Book Synopsis Phytophthora Crown, Collar, and Root Rot of Apple and Cherry by : S. Tianna DuPont
Download or read book Phytophthora Crown, Collar, and Root Rot of Apple and Cherry written by S. Tianna DuPont and published by . This book was released on 2019 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytophthora rots can girdle the scion (collar rot), damage the rootstock just below the soil surface (crown rot), and cause necrosis and death of fine roots (root rot). While generally considered a larger problem in rain-fed growing regions with heavy soils, Phytophthora problems occur in Washington, especially where irrigation water carries the pathogen or where irrigation and overhead cooling practices create wet soil conditions for extended periods. Multiple species of Phytophthora have been implicated in crop damage with P. cactorum and P. syringae two of the more significant species. P. cambivora and P. citricola have also been isolated in Washington from symptomatic trees.

Book Synopsis The Biology and Control of Phytophthora Root and Stem Rot of Apple Rootstocks from Stool Beds by : Carolyn Jean Tidball
Download or read book The Biology and Control of Phytophthora Root and Stem Rot of Apple Rootstocks from Stool Beds written by Carolyn Jean Tidball and published by . This book was released on 1987 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present studies were conducted to better understand the etiology, epidemiology and potential control of the Phytophthora stem root rot as it occurs in apple stool beds. Symptoms of Phytophthora root and stem rot occurred as early as May and continued to develop throughout the growing season. Sunken brown-black lesions were visible on shoots, some of which wilted, or exhibited rust-brown or purplish bronzed leaves. Infected roots were red-brown. Some stem lesions were yellow-brown with narrow dark brown margins forming concentric, wavy-margined rings up the stem. Phytophthora cactorum and P. cambivora were both recovered from the stool beds and identified as the probable causal agents of the disease. P. cactorum was more frequently isolated with peak recovery in early September. P. cambivora recovery peaked in mid summer. Both species were pathogenic at either 15 or 24°C, but P. cactorum was more virulent than P. cambivora at both temperatures and is probably the more active of the two species in the field as well. Fosetyl-Al and metalaxyl applied to apple rootstocks in the field reduced the severity of disease subsequently induced by P. cactorum in an excised stem assay. These field treatments also reduced the development of disease in trees graded as healthy and held in cold storage for 3 to 9 months. Root dipping pre-, post-, or pre- and post-cold storage of trees graded either as healthy or mildly infected, with the chemicals benalaxyl, etridiazol, fosetyl-Al or metalaxyl gave variable results. Any chemical dip treatment reduced disease development compared to the untreated controls, but fosetyl-Al and metalaxyl at 12000 or 4000 ppm, respectively, applied pre-cold storage gave the best disease control over all. The development in apple stool beds of stem and root rot caused by P. cactorum and P. cambivora was reduced in the field by applications of fosetyl-Al and/or metalaxyl applied to trees during the growing season, and reduced further by a root dip before cold storage.

Book Synopsis Oaks in the Urban Landscape by : Laurence Raleigh Costello
Download or read book Oaks in the Urban Landscape written by Laurence Raleigh Costello and published by UCANR Publications. This book was released on 2011 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication offers a comprehensive look at the management of oaks in urban areas. As development moves into oak woodland areas, more and more oaks are becoming "urban" oaks. Oaks are highly valued in urban areas for their aesthetic, environmental, economic and cultural benefits. However, significant impacts to the health and structural stability of oaks have resulted from urban encroachment. Changes in environment, incompatible cultural practices, and pest problems can all lead to the early demise of our stately oaks. Using this book you'll learn how to effectively manage and protect oaks in urban areas - existing oaks as well as the planting of new oaks. Three key areas are addressed: selection, care, and preservation. You'll learn how cultural practices, pest management, risk management, preservation during development, and genetic diversity can all play a role in preserving urban oaks. Arborists, urban foresters, landscape architects, planners and designers, golf course superintendents, academics, and Master Gardeners alike will find this to be an invaluable reference guide.
