Bulletin No. 370 - The Superb Plant Bug, Adelphocoris Superbus (Uhler): Its Life History And Its Relation To Seed Development In Alfalfa, Charles J. Sorenson, Lowell Cutler
UAES Bulletins
Infestations of the superb plant bug, Adelphocoris superbus (Uhler), in Utah alfalfa fields first came to the attention of entomologists of the Utah Agricultural Experiment Station during their investigations of the seed chalcid and lygus bug problems of alfalfa seed production in the Uinta Basin from 1926 to 1934. Because of its occurrence in considerable numbers, particularly in first crop alfalfa fields with thin stands, the superb plant bug was suspected of interfering with seed development. Consequently an investigation of the activities of this insect was begun in the summer of 1932 and continued through that of 1933.

Stem Blight Of Alfalfa In Utah: A Complex Of Two Distinct Diseases, William E. Rader
Stem Blight Of Alfalfa In Utah: A Complex Of Two Distinct Diseases, William E. Rader
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In 1908, Sackett described for the first time what appeared to be a new bacterial disease of alfalfa in Colorado. To this particular disease he applied the name “stem blight" and attributed the cause to a bacterium, Pseudomonas medicaginis n. sp. For some two decades or more Sackett's work on this disease was accepted. During this time stem blight, which was first thought to be indigenous to the western United State, was reported from nine states east of the Rocky Mountains. In 1933, Johnson and Valleau described a disease of alfalfa, characterized by stem lesions very similar in appearance to …
Bulletin No. 180 - The Irrigation Of Alfalfa, F. S. Harris, D. W. Pittman
Bulletin No. 180 - The Irrigation Of Alfalfa, F. S. Harris, D. W. Pittman
UAES Bulletins
In the United States alfalfa-growing has gone hand in hand with the development of irrigation. Alfalfa did not become an important crop in the country until after irrigation began to be practised in the West. Very soon after the pioneers reached Utah, alfalfa was brought to the state where it found conditions well suited to its growth. Wherever settlement extended alfalfa was raised as one of the most important crops, and finally from the West it has spread eastward into the humid parts of the country.
Bulletin No. 171 - Alfalfa Seed Growing And The Weather: With Particular Reference To Conditions In Utah, J. Cecil Alter
Bulletin No. 171 - Alfalfa Seed Growing And The Weather: With Particular Reference To Conditions In Utah, J. Cecil Alter
UAES Bulletins
The demand for alfalfa seed has far outrun domestic production. Since the labor and expense of producing the crop are light, and the profits attractive in favorable years, a desire is manifest wherever alfalfa is grown, to save a crop for seed whenever the meteorological elements favor its setting and maturing. Climate is generally acknowledged to be the limiting factor in alfalfa seed production, and the current weather the major factor affecting the yearly yields.
Circular No. 10 - The Control Of The Alfalfa Weevil, E. G. Titus
Circular No. 10 - The Control Of The Alfalfa Weevil, E. G. Titus
UAES Circulars
During the work with the alfalfa \weevil throughout several very different seasons and in different regions, of the State, a number of methods of control have been developed that bid fair to be of service in combating this insect. The prospect for the alfalfa grower in the infested area looks more hopeful each year. It is the purpose of this circular to give a brief account of the alfalfa weevil, its present distribution, and the principal methods that appear to be of value in its control.
