Book Description
"Fungal rot of grape berries close to harvest cause serious economic losses to grape growers particularly in viticulture regions where rainfall during the ripening period is common. The research documented in this report deals with the organisms responsible for grape berry bunch rots in two sub-tropical regions of New South Wales, the Hunter Valley and Hastings Valley. Once the pathogens were identified, the project investigated some of the properties of these organisms with respect to their biology and possible disease management options for grape growers"--p. 2.

Book Description
In the much anticipated 3rd edition of Grape Pest Management, more than 70 research scientists, cooperative extension advisors and specialists, growers, and pest control advisers have consolidated the latest scientific studies and research into one handy reference. The result is a comprehensive, easy-to-read pest management tool. The new edition, the first in over a decade, includes several new invasive species that are now major pests. It also reflects an improved understanding among researchers, farmers, and growers about the biology of pests. With nine expansive chapters, helpful, colorful photos throughout, here’s more of what you’ll find: •Diagnostic techniques for identifying vineyard problems •Detailed descriptions of more than a dozen diseases •Comprehensive, illustrated listings of insect and mite pests,including the recently emerging glassy winged sharpshooter and Virginia creeper leaf-hopper •Regional calendars of events for viticultural management •Up-to-date strategies for vegetation management

Book Description
Vine nutrition, particularly N application in wine grapes, is well known to enhance vine vigour and consequently grape and wine quality. Less is known about the interactive effects of N and irrigation on wine quality and Botrytis bunch rot incidence and severity. The Australian Wine Industry in its 5-year research plan (2002-07) identified Botrytis management strategies as a key area requiring a novel approach for minimizing fungicide application, which is critical to marketing of Australian wine both for the domestic and export markets. This study investigated the role of N nutrition and irrigation management for improving vine vigour, quality and yield of fruit through changes in canopy density and improving cuticular thickness of berries for Botrytis cinerea control using Chardonnay in two field-based (vineyard) trials and Chardonnay and Cabernet Sauvignon in glasshouse-based trials. In the first and second year vineyard trials, 0,30 and 300 kg ha-1N were applied to the soil either with or without irrigation. Effects of N nutrition on B. cinerea infection were also investigated using varieties Chardonnay and Cabernet Sauvignon in glasshouse trials under controlled conditions. Nitrogen (N) application in the glasshouse trials ranged from 25-400 kg ha-1. A leaf bioassay was developed to investigate the infection on leaves across varying N levels. Additional studies looked at effects of N treatment on the severity of B. cinerea infection in berries and resveratrol (stilbenes) in grape leaves, berries and wine in vineyards. In both vineyards, the N applied did not result in significant changes in canopy density, shoot length, yield, or wine quality parameters (OBrix, pH, acidity, total phenols, and N in berries). Also, no significant differences were seen in different levels of N treatment with respect to B. cinerea severity, and stilbene levels in vines over a 2-year period. In glasshouse trials, low N levels (25 kg ha-1) resulted in reduced shoot vigour, low yields and high susceptibility to infection. In contrast, N applications (200 and 400 kg ha-1) maximized vigour (wet cane weight) and imparted resistance in Chardonnay against B. cinerea infection. In Cabernet Sauvignon, the highest level of N application (400 kg ha-1) proved most beneficial in improving vigour and resistance against B. cinerea infection. Preliminary (qualitative) studies on the wax morphology of the berry surface using scanning electron microscopy (SEM) revealed delayed secondary wax plate formation during the veraison period in some replicates of the high N and no irrigation treatment. Further intensive studies would be needed to explore this observation. Light microscopy studies performed to assess the cuticular thickness of the berry at different N treatments did not show any appreciable changes at different stages of berry growth. Field experimental results have implications for farmers and suggest that in regions where vines and soil are not deficient in N, grape growers could avoid excessive soil application of N fertilisers and irrigation to enhance vine vigour for minimizing B. cinerea infection.

Book Description
The fungal genus Botrytis is the focus of intensive scientific research worldwide. The complex interactions between this pathogen and the plants it infects and the economic importance of the diseases caused by Botrytis (principally grey mould) on more than 1400 species of cultivated plants pre- and post-harvest, render this pathogen of particular interest to farmers, advisers, students and researchers in many fields worldwide. This 20-chapter book is a comprehensive treatise covering the rapidly developing science of Botrytis and reflecting the major developments in studies of this fungus. It will serve as a source of general information for specialists in agriculture and horticulture, and also for students and scientists interested in the biology of this fascinating, multifaceted phytopathogenic fungal species.

Book Description
The book is the result of intensive work of 43 authors, all of them leading scientists in the Botrytis sciences. Each chapter describes a particular aspect of fungal biology and its impact on disease processes and host response. New technologies have arisen that when applied to long-standing problems or to test new hypotheses have been most rewarding and many of these are covered in this book. The chapters are cross linked so that readers can follow associated material.
