Pests and Diseases of Potatoes A Colour Handbook
Platt Bud, "Pests and Diseases of Potatoes: A Colour Handbook"
2006 | pages: 177 | ISBN: 1840760214 | PDF | 13,5 mb


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 Handbookis 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 descrip-tion is an essential next step on the road to correct iden-tification. In this book, each disease, pest or disorder has a detailed description of the symptoms and, where relevant, the vectors that transmit the disease.
