Book excerpt: Excerpt from Report of the Plant Pathologist to July 1, 1906 In the spring of 1904 pear blight appeared very extensively in the Sacramento Valley. Much alarm was felt by the growers, knowing the history and result of the disease in the San Joaquin, and the Experiment Station, the various County Boards, the State Com mission of Horticulture, and the U. S. Department of Agricul ture were called upon for advice and relief. This Division being new at the time, consisting of the writer alone, nothing could be done dur ing the summer of 1904 except to determine the extent of the outbreak by much traveling about through the whole northern region, and to assist the growers as much as possible by advice as to the nature of the disease and the best known treatment, and by inspecting their orchards. The blight developed extensively that summer and invaded most of the important pear districtsfi In March, 1905, appropriations of the Legis lature of that session made available to the Station about for the investigation of pear blight during the succeeding two years. Meantime, Professor M. B. Waite, the leading authority on pear blight, had been sent to California by the U. S. Department of Agri culture, to lend all possible assistance to the growers. Considerable activity was also being displayed by the State and various County Boards of Horticulture in a desire to do what was possible toward suppressing this disease.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pear Growing in California Seeds of commercial pears were planted in the early days of mining in the Sierra foothills of the Sacramento and San Joaquin valleys, and a few oriental pears were set out by the Chinese immigrants. Later, graft ing wood and grafted trees of many varieties, brought from the missions, from eastern states, and even from Europe, were grown to supply fruit to miners and other new settlers. With the discovery of gold, certain enterprising young men who had come in search of the precious ore found that more money could be made by supplying fruit for the satisfaction of the prodigal miners, than by panning gold; and pear growing gained impetus. According to Wickson, the Bartlett was brought around the Horn in 1850 and planted in the Napa Valley. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book How to Control the Pear Thrips Classic Reprint written by S. W. Foster and published by . This book was released on 2015-08-05 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from How to Control the Pear Thrips By the time the fruit buds have swollen sufficiently to separate the bud scales slightly at the tip the adults force their way within, feeding upon the tenderest portions inside the buds. When the thrips are present in sufficient numbers the buds are completely destroyed and the trees fail entirely to bloom. Eggs. - As soon as the first leaf surfaces or fruit stems are exposed egg laying usually begins, depending somewhat on the variety of fruit attacked. The first eggs are deposited the last days of February and oviposition continues till near the middle of April, being at its maximum, however, from the 10th of March to the 1st of April. Most of the eggs (fig. 3) are deposited just under the epidermis in the fruit stems, young fruit, and leaf stems. The eggs require from five to seventeen days to hatch, the average time being about eight days. Larvae. - By the time the trees are breaking into full bloom the adults have done most of the damage caused by their feeding, and oviposition is at its height. Many of the earlier appearing adults are dying off and larvae (fig. 4) are beginning to appear in numbers. The very first larvae can usually be found about March 20, and are in maximum numbers on the trees, feeding on the small fruit and young foliage, from the first to middle of April. Reaching their full development, the larvae drop from the trees, of their accord or with falling calyces, or are blown by wind or knocked off by rain.
