This book was released on 2017-11-12 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Bacteriosis (Blight) Of the English Walnut in California and Its Control The present paper is concerned primarily with results obtained in spray ing experiments for the control of bacteriosis (blight)3 of the English walnut that have been conducted on a large scale at widely separated points in California since 1927. Walnut bacteriosis is not a new disease. In relation to the history of walnut culture in California it may be considered rather an old one. Be tween the time when bacteriosis was first observed over forty years ago and the present, much important information about it has been obtained and published. For the sake of clarity, however, as well as to make the control data presented herein easier reading for the grower for whom this paper was written or for the plant pathologist who may never have made a study of the disease, a digest of the known basic facts concerning it has been prepared.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Melaxuma of the Walnut, "Juglans Regia" A Preliminary Report It is the purpose of this bulletin to report the results of an investiga tion begun in June, 1913, relating to the cause and control of a comparatively new disease of English walnut trees in California. This disease, known as Melaxuma, which occurs in the form of black cankers in the crotches and limbs, and occasionally in the form of a sudden wilting and dying of the branches, has been noticed by walnut growers in Santa Barbara County for a number of years (at least since but has only attracted serious attention during the past two or three years. Because of the oozing of dark watery material to the surface of affected areas, this disease is often confused, under the name of black sap, with sunburn, frost injury, injuries to the bark in cultivation, injury from the decay of wood at places where limbs have been cut off, and other troubles in which a black sap may ooze out during the active growing period of the tree. It should not be taken for granted, therefore, that because a black ooze is seen on the trunk or larger limbs of a walnut tree that Melaxuma is necessarily present.

Book excerpt: Excerpt from California Walnuts, Almonds, and Chestnuts; Their Composition and Draft Upon the Soil, And, the Bleaching of Nuts by Dipping The chief ingredient of the walnut and almond kernel is the fat (oil), of which in the walnut there is about and in the almond nearly for both the European and the California-grown nuts; this is nearly equal to the Oil content of the olive On the other hand, the fat (oil) of the chestnut kernel is but a small fraction of the meat, viz., from about in the European to about in the Pennsylvania chestnut. The next largest constituent of the almond and walnut kernel is the protein, or esh-forming ingredients - in the almond, upward of to and in the ordinary walnut, about in the chestnut there is only about or about one half that of the other nuts. About three fourths of the chestnut kernel is made up of starch, sugar, dextrin, etc. - nitrogen-free extract ingredients, which, like the fat, furnish fuel to the body, though less economically. Of the stone fruits the prune and apricot, like the chestnut, are largely made up of carbohydrates (sugar, etc.) and contain considerably less protein than the chestnut kernel, and from three to six times less of that ingredient than the almond or walnut kernel. The above figures are interesting among themselves, and become of more value when considering the food values of these nuts. All authorities agree upon the fact that nuts are a highly concentrated form of food; caution should, therefore, be followed in their use. Walnuts and almonds possess a higher nutritive value than even the grains; and, as compared with fruits, they rank high in food value, being the true seed only and not made up of eshy coverings, as the apple, pear, etc.; they, therefore, have less water and a higher nutritive value generally, weight for weight.

Available in PDF, EPUB and Kindle. Book excerpt: Bruce E. Tabashnik and Richard T. Roush Pesticide resistance is an increasingly urgent worldwide problem. Resistance to one or more pesticides has been documented in more than 440 species of insects and mites. Resistance in vectors of human dise8se, particularly malaria-transmit ting mosquitoes, is a serious threat to public health in many nations. Agricultural productivity is jeopardized because of widespread resistance in crop and livestock pests. Serious resistance problems are also evident in pests of the urban environ ment, most notably cockroaches. Better understanding of pesticide resistance is needed to devise techniques for managing resistance (Le. , slowing, preventing, or reversing development of resistance in pests and promoting it in beneficial natural enemies). At the same time, resistance is a dramatic example of evolution. Knowledge of resistance can thus provide fundamental insights into evolution, genetics, physiology, and ecology. Resistance management can help to reduce the harmful effects of pesticides by decreasing rates of pesticide use and prolonging the efficacy of environmentally safe pesticides. In response to resistance problems, the concentration or frequency of pesticide applications is often increased. Effective resistance management would reduce this type of increased pesticide use. Improved monitoring of resis tance would also decrease the number of ineffective pesticide applications that are made when a resistance problem exists but has not been diagnosed. Resistance often leads to replacement of one pesticide with another that is more expensive and less compatible with alternative controls.
