Podblight op the Lima Bean Caused by Diaporthb phaseolorum 
Plate 42. Diaporthe phaseolorum: A.—A leaflet of Phaseolus lunatus L., show¬ 
ing a number of ragged holes of various sizes caused by the Lima bean 
podblight fungus. B.—A green Lima bean pod photographed 10 days after 
inoculation with the ascospore strain. C. —A pod showing the characteristic 
manner in which the fungus rapidly overruns it soon after it is killed, 
pycnidia/orming indiscriminately over the entire surface. 504 
Plate 43. Diaporthe phaseolorum: A.—A vertical section through a pycnidium 
from the leaf. B.—A vertical section through a pycnidium from a pod 
showing the beak and the thickened dark wall surrounding it. C.—A 
vertical section through the epidermis and underlying host of a portion of a 
diseased pod showing the connection and chambering of the pycnidia. 
D.— A somewhat diagrammatic drawing of a portion of the surface of a Lima 
bean pod, showing the distribution of the perithecia, the shape of the beaks, 
’and their projection from the surface. E.—A surface view of a portion of 
a bean pod showing arrangement of the pycnidia and fusion of the beaks. 
F.—A vertical section through a perithecium from a pod. 504

Bacterial-Blight or Barley 
Plate B. i.—H ealthy barley leaf for comparison. 2.—Early stage of bac¬ 
terial-blight showing a translucent, water-soaked stripe along the midrib, 
yellowing toward the apex. 3.—More advanced stage of bacterial-blight 
of barley where numerous local invasions have developed. 4.—Barley 
seedling showing abundant infection spots on the lower leaf from atomizer 
inoculation with strain isolated from old infected seed. 5.—Barley seed¬ 
ling similarly infected with strain isolated from blighting leaf. 644
