Excerpt from Plant Pathological Investigation in the United StatesAs the research on diseases of forage cr0ps increased in Scope, this was recognized in 1928 by a change in name to the Division of Forage Cr0ps and Diseases.The Division now employs nine plant pathologists for full time work on forage cr0ps dis eases. In addition, cooperative agreements are in existence with three State experiment stations, under which the Division pays a portion of the salary of a plant pathologist working on forage diseases while the State pays the remainder of the salary. In still other States, pathologists are under appointment in the Division as collaborators without pay and direct the work of a graduate student employed by the Division on a part-time basis for work on a Speci fic forage disease problem. This increase in the number of plant pathologists working on forage cr0ps diseases during the past twenty-four years is indicative of the increased import ance legumes and grasses have assumed in American agriculture during that period.While the early work on forage diseases in the Bureau centered largely around the diseases of cowpea alfalfa, and clover, the importance of diseases in the culture of winter legumes was recognized later and work was started on the diseases of winter pea, vetch, and lupine The greatly increased use of grasses, which resulted from the agricultural adjustment and soil conservation programs, emphasized the need for more knowledge of the diseases of hay and pasture grasses. Still more recently, the rapid increase in soybean acreage during the period of World War II, when soybean imports from the Orient were cut off, resulted in an increase in the prevalence of diseases on this crop and led to the initiation of a broad program of research on soybean diseases.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
