Cereal Rusts Of The United States PDF Download

Excerpt from Cereal Rusts of the United States: A Physiological Investigation Sir: I have the honor to transmit herewith a report on the cereal rusts of the United States, prepared by Mr. Mark Alfred Carleton, of this Division. Mr. Carleton has been engaged in an investigation of the diseases of cereals for several years and this report contains, in part, the results of the work. The several species of rusts affecting cereals in the United States are fully described, and the distribution of these rusts is given, together with a detailed statement of the results of extensive observations and experiments to determine the rust resistance of numerous varieties of wheat and oats. The life history of the rusts themselves has been very fully studied and the facts obtained from this work throw important light on problems connected with the breeding of rust-resistant varieties. In view of the wide distribution and the destructiveness of the rusts and the value of the results obtained, I respectfully recommend that the report be published as Bulletin No. 16 of this Division.
