Lincoln they were more plentiful and spores continued to issue 
from some of them for nearly three weeks in large numbers, and 
in greatly reduced numbers for several days longer. The spray 
schedules were so arranged that plats could be sprayed at inter- 
vals of about 10 days during the heavy dissemination of spores. 
The severe injury due to Bordeaux russeting, together with the 
fact that Bordeaux proved more efficient than lime sulphur, led to 
an interchange of Bordeaux and lime sulphur applications in some 
of the schedules in order to ascertain if it were not possible to con- 
trol blotch with a minimum amount of injury.
