Epidemiology of Leaf Spots and Other Foliage Disease of 

 Crop Plants. — II. Corn and Small Grain Diseases . To determine 

 number, prevalence, and distribution of physiologic races of 

 important pathogens that cause foliage diseases of corn and 

 small grains and also the relative importance of such diseases 

 in breeding disease-resistant varieties. 



PI. Path., Bot. FH -2219-2 



Diseases of Small Grains t Virus Diseases of Oats and Other 

 Cereals. Identify and differentiate the kinds and strains of 

 viruses attacking oats, study their importance, aid in develop- 

 ment of improved techniques for these studies. 



PI. Path. 132-8, Coop. ARS 



Root Diseases of Small Cereals, and the Nematode Relation- 

 ship . To (l) continue basic investigations of root disease- 

 inciting organisms, as to occurrence, relative importance, 

 pathogenicity, taxonomy, and influence of environmental factors; 

 (2) seek control of certain cereal root diseases by means of 

 breeding, cropping practices, and fungicides; and (3) study 

 root disease-nematode relationship in cereals.

Diseases of Barley. Oats, and Wheat and Breeding of 

 Disease-jlesistant Varieties . To (l) develop varieties of 

 barley, oats, and >iheat resistant to rusts, smuts, powdery 

 mildew, and other damaging diseases; (2) culture organisms 

 causing the diseases, and learn effects of environment on 

 them; (3) study histologically and physiologically the 

 processes of diseases caused by these organisms; (4) study 

 genetics of causal organisms and related cytological phenomena} 

 (5) develop methods of control of small grain diseases and 

 promote use of known methods; and (6) study inheritance of 

 resistance to small grain diseases.

Investigations on Root Rots and Foot Rots of Cereals and 

 Grasses in Eastern Washington . To (l) learn distribution, 

 prevalence and economic importance of root and foot rots of 

 cereals and grasses in Eastern Washington; (2) learn cause(s) 

 of these diseases; and (3) develop control measures.

Virus Diseases of the Cereals and Grasses . Learn virus 

 diseases of cereals and grasses in state, their distribution, 

 prevalence and severity, cereals affected, forage and weed 

 grasses harboring them, and pertinent factors in spread of 

 disease. Develop resistant varieties or other control.
