ISSN 0097-1372


In the summer of 1922 a series of experiments was carried on at the Scotts Bluff Experiment Substation for the purpose of finding, if possible, a formula for preparing an inexpensive and efficient poisoned bait for grasshoppers that could be recommended to the farmers of the North Platte valley, and also of learning more concerning the relative values of certain attractants and poisons commonly used in such baits, as well as the best time to scatter them to obtain the most satisfactory results. While the results were fairly conclusive from a qualitative standpoint, the time was not available in the summer of 1922 to secure data that would enable the recommendation of a formula giving definite quantities of the ingredients. The experiments were continued, therefore, during the summer of 1923, to secure these lacking data, and the present bulletin is a report giving the final conclusions reached from the experiments of both 1922 and 1923.
