Description / Abstract:


DESPITE THE FACT that potatoes are immensely important as a food crop worldwide, and that the diseases, pests and disorders that affect them have received a great deal of investigation, there are few texts that have attempted to describe and encompass the crop protection problems in any depth. Only relatively recently has it been possible to reproduce high- quality colour photographs, integrated within text, in books. The Colour Handbook is one of the first to achieve this for the potato crop, and covers the majority of diseases, pests and disorders that occur.

High-quality photographs are important where accurate visual diagnosis is required. Where possible, and where they were available, ‘typical' symptoms are represented here. Of course, there is always variation in the symptoms of any potato problem, but we have tried to find photographs that will help to distinguish one disease, pest or disorder from another.

Identification by comparison with photographs is only a start to confirming diagnosis. Confirming that the observed symptoms accord with a verbal description is an essential next step on the road to correct identification. In this book, each disease, pest or disorder has a detailed description of the symptoms and, where relevant, the vectors that transmit the disease.

While photographic and written symptoms can support an initial diagnosis, its confirmation will depend on isolating the micro-organism/pest involved or, in the case of disorders, establishing that no living pest or disease is involved. Absolute confirmation would depend on reproducing the symptoms, by infecting a healthy plant with the isolated microorganisms or pest. However, disorders are more difficult to reproduce. This last step of absolute confirmation is not often undertaken, unless a problem is perceived as a new one, or a new strain of a disease or pest is suspected. Our intention in this book is to help readers reach the initial level of diagnosis.

Once you have confirmed the problem, if you are not familiar with it, some background will be required. By supplying information about the economic importance, life cycle and control of each disease, pest or disorder, we hope that an appreciation can be achieved. The selected references provided can act as a basis for further research, especially if there is little access to scientific literature databases. For some diseases and pests, scientific knowledge is published continuously, and it is impossible to include the most up-to-date references. For other problems, especially disorders, there has been little study or published work and, as a result, some of the references may be old.

This book is intended as a practical guide and tool. We expect and hope that it will be carried around and referred to in the field, as well as in the laboratory, on an everyday basis. We hope that it will prove a valuable asset to all who use it.
