Book Synopsis Spurred Anoda by : James Michael Chandler

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Spurred Anoda: A Potential Weed in Southern Crops In our Stoneville study, mature seed capsules and seeds were observed 13 weeks after emergence (may 29, Peak capsule and seed production occurred 17 weeks after emergence (fig. One plant produced capsules with seeds. In North Carolina, spurred anoda grown at densities of 10 plants per meter of row produced an average of 159 seed capsules per plant, with an average of 14 seeds per capsule (solano et al. L976b). The differ ences in seeds per plant between the Mississippi and North Carolina studies were due to intraspecific competition, or plant density. Since spurred anoda germinates and emerges in the field until October and since the mature seed develops a hard impermeable coat, it is important to know the number of mature seeds produced by plants emerging during the late summer and early fall prior to frost. At Stoneville, plants emerging from seeds planted July 27 produced 828 and mature seeds by October 11 and 24, respectively (table When planting was delayed 2 weeks, only 376 seeds per plant were produced by November 5. Spurred anoda planted August 24 and September 14 produced only 39 and 12 seeds per plant, respec tively, by November 5. Even so, the small quan tities of seed produced by November 5 from August 10 and later plantings were adequate to produce substantial plant populations the following year.

Book Synopsis Microbial Control of Weeds by : D.O. TeBeest
Download or read book Microbial Control of Weeds written by D.O. TeBeest and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is appropriate at this time to reflect on two decades of research in biological control of weeds with fungal plant pathogens. Some remarkable events have occurred in the last 20 years that represent a flurry of activity far beyond what could reasonably have been predicted. In 1969 a special topics review article by C. L. Wilson was published in Annual Reviews of Phytopathology that examined the literature and the potential for biological control of weeds with plant pathogens. In that same year, experiments were conducted in Arkansas that determined whether a fungal plant pathogen could reduce the infestation of a single weed species in rice fields. In Florida a project was under way to determine the potential use of a soil-borne plant pathogen as a means for controlling a single weed species in citrus groves. Work in Australia was published that described experiments that sought to determine whether a pathogen could safely and deliberately be imported and released into a country to control a weed of agricultural importance. All three projects were successful in the sense that Puccinia chondrillina was released into Australia to control rush skeleton weed and was released later into the United States as well, and that Colletotrichum gloeosporioides f.sp. aeschynomene and Phytophthora palmivora were later both marketed for the specific purpose of controlling specific weed species.
Book Synopsis Regulating Pesticides in Food by : National Research Council
Download or read book Regulating Pesticides in Food written by National Research Council and published by National Academies Press. This book was released on 1987-02-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about health effects from exposure to pesticides in foods is growing as scientists learn more about the toxic properties of pesticides. The Delaney Clause, a provision of the Food, Drug and Cosmetic Act, prohibits tolerances for any pesticide that causes cancer in test animals or in humans if the pesticide concentrates in processed food or feeds. This volume examines the impacts of the Delaney Clause on agricultural innovation and on the public's dietary exposure to potentially carcinogenic pesticide residues. Four regulatory scenarios are described to illustrate the effects of varying approaches to managing oncogenic pesticide residues in food.
Download or read book Desert Weeds written by Garry Rogers and published by Springer Nature. This book was released on 2020-10-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature’s EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.

Book excerpt: Herbicides are one of the most widely used groups of pesticides worldwide for controlling weedy species in agricultural and non-crop settings. Due to the extensive use of herbicides and their value in weed management, herbicide research remains crucial for ensuring continued effective use of herbicides while minimizing detrimental effects to ecosystems. Presently, a wide range of research continues to focus on the physiology of herbicide action, the environmental impact of herbicides, and safety. The authors of Herbicides, Physiology of Action, and Safety cover multiple topics concerning current valuable herbicide research.

Available in PDF, EPUB and Kindle. Book excerpt: For the past 20 years, the first edition of this text has been widely cited as authoritative academic reference. The latest edition continues the tradition set by the original book, and covers weed science research that has been published since 1980. This book aims to reduce the instance of research duplication—saving scientists and supporting institutions time and money. Not only does the second edition of Weed Crop Competition review, summarize, and combine current research; it critiques the research as well. This text has the potential to accelerate advancements in weed crop competition, which remains an important factor that affects crop yields. Scientists in foreign countries where access to literature is often limited or nonexistent, will find the information in this text invaluable. Weed scientists, crop scientists, plant ecologists, sustainable agriculturists, and organic agriculturists will be well-pleased with this long overdue and much needed new editionWeed Crop Competition provides a unique reference that reviews, summarises and synthesizes the literature published concerning research on this topic. The first edition has been one of the most frequently cited sources in weed science for the past 20 years. The second edition covers the significant body of literature that has been published since 1980. Originally intended to survey existing research, the intent of the book is to reduce the instance of research duplication, thus saving scientists and their institutions time and money, and expediting advancements in weed crop competition, an important factor affecting crop yields. Scientists in foreign countries where access to the literature is often limited or non-existent, find the information an invaluable resource. This long overdue and much needed new edition rejuvenates the tradition set by the original book.
