Va. Diseases of Pasture and Forage Crops , To (l) determine 



strain of stem nematode of alfalfa present in Virginia and 

 to develop a rotational sequence effective in controlling 

 the disease, (2) determine by survey extent of stem 

 nematode infestation in the state, (3) learn effect of other 

 plant parasitic nematodes upon the several forage legumes 

 and grasses, (i+) study leaf pathogens of orchard grass 

 (Puccinia graminis and Scolecotrichum graminis ) as to their 

 pathogenic variability, influence of environmental factors 

 upon their development and greenhouse inoculation techniques 

 for evaluating resistant clones, (5) to learn disease 

 incidence of the uniform red clover nursery supplied by 

 Division of Forage Crops and Diseases of USDA, (6) assist 

 plant breeders in evaluating lines of birdsfoot trefoil 

 bromegrass, alfalfa, and orchard grass for disease 

 resistance from field observations.
