POSTHARVEST PATHOGENS AND DISEASE MANAGEMENT
Postharvest diseases caused by microbial pathogens account formillions of dollars in losses of both durable and perishableproduce products every year. Moreover, with consumers increasinglydemanding minimally processed vegetables and fruits--which can beinvaded by human pathogens--there is an imperative need forsuitable protective measures to provide pathogen-free commoditiesthat are free from, or contain only acceptable levels of, chemicalresidues.
Providing details of both conventional and modern moleculartechniques applicable for the detection, identification, anddifferentiation of field and storage microbial pathogens,Postharvest Pathogens and Disease Management:
* Discusses diseases of both durables and perishables duringtransit and storage
* Provides a basic understanding of the effects of handling andstorage practices as well as field conditions and productsusceptibility on the development of postharvest diseases
* Reveals, as a cautionary note, the potential hazards ofmycotoxins with carcinogenic properties that can contaminate fruitsand vegetables
* Contains detailed information derived from elucidative evidenceand disease data in order to explain the infection process andsubsequent stages of disease development
* Helps readers to avoid conditions that favor disease incidenceand spread
* Includes real life examples of disease management strategies tohelp readers develop effective disease management systems suitablefor different ecosystems
* Emphasizes the importance of integrating several differenteffective methods in tandem, including the development of cultivarswith resistance to postharvest diseases; the selection of suitableanalytical methods; and the effective use of biocontrol agents andchemicals
* Presents protocols for numerous techniques and basic methods,making the book a distinctive and highly useful teaching andresearch tool
Postharvest Pathogens and Disease Management offers readers insightinto the principles and methods of avoiding and managingpostharvest diseases of fruit and vegetable products in anefficient, economical, and environmentally feasible manner,allowing producers to sell safer, higher-quality produce to thepublic and prevent the losses associated with postharvest disease.
