Post-harvest Pathology


Book Description

As a collection of papers that includes material presented at the 2008 International Congress for Plant Pathology, this text features research right at the leading edge of the field. The latest findings are particularly crucial in their implications for fruit production; an important market sector where in some areas up to 50 per cent of the crop can be lost after harvest. While post-harvest fruit treatments with fungicides are the most effective means to reduce decay, rising concerns about toxicity have led to the development of alternative approaches to disease control, including biological methods, the subject of three chapters of this book. With several new techniques requiring modification of current post-harvest practices, it is more important than ever to stay abreast of the latest information. Other chapters deal with the mechanisms of host fruit and vegetable resistance, fungal pathogenicity factors and their relationship with the host response, and a number of subjects related to disease assessments before harvest as well as their relationship to the postharvest treatment of fruits and vegetables. The book also includes several useful case studies of crops such as kiwifruit and peaches, where different approaches at the pre- and post-harvest levels are combined to good effect. With food production issues gaining an ever higher profile internationally, this text makes an important contribution to the debate.

Advances in Postharvest Pathology of Fruits and Vegetables


Book Description

Fruits and vegetables are an important part of a healthy diet. However, one third of fruit and vegetables are lost after harvest every year. Most losses are caused by pathogen (mostly fungi) infections, which lead to postharvest decay. In addition, some postharvest fungal pathogens can produce toxic secondary metabolites (i.e. mycotoxins) during their infecting periods. Mycotoxin contamination may cause serious food safety issues. At present, the use of synthetic fungicides is still the main means to control postharvest diseases. However, the development of resistance in fungal pathogens to fungicides and the growing public concern over the health and environmental risks associated with high levels of pesticides in fruits and vegetables have urged researchers to develop alternative methods of disease control. A deeper understanding of the infecting mechanisms of postharvest pathogens will provide great insight into developing new controlling strategies.




Post-Harvest Physiology and Crop Preservation


Book Description

Emphasis in agricultural research for many years has concen trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop·for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world where modern transportation, storage facilities, and marketing technology are widely used, post-harvest technology requires a large input of energy which increases costs considerably. There fore, losses are more significant and the ability to provide fresh fruits and vegetables, out of season, at reasonable costs will depend on reduced post-harvest losses throughout the marketing chain from the farm gate to the ultimate consumer. The reduction in post-harvest losses depends on proper use of current technology and further developments derived from a broad spectrum of scientific disciplines. Biochemistry, plant physiology, plant pathology, horticulture, agronomy, physics, engineering and agricultural economics, all provide knowledge which has been useful and will be useful in the future for improving post-harvest technol ogy and crop preservation. This volume records the Proceedings of the NATO Advanced Study Institute on Post-Harvest Physiology and Crop Preservation, held at Sounion, Greece, April 28 - May 8, 1981.
