Download or read book Residue Reviews R ckstandsberichte written by Francis A. Gunther and published by Springer. This book was released on 1971-04-06 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.

Book excerpt: Developed especially for use by backyard orchardists, rare fruit growers, and small-scale growers, The Home Orchard offers a comprehensive look at standard growing methods, as well as some innovative practices that enthusiasts have developed in recent years, some of which are uniquely suited to the small-scale grower. You will learn how trees grow, which species grow best in the different regions and soils, varieties from which to select, preparing the soil, planting, watering and fertilizing, pruning and grafting, thinning the fruit, diagnosing problems, controlling pests, and harvesting. You'll also find special attention given to organic and non-toxic pest management and fertilization methods. Key pests and diseases are identified and natural control methods are emphasized. Irrigation methods for the backyard grower are discussed and the difficult task of how often and how much water to apply is simplified. The focus is on giving the trees enough water but doing so in an efficient, water-saving manner. Included are hundreds of photographs and diagrams that clearly show how to produce the best crops. Photos of several practices, such as key budding and grafting methods, are depicted in step-by-step photos. No other publication provides this breadth and depth of coverage --

Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
