It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

"Botanically speaking, tomato is a fruit. But by common understanding it is often considered a vegetable as well. Regardless of which term you use, tomato is the most "Googled" fruit and one of the most commonly grown. Unfortunately, tomato plants are also a common target for many diseases and pests, affecting production for anyone growing the crop, including commercial producers trying to maximize yield and the small scale gardener who wants flawless and flavorful garden fresh tomatoes for salads, cooking, and canning. Enter Compendium of Tomato Diseases and Pests, Second Edition. The nearly 250 images and associated information in this highly useful and significantly upgraded book allows anyone-from the gardener to professional-to identify, understand, diagnose, and treat more than 60 diseases of tomato occurring throughout the world. This impressive new handbook, written by expert plant pathologists working with this crop, includes nearly 20 new diseases and disorders, including those caused by fungi and oomycetes, bacteria, phytoplasmas, viruses and viroids."--Publisher's description.

"This all-new disease and insect compendium for sunflower crops will serve as a vital field guide at universities, extension offices, diagnostic labs, farms, and even homes where sunflowers are grown. It includes nearly 300 images and research-based management recommendations, allowing users to scout, identify, and manage a range of plant diseases and insect pests of sunflowers whether they're grown for food or décor!"--

Disease resistance is one of the major factors that can be improved to sustain yield potential in cultivated crops. This book looks at disease resistance in wheat, concentrating on all the economically important diseases - their economic impact and geographical spread, breeding for resistance, pathogen variability, resistance mechanisms and recent advances made on resistance genes. Newer strategies for identifying resistance genes and identify resistance mechanisms are discussed, including cloning, gene transfer and the use of genetically modified plants. It is suitable for researchers and stu.
