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.
Diversity and Evolution of Land Plants provides a fresh and long overdue treatment of plant anatomy and morphology for the biology undergraduate of today. Setting aside the traditional plod through the plant taxa, the author adopts a problem-based functional approach, exploring plant diversity as a series of different solutions to the design problems facing plant life on land.
"This Directory is a facsimile reprint of the original Eva Crane classic that was published in 1984. From the thousands of plant species on which they had collected data, Eva Crane and her team selected 467 which could be justifiably described as the 'important world honey sources' of the book's title. For each plant species, data is provided on its economic and other uses, how much nectar / pollen and/or honeydew it provides, honey flow data (if any exist), and concerning the honey's chemical and physical properties."--Page 4 of cover.
This professional horticulture reference, which has been in print continuously since 1932, is fully revised and updated in this new edition. Based on real-life experiences from industry professionals including growers and equipment and greenhouse manufacturers, the presented information covers all aspects of greenhouse equipment -- the structures themselves, benches, irrigation, curtains, environmental controls, machination, and the greenhouse as a retail facility. The most recent developments in greenhouse evolution are discussed, as are the varieties of available greenhouse structures, from free-standing and gutter-connected greenhouses to shade houses and open-roof greenhouses. Information on the business side of managing a greenhouse is provided, including how to market products and how to operate a retail store from a greenhouse.
