Oreg. The Detection and Identification of Plant Pathogens 



Associated vd.th Forage Legiime Seed , (l) Detect, identify, 

 and learn pathogenicity of organisms associated with forage 

 legume seed. (2) Develop methods for detection of plant 

 pathogens associated with forage legume seed applicable to 

 improved seed testing procedures. 



Bot., PI. Path., Farm Crops 178 (^-35) 



Oreg. Forage Legume Diseases , (l) Survey diseases of Oregon 

 forage legumes and learn their distribution and severity in 

 terms of economic loss. (2) Study the etiology of the major 

 diseases of forage legumes. (3) Develop or adapt practical 

 methods for controlling diseases of forage legumes. (A-) 

 Identify aind clarify taxonomy of pathogenic fungi associated 

 with forage legumes. 

 Bot., PI. Path. 335 



S. Dak. Investigations and Control of Alfa,lfa and Other Forage 

 Legume Diseases . To (l) identify and assess prevalence and 

 economic importance of various diseases of alfalfa and other 

 forage legumes; (2) study biology of pathogens causing diseases 

 with a view to understanding prevalence, survival, and control 

 in the field, and manipulations for extensive plant inocula- 

 tions in greenhouse; (3) discover cultural and other practices 

 to reduce destructiveness of diseases in the field; (4) evaluate 

 disease resistant qualities of various clones and strains of 

 alfalfa and other forage legumes currently developed or 

 studied; and (5) study nature of disease resistance in certain 

 alfalfa clones to some of the pathogens. 

 PI. Path. 230 



Tex. Evaluation and Improvement of Legumes . To (l) collect 



native and introduced legumes and learn their adaptation to 

 the various climatic and soil conditions of the state; (2) 

 select plants or strains possessing combinations of desired 

 characteristics such as forage and seed yield, forage quality, 

 palatability, stand longevity, resistance to diseases, insects 

 and drouth, ability to grow successfully with other species, 

 winter hardiness, seasonal growth, and vigor of recovery after 

 defoliation; (3) study response of legumes to different 

 fertility levels; (4) combine by breeding methods into a 

 single plant or strain as many superior traits as possible; 

 (5) study factors that may aid in increasing seed production; 

 and (6) conduct extensive strain tests with improved material 

 and increase foundation seed in accordance with objective No. 2.
