

This book was released on 2012-08 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have evolved for over 400 million years and to defend themselves from insect attack many plant species and cultivars have developed an elegant protection mechanisms involving production of insect repellents and even insect toxic substances. Plants which use such mechanisms effectively to keep themselves free of insect infestation are called "insect resistant plants." The exploration and use of such insect resistant plants in order to fight medicinal and agricultural insect pests is an integral part of mankind's history. Use of plant extracts and powdered plant parts as insect repellant and insecticides goes back at least as far as the Roman Empire. For instance, there are reports that in 400 B.C. during Persian king Xerxes' reign, the delousing procedure for children was with a powder obtained from the dry flowers of a plant known as pyrethrum (Tanacetum cinerariaefolium, Compositae).
