W. Va. Diseases of Forage Grasses . Ho determine (l) what 



reduction in yield may be caused by the common diseases of 

 major forage crop grasses cultivated in West Virginia, 

 principally, timothy, orchard grass, blue grass, red top, 

 brome grass, and tall fescue; (2) host, range and pathogenic 

 capabilities of various diseases of forage grasses; and 

 (3) vjhether the amount of loss caused by individual diseases 

 can be reduced by the use of disease resistant selections by 

 alteration of culture and management prgictices, or by other 

 means*

Wash. 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. 

 PI. Path. 864 



Wash. Virus Diseases of the Cereals and Grasses . Learn virus 



diseases of oereals 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.

Wash • The Influence of Specific Organic Compounds in the Soil 



Solution (other than Antibiotics) on the Development of the 

 Root and Crown Rots of Cereals and Grasses . Learn influence of 

 specific organic compounds on development of root and crown 

 rots of cereals and grasses (if they increase or decrease 

 disease level) and if they influence formation of resting 

 spores or other structures of survival formed by pathogens 

 within diseased root and crown tissues.
