Download or read book The Truth About Organic Gardening written by Jeff Gillman and published by Timber Press. This book was released on 2008-02-01 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gardeners tend to assume that any organic product is automatically safe for humans and beneficial to the environment—and in most cases this is true. The problem, as Jeff Gillman points out in this fascinating, well-researched book, is that it is not always true, and the exceptions to the rule can pose a significant threat to human health. To cite just one example, animal manures in compost can be a source of harmful E. coli contamination if imporperly treated. Gillman's contention is that all gardening products and practices—organic and synthetic—need to be examined on a case-by-case basis to determine both whether they are safe and whether they accomplish the task for which they are intended. Ultimately, Gillman concludes, organic methods are preferable in most situations that gardeners are likely to encounter. After reading this eye-opening book, you will understand why, and why knowledge is the gardener's most important tool.

Book excerpt: Garden Myths examines over 120 horticultural urban legends. Turning wisdom on its head, Robert Pavlis dives deep into traditional garden advice and debunks the myths and misconceptions that abound. He asks critical questions and uses science-based information to understand plants and their environment. Armed with the truth, Robert then turns this knowledge into easy-to-follow advice. - Is fall the best time to clean the garden? - Do bloom boosters work?- Will citronella plants reduce mosquitoes in the garden?- Do pine needles acidify soil?- Should tomatoes be suckered?- Should trees be staked at planting time? - Can burlap keep your trees warm in winter?- Will a pebble tray increase humidity for houseplants? "Garden Myths is a must-read for anyone who wants to use environmentally sound practices. This fascinating and informative book will help you understand plants better, reduce unnecessary work, convince you to buy fewer products and help you enjoy gardening more."

Download or read book Diseases of Trees and Shrubs written by Wayne A. Sinclair and published by Ithaca, N.Y. : Comstock Pub. Associates. This book was released on 1987 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.
Download or read book Understanding the Powdery Mildew Disease of the Ornamental Plant Phlox written by Coralie Farinas and published by . This book was released on 2020 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of plant germplasm has tremendous potential to help address the many challenges that the field of plant health is facing, such as climate change continuously modifying the regions of previously known disease occurrence. The worldwide trade of the plant genus Phlox represents an important revenue for the horticultural industry. However, Phlox species are highly susceptible to the fungal disease powdery mildew (PM), and infected materials shipping across borders accelerate the risk of disease spread. Through collaboration with laboratories in the U.S., we investigated the genotypic and phenotypic diversity of a PM population to better understand its capacity to adapt to new environments and new resistant hosts. To do this, we developed tools to grow and study PM pathogens of Phlox in vitro, and then used whole genome comparison and multilocus sequence typing (MLST) analysis to study the genetic structure of the population. Additionally, we explored Phlox germplasm diversity to identify a range of plant responses to PM infection by comparing disease severity progression and length of latency period of spore production across a combination of Phlox species and PM isolates in vitro. Consistent with the literature, our results suggest that compared to most plant pathogenic fungi in the Ascomycota, Golovinomyces magnicellulatus, causal agent of PM, has larger genomes (about 130 Mb) with high repetitive content (about 40%) and a fewer number of protein-coding genes (about 8000). We found a lack of population structure and genetic diversity, despite diverse phenotypic responses to Phlox germplasm screening. Interestingly, we identified 7 putative secreted proteins, which are predicted to be involved in the infection process, that are differently distributed between the G. magnicellulatus genomes analyzed. We hypothesize that variation in predicted secreted proteins is at the basis of the differences observed in genetic and phenotypic diversity. Our results also suggest the presence of qualitative and quantitative resistant traits in Phlox germplasm. This research explored the genome variation and evolutionary potential of Phlox PM pathogens to infer durability of host resistance, which are key tools to face plant health's future challenges.
