From the reviews of the seventh edition:

"Horst (Cornell) has revised and updated this handbook periodically ... and it continues to be a fine reference for hobbyists and professionals. ... this handbook is a necessary resource for those interested in plant diseases and their control. Summing Up: Highly recommended. All levels." (L. M. Delserone, Choice, Vol. 46 (3), November, 2008)

"‘Westcott’s Plant Disease Handbook’ is one of the bibles for plant pathologists, since it provides the reader with a huge amount of information. … the reader will find many details about plant diseases and their causal agents. … this book can be recommended as a unique reference work for everybody professionally working as a gardener or plant pathologist." (Andreas Kortekamp, European Journal of Horticultural Science, Vol. 73 (6), 2008)

"This notable reference encompasses the whole of plant pathology, dissecting the subject with flair and substance. … Although botanists and botanical researchers comprise the obvious target market for Westcott’s Plant, this text would … also be indispensable to florists and nursery operators as a general reference." (The Electric Review, January/February, 2009)

"Westcott’s Handbook … a standard work of reference in any library dealing with plant subject material. … The layout of the page is crystal clear and there are 90 illustrations including 16 colour plates showing damaged plants and fruits. … specialist organizations such as botanic gardens and research institutes should have access to a copy … ." (Marilyn Mullay, Reference Reviews, Vol. 23 (1), 2009)
