Rust caused by Gymnosporangium juniperi-virginianae was rather severe, 
according to Pipal, in the southeastern part of the state. The abundance 
of the red cedar in southern Indiana is of course very conducive to rust 
epidemics. 
Oskamp reports that blister canker due to Nummularia discreta is in- 
creasing in importance in Indiana and further reports its extreme severity 
on the Ben Davis variety near Greencastle. It is also reporied to be present 
on that variety in an orchard near Peru. 
According to the observations of Oskamp and Pipal, bitter rot caused 
by Glomerella cingulata was not as destructive as usual this year. Bitter 
rot occurs mainly in southern Indiana. 
A serious root trouble occurs to a considerable extent in central and 
southern Indiana, especially on the Grimes variety. This root rot usually 
results in the death of the affected trees and cases are on record where 
whole orchards haye been destroyed in the southern part of the state. 
Whether or not this is the Xylaria root rot has not been ascertained. 
Frost injury to apple blossoms was of course severe in certain sections of 
the state and caused a marked reduction in yield. A very bad case of this 
was noted in a large orchard near Goshen where absolutely all of the blos- 
som clusters were killed. A peculiar crinkling of apple leaves due to the 
death of the lower epidermis was very widely noted during June and was 
attributed to freezing injury. There was a marked prevalence of frost 
marking of the fruit in the central and southern parts of the state in all 
stages from narrow frost bands and blossom-end russet to russeting of the 
entire surface of the fruit, and even malformation of the fruit. So prevalent 
was this type of injury that it assumed considerable significance as a blem- 
ish in the prize exhibits in the shows. 
The lace-like russeting of the fruit resulting from Bordeaux injury and 
arsenical burning of the foliage was found in sprayed orchards. 
ASPARAGUS. 
Rust caused by Puccinia asparagi was not found in the Indianapolis 
market gardens but was noted at Lafayette. 
ASTER. 
Fusarium wilt was severe locally. 
3ARLEY. 
Thirty-six barley fields in 15 counties were examined in the federal cereal 
disease survey. Ergot caused by Claviceps purpurea was found in two fields. 
Spot blotch caused by Helminthosporium sativum was reported from eight 
fields, net blotch caused by Helminthosporium teres from 11 fields, and 
stripe caused by Helminthosporium gramineum from two fields. Spot blotch 
is the most serious of these diseases in Indiana and was very abundant 
in the eight fields above noted, all of which were in Madison, Delaware and 
Noble counties. Scab caused by Gibberella saubinetii was found in 19 or
