Certain tomato varieties are known to be resistant to curly top,3 formerly known as western yellow blight. Curly top is transmitted, in the United States, to beets, tomatoes, and a great variety of other host plants by the leafhopper Euttetix tenellus (Baker). As the absence of disease in some previous trials of resistance in tomato varieties was believed to be due to a lack of infective leafhoppers, viruliferous leafhoppers were confined on the plants in some of the experiments reported in this paper. However, trials under natural infestation were thought to be still necessary to test the value of natural resistance as a practical means of control. Accordingly, it was decided to make use of both natural and artificial infestation. An account of trials with natural infestation during three years, 1922-1925, has previously appeared in this journal.(5)
