"Tomato yellows" is merely a new name for that old plague of the West which has been more or less generally known as western yellow tomato blight. Plant pathologists of the Idaho (1904) and the Washington (1922 and 1924) State Agricultural Experiment Stations, where this disease has been studied for a greater number of years than at any other institution, have used the name "yellows" in their annual reports. The writer now recommends that this name be used in the future generally and exclusively in preference to and in place of any other synonyms, such as western blight, yellow blight, summer blight, or simply blight. There are several reasons, both scientific and practical, for adopting this name.
